Slicing benefits

  • Increase in tire mileage by 20-30% of the mileage of a new tire. This is because on a long distance truck, the wear rate of a new tire is twice that of the one that reaches the wear indicator. The wear rate decreases with the wear itself. That is why the deepening of the tread of a worn tire by only 3-4 mm can significantly increase mileage.
  • Reduced fuel consumption. If we compare a new tire with a tire that has reached the groove indicators (2–3 mm residual depth), then a more worn tire shows less deformation of the tread rubber, heats up less and, as a result, has less rolling resistance, and thus consumes less fuel. On a straight road, the rolling resistance of a new tire can be taken as 100%, then for a tire that has reached the wear indicator, it will be only 75%. Between these extremes, the rolling resistance is proportional to the residual tread depth (tread wear). A chopped tire operates with the lowest rolling resistance and, as a result, the lowest fuel consumption throughout its life.
  • Improving the traction and grip properties of the vehicle. Cutting restores edge sharpness and tread depth to 6–8 mm, which allows the car to move more confidently and safer on wet or slippery roads.
  • Re-repairing a chopped tire. After the cut tire is worn out, you can restore the tread by welding and repeat the cutting procedure, thereby once again postponing the purchase of new rubber.

Tread cutting. new life of old rubber

How to potentially increase tire mileage, reduce fuel consumption, and thereby reduce financial costs are issues of constant concern to motorists and tire manufacturers. These issues are especially relevant in the case of truck tires. When developing new models, engineers of different tire companies increasingly include the possibility of cutting a tire tread. Cutting the tread is one of the surest ways to extend tire life and save money. We have already written about cutting on the pages of our magazine and once again we want to remind you of the basic rules and stages of this process.

Tread groove basics

The essence of the cutting operation is to remove part of the existing rubber layer, that is, deepening the channels and grooves of the tread.

To do this, already at the design stage, tire manufacturers put a rubber layer in the tread structure (highlighted in blue in Fig. 1), intended for subsequent high-quality cutting without reducing the strength properties of the tire and its integrity.

Both new and retreaded truck tires can be cut. The main thing is that on the sidewall there is a corresponding marking “U” or “Regroovable”, informing that cutting of this tire is allowed. Often, “craftsmen” cut tires that are not at all intended for this procedure. You should not go on risky experiments, subjecting ordinary tires to cutting. On the road, the consequences of such experiments can be unpredictable and dangerous.

The slicing process is quite simple. To begin with, the tire is dismantled from the disk, checked for damage to the tread, sidewalls and sides. Next, remove all unnecessary objects (stones, carnations, etc.) that could have gotten into the grooves of the tread. If necessary, the tire is repaired.

protector, tire

The cutting parameters must be determined individually for each type of tread and size. In the catalogs of truck tires of almost any tire manufacturer, for each model that can be cut, a cutting map is provided (see examples in Fig. 2). It indicates the depth and width at which it is permissible to cut. Experts recommend that the residual tread depth of the tire before cutting is at least 3mm.

It is very important to choose the right blade depth for slicing. Tread depth measurements before cutting should be taken around the tire circumference at several points in order to determine the actual minimum tread depth. And then set the tool cutter to a depth equal to the sum of the minimum residual tread depth and the maximum cutting depth recommended by the manufacturer’s catalog for this tire.

Many tires have built-in tread depth indicators (see Fig. 1) that not only indicate when it’s time to groove, but also allow you to determine the correct cutting depth.

Particular attention should be paid to a tire with traces of uneven tread wear.

If the tire is unevenly worn, you can only cut the worn section if the groove marks are still visible. Ensure that the residual rubber thickness between the deepest cutting point and the steel jacket is at least 2-3 mm.

After finishing the cutting process, make sure that the tire is not damaged and that the straps of the belt are not exposed.

Slicing equipment

The modern market offers a fairly wide range of tread cutting machines powered by a network: from cheaper Chinese (about UAH 2,500) to expensive European and American (on average, from UAH 4,000 and above).

Each such apparatus is supplied with a set of knives of different lengths, which, depending on the shape and width of the blade, are designated by numbers from 1 to 6 and are divided in shape into rounded and trapezoidal.

What the law says

Most European countries are very loyal to slicing. Even in Germany, which is famous for its restrictions, it is forbidden to put chopped tires only on the front axle of buses. Freight and bus carriers operating in European countries need to know the national regulations of each country on the itinerary regarding the use of chopped tires in order to avoid claims from the local traffic police. For example, for the European Union countries, you can use the ETRTO (European Tire and Rim Technical Organization) directory, which contains some national regulations restricting the use of tires, as well as links to regulatory documents.

In the table, we summarize the legal requirements for tire cutting in different European countries.

I would like to say that tread cutting is a painstaking process that requires special skills, which should be entrusted only to a good specialist who knows the technology of its implementation in accordance with the recommendations of the manufacturers.

DIY car tire tread cutting

Quite often it happens that even a fairly frayed and bald rubber can serve as faith and truth for a period of time. It’s worth noting that grooving your tires is the only way to slightly extend the life of your already worn rubber. It is imperative to follow certain rules and features in order to perform this procedure as correctly and reliably as possible.

How to cut tires with your own hands

If used correctly, a truck tire can last for at least a couple of years. You need to understand that cutting should be done only if the depth is already less than 1.6 millimeters. The slicing process is simple enough.

Before performing this procedure, you need to select the required depth. The work should be done by the regruver. The cutting is carried out exclusively on the old tracks, there is no need to invent something new. Also, the tread depth must comply with the regulations.

Advantages and disadvantages of the procedure

There are certain pros and cons of using this procedure, which you should definitely pay attention to.

Among the main poles are the following.

  • A significant increase in service life. In some cases, due to the incorrect execution of the procedure, certain problems may arise. For this reason, you must strictly follow the rules that will be presented below.
  • Significant reduction in fuel consumption. With a good tire, it is possible to save up to a quarter of the fuel used, which is certainly very important. The tread depth and width must be selected individually.
  • There is, in fact, only one minus. This is a rather dangerous movement in such a car. Wheels with a road surface must be made especially well. This is especially true for trucks.

How to determine if tires can be chopped

Slicing solid tires is only possible if specified by the manufacturer. Among other things, you can use this service in Russia only in specialized companies. Although some non-professional companies are also willing to offer you this service, the quality may not please you.

It is imperative to know that the standard tire pressure is 22.5 radius and 8 atmospheres. If there is even a slight deviation in depth, there is a high probability that the tires will last you significantly less. If everything matches the specified parameters, then this procedure can be performed without any problems.

Slicing technology

Truck cutting should be done on tires without significant abrasion of the rubber. A high-quality result is possible if the correct design specifics are used. A gap of a few millimeters is required, which can allow the tread to deepen without too much trouble.

The tread is cut not only on new tires, but also on used ones.

Which tires should be cut

This procedure is performed primarily on trucks. Cutting of all-metal tires is made, made with an additional layer of rubber and a specialized reinforced frame. On a passenger car, this procedure will not work for the reason that an additional layer on the rubber simply does not exist.

It is possible to perform the cutting procedure if the tire has a special regroovable marking. It is worth operating the tread on trucks until the moment when you can change old tires for new ones.

The main purpose of the tire tread

The primary role of tire treading is to maximize the performance of the tires themselves. There are circumstances when buying new tires is not possible. However, there is a way out of this situation, and it is quite simple and not too expensive. Basically, the groove on the tread is nothing more than a special pattern that significantly improves traction. Among other things, you need to understand that protectors are cut in specialized companies, however, you can perform this procedure, including at home.

Correctly grooved tires will significantly improve traction, even on difficult terrain. It should be understood that this procedure is only possible in certain situations. If your rubber is too worn out, then such a procedure will help you for a short period of time.

Tire cutting technology

Cutting the tread of truck tires is an increase in the deepening of the grooves and channels of the tread due to the removal of a small layer of rubber without reducing its basic properties. The result is achieved due to the specifics of tire design. at the development stage, a “gap” of several millimeters is provided, which allows you to deepen the tread without losing the strength and integrity of the coating.

In principle, not only new tires, but also remanufactured tires can be cut, the main requirement is a special marking that allows such manipulations. If your tire has a “U” badge or “Regroovable” inscription, then you can safely contact the service station for a similar service. It is not worth experimenting. cutting rubber on a truck is a responsible task and making indentations on your own, without experience and skills, is not only unreasonable, but also unsafe. An improperly processed tire can lead to irreparable consequences at any time.!

Cutting the tread of truck tires.

The most commonly cut tires are R22.5, although there are also smaller tires for which the manufacturer provides for the tread deepening. If you are in doubt whether it is possible to cut your tires, call us and the master carver will advise you absolutely free of charge. Please note that ONLY CARGO tires are to be cut. The manufacturer of such tires provides for this procedure, applies additional layers of rubber and reinforces the tire carcass. We are writing about this here because the service of cutting passenger tires has become popular in Russia, and many services do not hesitate to do this. Also, almost all salons and outbids of used cars cut passenger tires in order to give a cheap gloss to the car being sold. Never do this. it is life threatening. The passenger car tire manufacturer does not provide for this procedure. Such a tire can burst on any bump or stone. Especially at high speed. In addition, pre-cut passenger tires are not subject to balancing. Do not save on your safety, if your passenger tire is worn out. buy a new one.

Stages of cutting tire tread

Rubber cutting service starts with tire dismantling and thorough inspection. They look not only at the permissive marking, but also at the condition of the rubber. work continues only if there is no damage not only to the tread itself, but also to other parts. the side, sidewall.

The next step is to remove all foreign objects from the grooves (trapped stones, nails) or, if necessary, carry out repair work.

The master must definitely determine what cutting parameters should be used in relation to your rubber, the scheme is selected, the depth and width of the channels is determined. It is worth paying attention to the residual depth. if it is less than 3 millimeters, then it is unlikely that repair and restoration work will be carried out.

The depth of the blade is determined by the minimum permissible depth of the canaliculus, and only after that they start cutting.

cutting the tread of solid tires for loaders and specials. technique.

Tread cutting on solid tires for forklifts and special purpose tires equipment. the service is more complicated (since the tread depth on such tires is much deeper). Cutting such tires on your own is almost impossible. This is a difficult and painstaking job that takes several hours. If you want your equipment to ride on well-cut tires, contact our service, and we will cut solid tires quickly, efficiently and inexpensively.!

If you want to reduce the consumption of fuel raw materials, increase the mileage of the tires you already have, save the budget for the repair and operation of a truck, we advise you to pay attention to a specific service, in the common people called “tire tread cutting”.

How To Determine If Your Tires Can Be Chopped! (SPECIALLY FOR SKEPTICS)

Please note that cutting the tread of tires (deepening of the tread), or simply cutting rubber, as this service is popularly called by us, is a PROCEDURE PROVIDED BY THE TIRE MANUFACTURER to extend the service life of truck tires. This service is very common in Europe, but in Russia it is just gaining popularity. Therefore, we do not recommend contacting handicraft carvers, because here skill and the highest precision are important. Do not forget that the standard tire pressure of 22.5 radius starts at 8 atmospheres. Even a couple of extra millimeters deep will reduce the life of your tire. Be sure to pay attention to the labeling from the manufacturer REGROOVABLE. This inscription is usually located on the side of the tire and means that this type of tire provides for cutting the tread of the tires. Our truck tire changer employs masters with vast experience, we have cut more than a thousand tires. and not a single dissatisfied client! If you are tired of riding bald tires, contact our truck tire service and we will cut a new tread for you.

Most often, rubber grooves are suitable for truck tires from R-17.5 to R-22.5, as well as solid tires for loaders. Slicing solid tires is another story altogether.

Tire tread cutting

cutting mud and swamp tires for 4 × 4 off-road vehicles.

This service is very popular in pokatushki lovers’ circles. Mud mixers constantly compete with each other in the cross-country ability of their cars, driving into absolutely impassable places. These cars are specially prepared, and their tires are special. There are a lot of cutting options here. There are tires already created by the manufacturer, like mud and swamp tires. On them, we simply remove some of the sipes or their parts to improve the quality of adhesion. We deliberately leave wide gaps in some places to make it harder for dirt to fill in the gaps between the sipes, making the tire smoother and less grippy. In addition, there are many different tires that are made like 4×4 jeep tires, but don’t have deep enough tread and a special pattern for really tight mud. You can buy them much cheaper, but it will be a little more expensive to cut them, tk. there is a really laborious work ahead. For some, it is possible to remove some of the old tread to create a new, deeper pattern on the tire. Some of them are generally re-cut. In general, as you already understood, cutting “mud” rubber is a creative business. And we can cut the protector according to your sketches and wishes, and according to our own recommendations and experience. Do not hesitate to call us, send photos of your mud tires, and we will advise you absolutely free of charge. How to contact us can be found in the CONTACTS section.

TREAD CUTTING

Tread cutting in Kiev

It is not uncommon for tires to wear out during operation. Buy new ones. quite a costly business. Therefore, the service of restoring the tread pattern by cutting it is becoming more and more popular. Usually, the restoration takes place fairly quickly and is done with high quality. In Kiev, many companies are engaged in the restoration of rubber. Let’s take a closer look at the tread cutting process: what does this procedure give??

What is a tread thread?

Usually a tire consists of a carcass, a steel part and a rubber itself with grooves. During operation, the protectors are erased almost completely, which makes the use more difficult and even unsafe, since there is no necessary adhesion to the ground. Rubber groove makes the tire look like new.

In the process of providing repair work, the grooves in the tire are restored by additional cutting to the technical layer. This ensures safe traction with the ground, so the tires do not slip and even at high vehicle speeds, you do not have to worry about sudden drifts on the road. In addition, the grooving will extend the tread life by about a few more seasons before having to completely replace these wheel elements. Many drivers and car owners sometimes do not suspect that they can seriously save money on buying new tires by just updating the old ones. Tread cutting service. this is a real salvation for those who are tired of paying more than necessary.

Cons of cutting the tread with a regruver

Many are very skeptical about this method of slicing, since it also has some disadvantages:

  • After cutting the rubber in this way, the tire can no longer be restored, since only about 2 millimeters remain to the metal cord. After the next erasure, you will have to change it completely.
  • If you use equipment for retreading tires in models that are not intended for this, especially summer ones, this leads to an increase in the fragility of the tire and makes it vulnerable to various damages.

On the other hand, this is a great way to thin out the tread for better grip on different surfaces, apply a new tread pattern in case of repair by means of rubber melting.

Tread cutting: working method

There are several approaches to tread cutting. This is the implementation of this process in the factory in a hot or cold way and the use of the so-called regenerator in service stations or small workshops. Let us dwell on these methods in more detail. If we are talking about cutting the tread on an industrial scale, then it happens like this:

  • The tire’s suitability for further use is assessed. Masters visually assess the degree of wear, the presence of severe damage to the frame, side parts. With the help of laser diagnostics, internal defects are determined. Specimens of tires completely unsuitable for cutting are being recycled.
  • Cutting off old tread and repairing damage. The milling cutter erases the top layer of rubber, the sides are slightly processed. The irregularities are smoothed, the cracks are filled with a product, which then hardens and makes the tire whole again. A compound is applied to the tire for better adhesion.
  • Cutting rubber using hot vulcanization or cold approach. In the first case, the surface is wrapped with a rubber band. The tire is immersed in a matrix with an increased temperature, the walls of which have a future tread pattern. In the cold method, wet rubber is pre-applied and rolled. The tire is placed in an envelope, where the layers are spliced ​​and the protectors are cut.

Another way: using equipment for cutting tire tread. regruver or its analogs. The device has replaceable attachments of various shapes. They heat up during operation and make indentations in the rubber of the desired shape, length and size. However, such a device is used only on special tires that allow you to cut the tread without harming this wheel element.

Reasons and benefits of grooved tread

Cutting the tread groove is a relatively new service for our market (it implies deepening the wheel tread to the technical layer).

CUTTING EXTENSES THE LIFE OF YOUR WHEEL BY 1-2 SEASONS

We decided to provide this service due to the fact that there is a demand for this service.

The reasons why it makes sense to cut the tread:

  • You don’t need to search and buy wheels
  • Solution of your question as soon as possible up to 2 hours
  • In winter, the wheels, after light and quick revision, literally bite into the asphalt (important for
  • minibuses and heavy transport)
  • During the summer period, it is relevant during heavy rains (the throughput of a new summer wheel is 33 liters of water at a speed of 80 km / h), drifts are significantly reduced.

Tire cutting itself. a simple process that can save you a lot of money, as well as significantly improve the quality of the most important element of a car wheel. Considering the affordable for our services, we can assume that you “acquire” calm nerves and safety on the road on very favorable terms.

Tread reserve for cutting it or which tires can be cut and which cannot

There is no point in describing all the layers and their purpose in the tire design, everything is already perfectly clear that when cutting a tire, we are only interested in the tread. Its thickness is even more accurate, because cutting will be done precisely due to it.

Scuffs by Rimblades Alloy Wheel Rim Protectors Installation Video

That is, in addition to the general idea of ​​the design, we need to know about the thickness of the layers, in particular of the tread. Let’s say right away, and we will show in the photo that a passenger tire simply does not have such a stock. Take a look at the cross section of a passenger car tire.
Between the most recessed point of the tread and its residual layer to the cord, only 1-2 mm.

You yourself understand that we are not talking about cutting grooves on such a tire. If you cut the tread in this case, then there is no doubt about the tire rupture during its operation, especially provided that the cords are cut. If this happens at speed, then you yourself understand what such savings as cutting a tire tread will lead to. It is here that the opinion arises that the tread groove is for those who are “tired of living”. Indeed, cutting car tires is not possible. And it’s not worth experimenting here.
However, not everything is as critical as it seems. Let’s say even more, there are tires that can and even need to be cut, that is, to restore the tread by forming new grooves. These are truck and so-called industrial tires. The key factor that will allow you to cut the tread grooves to the additional depth will be the increased thickness of the rubber layer of the tread. This is what will allow you to cut grooves again. Typically, these tires are marked. regroovable. Anyone who knows even a little English can easily guess that in fact this word hides in itself three others (repair, groove, ability). Kind of like the ability to restore tread grooves.

That is, even the manufacturer has laid such a possibility, which means that in this case, when cutting a tread on such tires, everything will be fine.

The only thing is to comply with some conditions. They are again obvious and simple:

This is, if I can say a short list of recommendations, but in order for you to understand what, how and how much, it is better to familiarize yourself with the cutting process in pictures. Then you will not only hear and read, but also see for yourself, and most likely understand how to properly cut (restore) grooves on the tire tread.

Cutting tires with a groover, is it possible and safe!?

Many people have the opportunity and desire to save at least something and at least on something. In some cases, this is influenced by the general financial situation, and someone saves on the principle of koshchei, sort of because he is just a curmudgeon in itself. Is our economy always justified and isn’t the proverb that the miser pays twice if you try to save on tire cutting !? Rather, on the contrary, on cutting them again and not buying new ones! This is what we will talk about and try to give answers in our article.

But first, before we talk about the cutting process and how and when it all appeared, let’s take a look at the typical tire design by layers in order to understand how much the surface layers can be weakened so as not to lose strength, and as a result, in safety After all, it is the safety issue that is most relevant when cutting a tire, which is a matter of course. After all, cutting off its layers leads to the fact that the stiffness of the tire and its strength change, while not for the better.

Why cut a tire tread?

So, back to the main topic of the article. All that we wrote to you above is not just idle curiosity, this is one of the completely legitimate ways to extend the life of tires on a car. Using the tread groove, you can extend the service life, or rather the mileage, by 20-25 percent. Agree, not bad, given that tires are not so cheap, especially truck tires. Here, another opinion may also arise, why actually cut the tread again. If there is a reserve, then you can simply drive on these tires until they wear off to the tire cutting indicator. However, this opinion is criminal, because in such cases the tire will resemble a slick profile, that is, it will have the maximum contact area with the asphalt, but however, any ingress of dirt or water will lead to aquaplaning, which means loss of control. The liquid medium will not be squeezed out into the grooves, and then from under the tire, as a result, it is possible that there will be some kind of lubricant between the tire and the asphalt. As we have already said, this is fraught with skidding, sliding, loss of control. That is why if the protector is worn out, then there are only two options. Either restore it, or change the tire to a new one. You shouldn’t just neglect this fact.

The process of cutting, retreading the tire

We haven’t told you anything about the equipment, but we won’t. Our article is not about this, and is for informational purposes only. We do not think that you will go for such a device, since this is done at the service station, and they do not need our stories. Let’s say very briefly that in fact the cutting machine is something like a wood burner, where the cutters change, and the cutter itself is sharpened and warmed up during operation.

So, a cutter is selected along the tread profile, which we will cut and install in the clamps.

In this case, the height, or rather the depth of the cut, is set according to the template. the caliber. After that, the cutter is fixed with fasteners. Turn on the device and let it warm up.

Then we cut in the direction of the tread groove, which we want to restore. In this case, the set of the cutting depth occurs automatically, due to the fact that the platform. the limiter does not allow cutting more than what is set. In this case, the platform itself, it is necessary to drive along the surface of the tread, pressing it all the way.

So, over and over again, groove by groove, and a new tread is cut. After cutting, it may be necessary to remove the rubber with your hands, but this is easy to do. The cut groove is simply removed from the tire and that’s it.

Summing up on tire tread cutting

Summarizing the information on tire treading, we can say that this is not just an unreasonable and risky economy, it is a normal and pragmatic behavior. This procedure allows you to extend the life of the tires, while it is quite “legal”. If everything is done according to the recommendations and without violating the technology, then the tires will last longer and their characteristics will not suffer. This only says one thing, that cutting tires is good and justified, but if someone says that it is not permissible, then such people simply do not have complete information about which tires can be cut and how to do it correctly.

A bit of math

When buying, for example, a used winter tire with a grooved tread, the driver gets a residual groove depth of 6-7 millimeters. And up to the 4 millimeter mark, which is allowed by the rules of the road, he still has to drive and drive. But in fact, it turns out that the residual thickness of the tread rubber compound is only 1-2 millimeters, and therefore very soon the tire will become unsafe.

The situation is identical with summer tires. Only the reference point for critical wear is here with a residual tread depth of 1.6 millimeters. Accordingly, when buying a pre-cut summer tire with a residual tread depth of 4 millimeters, a layer of rubber compound that will provide good enough grip will end after 1 millimeter of wear.

Tread cutting on passenger tires is absurd. And buying used tires is not a healthy economy, but a game of luck: 50 to 50, lucky. not lucky. Remember: the car rests on the road with only four points, the contact patch area of ​​which does not exceed the palm area. And a tire that “fired” at speed can cost life not only to the person who embarked on an adventure, but also to the people around.

How to recognize slicing

The first thing to look out for are the wear indicators, which are usually located at the bottom of the groove. Chopped tires simply physically cannot have such indicators, since the bottom of the groove has been punched. That is, this indicator was cut along with the rubber layer. Finding the place where this indicator should have been is very simple. It is enough to look at the sidewall of the tire and find there a special marking “TWI”.

The second sign of a grooved tread is the non-straightness of the edges and different depths of the tread grooves.

Why cut a protector

Grooving a tire is a groove or groove in its tread. The grooves are responsible for the effective drainage of water from the contact patch and prevent aquaplaning. Also grooves allow better grip on non-hard surfaces.

Cut only those tires with the “Regroovable” mark on the sidewall. It can be found on truck and light truck tires. In order for the tire to allow cutting of the tread, the manufacturer uses additional layers of rubber compound in the tread section and reinforces the carcass. But it is strictly forbidden to cut a pattern on passenger tires.

Why pre-cut used tires are beyond reason

The tread can only be cut if the tire is marked “Regroovable” on the sidewall. And there are such markings on truck tires and tires for light trucks. On passenger tires, it is not. But that doesn’t stop garage dealers and used tire sellers. In a new article by the company “Autoset” we tell why those who cut the tread of passenger tires are wrong. Your attention is a video and its text version. choose a format convenient for you.

Who cuts the tread and how

Most often, sellers of “beushki” sin by cutting a tread on passenger tires. Using the regruver, a special tread cutting tool, the residual groove depth can be easily increased from two to five millimeters. And a used tire with a 5 mm tread looks much more interesting in the eyes of the buyer than a tire with a 2 mm tread.

But does a chopped tire retain its performance characteristics? No, because the tread layer has practically worn out and the “plastic” sub-tread layer is in contact with the road. There is simply no need to talk about effective braking or good handling. This is especially important for winter tires, because some manufacturers place the tread layer almost immediately at a depth of four millimeters.

The strength of the tire will also change, since the unevenness of the road will be perceived by the carcass and breaker without cushioning by the tread layer. Plus, a rock hitting directly into a freshly cut groove can puncture the tire, tearing the breaker and carcass, and at high speeds, centrifugal force can destroy the wheel. In addition, if the tread on the tire is cut in different sections to different depths, this can seriously affect the balance of the wheel, which means it can put additional stress on the car’s suspension.

Passenger tire construction

If you look at the tire in cross section, the first layer will be the hermetic layer. He is responsible for the tightness of the tire. The second layer is the tire carcass. It consists of woven synthetic threads immersed in a rubber compound. Most often these are nylon threads. It is the tire carcass that accounts for the weight of the car, passengers and luggage.

The third layer is the breaker. It consists of tough, twisted steel strands. It is this layer that provides transverse rigidity and longitudinal flexibility. So, under the action of centrifugal forces, the tire can be stretched, but thanks to the breaker, it will keep the contact patch with the road close to a flat. Also, the belt retains flexibility in the vertical direction, which allows the tire to bend around obstacles, as it were, transmitting shocks and vibration to the car to a minimum.

The next layer is a nylon bandage. It prevents tire deformation. On top of the bandage there is a protective layer. Its rubber compound is very different from the top tread layer. It is more rigid and similar to plastic. The difference is due to the fact that the tread layer determines the ride quality of the tire, but the tread layer is needed in order for the tire to better retain its shape or more reliably hold the stud. Another reason why manufacturers use different rubber compounds in the tread and tread layers is the desire to save money and offer the buyer a competitive price. And absolutely all manufacturers do this, from the premium segment to the budget one. Another thing is that the thickness of the cheap, sub-protective layer is different for different models.

Regruver for cutting a tread with your own hands

Self-made device for cutting a tread on a tire (regruver) with your own hands.

I wanted good off-road tires for the summer, but not very noisy, I wanted something in the A / T style. Looked at the for my size 215/65/16. about twenty thousand per set!
Now there are no such days! Regular new road tires cost about 12 thousand rubles, and if you find used tires, then from 3 thousand rubles. per set!
I compared A / T tires and road tires and understood the difference only in the tread, or more precisely, in the number of transverse cuts and the width of the cuts! On off-road tires there are more transverse slots, the width of these slots is larger, there are no longitudinal slots and, most importantly, side soil hooks!

I watched several videos, with the help of a regruver cutting machine, they change the tread pattern and realized that this is what I need! I looked at the for Regruvers and was also a little upset! The cheapest 10t.r., And the normal 20tr.

Without hesitation, I decided to make this regrover with my own hands.

I just had a non-working microwave, I pulled out a transformer from it. I removed the secondary winding and wound a thick copper wire instead. There were not many turns of the secondary winding, about four.

First, I tested a homemade device on an old tire, almost bald. It is best to cut on an inflated wheel and draw the cut lines in advance!

Also cut a new tread on a bald winter tire. With the help of a regruver, you can cut any pattern on an old tire. Of course, it is better not to ride on such tires on the highway, but such tires can be used for off-road trips. Thus, you can make tires for a homemade buggy, mini tractor and other homemade equipment.

How to determine if your tires can be grooved and tread groove technology

Please note that the groove of the tire tread (tread groove) is the tire manufacturer’s procedure for extending the life of special vehicle tires. This service is very common in Europe, but in Russia it is just gaining popularity. Therefore, SkyTech does not recommend turning to artisanal carvers, since skill and the highest precision are extremely important in this process. Be sure to pay attention to the labeling from the manufacturer Regroovable. This inscription is usually located on the side of the tire and means that this type of tire provides that tread cutting is possible. Tire tread cutting is an increase in the grooves and channels of the tread by removing a small layer of rubber without reducing its basic properties. The result is achieved due to the specifics of tire design. at the development stage, a “gap” of several millimeters is provided, which allows you to deepen the tread without losing the strength and integrity of the coating.
Not only new tires can be cut, but also reconditioned ones, the main requirement is a special marking that allows such manipulations. If your tire has a U badge or Regroovable inscription, then you can safely contact SkyTech for a similar service. It is not worth experimenting. cutting rubber onto a forklift is a responsible task and making indentations on your own, without experience and skills, is not only unreasonable, but also unsafe. An improperly processed tire can lead to irreparable consequences at any time.
