Zalishkova little tread height. Permissible tread wear. What is the tire tread

Height (її also called depth) of the tread(About the big track of the tire) - tse stand in the bottom of the water ditches to the surface, as if in direct contact with the road. The given value may be different in the middle of one specific tire - the height in the center of the tread may not increase with the height in the shoulder areas. Therefore, the height of the tread must be measured there, de є, by a vibrator.

The height of the tread also carries in itself a functional boost of the tire itself as a whole. Yakshcho, zgіdno z vznachennyam, tread - an element that protects the inside of a tire, That, working with the height of the tread, the treadmill creates many little ones and forms a system of water channels, giving the tread the necessary characteristics.

It is not surprising that the height of the tread of new tires, presented on the market at the same time, is different. Ale krіm p_dhod vyrobnik іsnuyu і іnshі factori, scho vplyvayut on the height of the tire tread:

seasonal

functional

Also, remember that for the tread of new tires, only one value is fixed - the minimum permissible height of the tread. Tse means that there is a standard for the height of the tread only for tires that were in the vzhitka. This standard is the minimum allowable boundary, lower than any vikoristovuvati tire is fenced. On the territory of Russia, the minimum permissible (oversized) tread height is 1.6 mm, and - 4 mm.

Tread height

The presence of a limit on the height of the small big track in new tires allows tire manufacturers to actively work with the other elements of the tire - gum sums and internal bud to achieve optimal tire characteristics. Therefore, the value of the height of the big track can give a positive impact on some characteristics i, at the same time, a negative impact on others. So, for example, a tire with a high tread, and therefore, with deep water channels, will effectively bring water in, but at the same time it will be easier to cope with. A deadly situation with a tire, for some little treads, it may be even more daily - with a slick tire. In this case, the tire will demonstrate excellent curing, but it will be absolutely harmless on the road with minimal falls. Therefore, a robot with a tread height is designed by tire engineers only in combination with other elements of the tire, which allows improving the tire's performance without reducing other indicators.

A good butt of such a mutual modality is tire mileage. On the cob period, the use of tires with a tread, the very height of the first potential run. I, the bigger the tread, the greater the number of gums in a new bulb, which means that the greater number of kilometers the tire could pass. At the daily stage, the size of the test is determined by the storage of the gum sum and the recipe of the compound. Therefore, it is not varto to focus on the height of the tread, as on a single indicator, which indicates the value of the potential tire mileage.

It is necessary to say that the height of the tread in one and the same range, but in other manufacturers, can be adjusted, which is considered to be a technical and technological level of a leather company, as well as the approach to the opening of the tire. The tread height of one model can also change from size to size, and a larger indicator, as a rule, will be for narrower sizes.

Tread height

The collection of water can be used to increase the amount of cover, the lower inlet. The road covered with ice and snow, snow porridge or a chemical reagent will reach dry and wet asphalt. Most of these coatings affect tires galvanized system of water channels and pressure blocks of the tread To improve the negative profile of the tire (the total expansion of the tread channels), as well as the improvement of the tread height. Crimson, the need for reinforcement of spikes also means a protector with an increased height. Do not forget that the minimum allowable tread height for winter tires is significantly greater than the river limit (4 mm versus 1.6 mm). Everything to bring to the fact that the tread of winter tires can be very high(Abo glybin) tread.

Tread Height:

Zimova studded tire 9-10 mm

Zimova non-studded tire 7.5-9 mm

- river road tire 7.2-7.8 \u200b\u200bmm

The height of the tread should be determined by the recognition (function) of the tire.

Tires may differ in recognition, so as to use different cars, styles of water, different types of coverage and the frequency of changing on these coverages. Not surprisingly, tires for different victories also have different tread heights.

Tread height of summer tires:

Road tire 7.2-7.8 \u200b\u200bmm

Sports tire 6.5-7.5 mm

- tire for commercial vehicles 8-10 mm

Pozashlyahova tire 13.7-14.7 mm

Sports tires change the size, lower quality road tires, tread height for the shortest indications of keratinization.

Commercial tires are reinforced with a higher tread, which allows them to wear more rubber, And that means more high resource. The creamy, deep little tread allows you to effectively practice the position of the asphalt pavement.

Tires for road trips with leaders in tread height So, as the tires become more aggressive, and the height of the tread is great to help protect the tire from the road. Krіm tsgogo, otrimaniy as a result of the increase in the height of the tread, to improve the efficiency of the work in the mud, on sand and other unstable surfaces.

In a visnovka, varto, it means that the height of the tire tread will help three times the difference about the recognition of the tire and її seasonality in the middle of the proposition of one tire. Ale choose tires, focusing on the whole display, not varto. So like a tire is a foldable product, and only a tread without a face put in front of a tire does not viide.

For the wealthy car owners at least once, the thought came to save, and “transport” their car not in new tires, but already in vzhitku. Until then, the sellers zapevnyayut that the wear of the tires is minimal. In practice, it appears that it would be possible for the gum to live in a zhalugidny camp. Wt_m, and new tires are often not ideal. From the statistics you know what kind of glide and tread height of a new winter tire may be.

The tread is called the outer ball of car tires, as it sticks to the roadway without intermediary. On the same part, a special baby was created, which is made up of bulk elements and grooves of the singing depth and straight lines. Iogo recognition - to ensure the maximum connection with the surface of the road, to effectively introduce snow and water into the contact between the wheel and the roadway.

It is obvious that the amount of wear and tear of the ovniy ball without intermediary flows into the stability of the machine, its throughput and keratinization. In addition, the reliable operation of the galmive system is also impossible, as the wheels are very worn.

Video "How to independently determine the height of the tire tread"

From this video you will know how to measure the height of the tire tread without vimiryuvalnyh tools.

How to win the tread depth

Regular monitoring of the height of the excess small winter tread, as well as timely replacement of the gum until the wear reaches a critical value, allows you to minimize the risk of emergency situations.

You can win the comradeship of the global gumi ball in dekilcom ways. So, current instances are provided with safety indicators that control wear and tear: as soon as the tovshchina ornament reaches the minimum allowable value, its obviousness seems to be on the ability to control the machine, and water of reason, it is the responsibility of remembering the gum. Sometimes, in the guise of a kind of display of the necessary swede, replace the tires with vicorist and color balls of gumi - just like a little stink on the surface of the tire, it's time to see a tire service.

For more precise control of clay, professionals will install a special tool - glybinometer. Ale dosvіdcheni vodії know that you can do without it, floating under the hand of a great coin of 10 kopecks. We insert it with an edge into the groove of the ornament and evaluate the result: as if “copies” were written more than once, your tire is in excellent condition; just like a guma, it only distorts the growing ornament, you can ride on wheels, but you can get ready to change the tires; as if there was only a rim in the bore, change the wheels negligently.

For a more accurate picture, we should carry out along the entire stake of the wheel. How to show up, that in different stages of wear and tear of tires, it is necessary to violate the service station and regulate the installation of wheels.

Required tread height for new tires

The height of the little one of the winter ball of winter gum is required in the fallow land depending on the factors: the type of car (passenger, vintage, passenger), yoga category, climatic minds of the region, etc.

“2.3.2. The height of the little tire is guilty of buti no less:

2.3.2.1. For transport zasob_v category L - 0.8 mm;

2.3.2.2. For transport zasob_v category M1 - 1.6 mm;

2.3.2.3. For transport zasob_v categories N і O - 1.0 mm;

2.3.2.4. For transport zasob_v categories M2 and M3 - 2.0 mm;

2.3.2.5. For prichepіv (pіvpіvpіvіv) - the same as for tractors, with yakim stinks pratsyut.

2.3.2.6. For winter tires, as well as those marked with the sign "M + S" - 4.0 mm.

allowable wear

On vіdmіnu vіd vіd lіhіh іrshok, zimovі pridatnі before exploitation only 2-3 seasons. Further, the little tread wears off the flooring, which makes the operation of the car unsafe. The PDR hangs specific vimogi and up to the outlying clay of the little one, in the fallow land according to the type of transport problem (edition of the SDA 2018 rocky):

“5.1. The end depth of the tire tread (with the presence of wear indicators) should not be more than:

for transport zasobіv category L - 0.8 mm;

for transport facilities of categories N2, N3, O3, O4 - 1 mm;

for transport facilities of categories M1, N1, O1, O2 - 1.6 mm;

for transport zasobіv category M2, M3 - 2 mm.

Do not save money on high-quality safety, and easily put before winter tires. Seeing them, I will often lay aside the life and health of passengers.

Be drunk, no wand, no flowers!

Why go out? Clause 2.3.4.4. Installation of tires of different sizes, designs (radial, diagonal, chambered, tubeless), models with different tread patches, frost-resistant and non-frost-resistant, new and renewed, new and with a worn-out small tread on one entire vehicle. - Can you stop working?

From the technical regulations it is not possible, but it is taken as an addendum to the DA (clause 5.5. Transfer of faults)

Changes were bumped into vintage cars with a permissible maximum weight of up to 3.5 tons, then vintage cars of category B. Previously, on such cars, the guma could beat up to quiet pir, until 1 mm of tread was lost. On September 1, 2013, trochs will be more hardy - 1.6 mm. For example, small investments (Gazelle, Mitsubis L200, Volkswagen Amarok, etc.) can be bumped into.

A pardon in the text: From the 1st of September 2013 to the year .... All the same, I think it’s on the vow "On the 1st of September 2015 to the year"

Is it possible to beat the summer gum in the winter period, so that the road surface is not frozen and not covered? At Krimu, the temperature is mostly positive and without snow.

It's possible, it's possible. I want to go to Crimea, I want to go to Vorkuta. Golovne shob buv vikonany point:

There is no blame for the spare wheel. Yakshcho zupinyat - fined. Because you have a spare tire that fits into other wheels, then beat it as much as possible (just go straight to the nearest tire fitting).

This point is easy to understand, especially if you do not read the document in full.

Summer tires are ventilated in winter tires with greater hardness. The material is very flexible, which ensures the necessary coefficient of adhesion to the surface.

Number of treads on a new summer tire lie in the form of a vehicle: for a passenger car, the indicator should be 7.5-8.5 mm; for vantazhivok and pozashlyahovikіv nebhіdna guma z indicator 12-18 mm; for self-skidding wines and can be up to 23 mm.

Guma can sense remember, If the depth of the recess of the tire of the "passenger car" changes to 2 mm. And in some countries, the allowable tread of summer tires is 3 mm.

Wimogi up to the height or depth of the tread can be placed in the 5th PDR of the Russian Federation. And the level of wear and tear of the details is shown in the "Translation of inaccuracies and minds, in which the exploitation of TK is defended." Zgidno with documents, excess tread of summer tires for different types of cars: motorcycles - 0.8 mm; light cars and vests weighing up to 3.5 tons, halyards to them - 1.6 mm; vantage machines larger than 3.5 t - 1 mm; buses - 2 mm.

• asymmetric. One lot of the tire of appointments for the security of the security, the other one - for the water supply. On such a gum you can ride fast and not be afraid of a wet road, kaluzh, brud. The only small one is a high price.

Read the report in our article about the features of the tread of summer tires and the rules for their selection.

tread features

Summer tires are ventilated in winter with greater hardness, so they are recognized for safe driving on hot or wet asphalt, in free in ice and snow. The material, from which they are prepared, may have a high thickness, which ensures the necessary coefficient of adhesion to the surface. Є tsіliy row vymog, yakim vinni vіdpіdat іtnі tires:

• resisting wear and tear, which is possible for the account of their hardness;
• security of car damage;
• yakіsne zcheplennya with the road;
• the fight against aquaplaning, so the machine is not guilty of “weaving” on wet surfaces, enough to move the trajectory through the water.

clay

The relief of the automobile humi is not equal, there are depressions and bulges on it. The stench is due to the mother of the singing parameters. Otherwise, the wheels are worn out, and the car is out of order. An important indicator is the tread depth of summer tires (height). It is the standard for the skin type of transport, more precisely, the obmezhennia after the gum erasure level. If it is more than allowed, it is no longer possible to travel.

When buying a car, it is important to know what kind of tread a new summer tire has, so that it does not happen to be changed. The number of deposits by type of vehicle:

• for a passenger car, the indicator should be 7.5-8.5 mm;
• for vantage and pozashlyahovik it is necessary to have a gum with an indicator of 12-18 mm (why is it more important and can the car be more important, the height of the tread of the summer tires is more to blame);
• as a language about self-skids, more or less - up to 23 mm.

Itself such a mud to ensure a good connection with the road, including wet. Zapadini vіdvedut water, and the machine does not spend stamina.

Motorists need to be aware: as the minimum tread of summer tires is 1.6 mm, it doesn’t mean that you can bring them to such a state. To that, the less clay, the lower the coefficient of adhesion. But with important weather and road minds, it can become unsafe.

A car with mayzhe "fox" tires is less stable, more galmuy. With a sharp protrusion, yogo can be entered in the book. Guma may be sensible to remember if the depth of the “passenger car” tire trap changes to 2 mm. And in some countries, the permissible tread of summer tires should be no more than 1.6 mm, but 3 mm.

expert's thought

Nadia Smirnova

Automotive Law Expert

Virishyuchi, if you replace them yourself, you need to wonder, for some surfaces you often have to travel. Even on a worn-out gum, you can not only spend it in an accident on the road or on wet asphalt, but you can easily get stuck on the dirt. Її brilliance and novelty are added to the passability of the car.

What laws govern

Wimogi up to the height or depth of the tread can be placed in the 5th PDR of the Russian Federation. And the level of wear and tear of the details, which does not allow the use of a car, is included in the "Translation of inaccuracies and minds, in which the operation of TK is protected." In both documents, it is indicated that the excess tread of summer tires for various types of cars is to blame:

• motorcycles - 0.8 mm;
• light cars and vests weighing up to 3.5 tons, halyards to them - 1.6 mm;
• vintage machines over 3.5 t - 1 mm:
• buses - 2 mm.

This pokaznik is normally guilty of buti higher (Vdpovidno, the level of wear is lower). For damage to water, check the early warning for part 1 article 12.5 of the Code of Administrative Offenses:

Carrying out by the transport safety in case of manifest faults or minds, in case of any faults, it is possible to comply with the Basic Provisions on the admission of transport faults to the operation of the landing gear for the safety of the road traffic, the operation of the transport fault is fenced, due to the faults in , pull behind you in front of you or impose an administrative fine of five hundred rubles.

tovshchina

Such a display, like the tread of a summer tire, PDR or "Faults of faults ..." is not regulated in any way. Ale on the gum, which victorious in the heat of the time of rock, ring out the vuzzle grooves and wide bulges with slits. Stay and take good care of the road.

Tovshchina vlasne tread to lie in the sight of tires. Vaughn can vіdrіznyatisya through the type of baby. But there are no standards here, more precisely, the stench is used for picking up details. Vodієvі for comrade's stitches are not brought, shards won't change during operation.

See summer gumi

Іsnuє k_lka types of tires, recognized for vikoristannya in the heat of the time of rock. Їх to dilyat fallow in the form of a little one. On the right, not only in purely ovnishnіh vіdmіnnosti. All kinds of treads of summer tires may have advantages and disadvantages:

• symmetrical. This is a classic option and therefore universal, wanting to drive the most on asphalt roads. On such tires, the bits of the little one are the same. Guma may be averagely enduring, it is her fault to win over the most important on the poorest swedes. Stay especially important on turns and in rainy weather.

Aquaplaning to finish the garne, but on the way, in the mud, the car could stall. Plus classic tires - low price.

• asymmetric. One business of a tire of appointments for the safety of security, and another for water supply, to that the stench sounds like. On such a gum you can ride fast and not be afraid of a wet road, kaluzh, brud. With her, cars become more stable. The only small one is a high price.

And the tires for the right and left wheels are blown up, even if the outer side is not to blame but in the middle. It didn’t make sense to him, like a “reserve” to buy and carry with you. Don't guess at the end of the day, right or else the wheel will appear pierced.

When installing, it is important to point out the small tread of summer tires directly. For a correct installation, look at the “Rotation” icon and the arrow, as if showing how the wheels are spinning. So mark the tires with the direction of the little one. It is also asymmetrical, it is necessary to write the letters Outsaid (“outer side”) and Inside (“inner side”).

If the tires are not installed correctly, the car becomes less auditory, which increases the risk of an accident. Until then, the gum will sooner come into obscurity. Directly, the little one can not be fooled, as if the tires are symmetrical.

About those, how and how summer tires choose, marvel at this video:

How to determine the wear of the tread

As the gum has been victorious for a long time, it has been worn out a lot, it is possible to point out the need to replace it by eye. But all the same, the wear of the tread of summer tires is greater than the superior method of installing the first stage. You can die for additional coins, having placed in the grave. Potim її apply to the line or a tape measure, to determine the height of the tread. Freeze at least at 6 different points, and more at 9-12.

Sometimes the surface is erased unevenly, which can be evidence of the incorrect operation of the car:

• the height of the tread is less in the middle, which means that the wheel has been pumped over for a long time;
• the indicator is higher in the center - in tires, navpak, too little more, next to pidkachati;
• one of the edges was erased less, later, there is a problem with pіdvіskoyu;
• on all surfaces the depth is not the same - the wheels have been tested many times for extreme driving and sharp galvanization.

Like a bi akіsnim and bright camp, not a tread of summer tires, at the cost of no lawful behavior on the road, neatness. First of all, in Russia, the rule was to protect the special features of the cover. And the collection of the car is obov'yazkovo required to "re-call".

Zimova avtomobilna guma is looking after the material- m'yaksha, through which the car is not forged, it is ensured that the wheels are well connected to the surface. Hydroplaning cannot be allowed, the stench is to blame for the safety of the ride, like a galvanization. With tієyu, I’m using the method to sting them with spikes.

Another special feature is the greater number of lamellae, that is, transverse cuts in the swells. Stink zbіlshuyut stіykіst car. The characteristic feature of tires is a deep tread.

Minimum height of new gumi- 8.5-9.5 mm. Vaughn to ensure a good stability of the car in the cold season of rock, as if the road were open. For larger folding minds, it is possible to tread the protector of 9.5-11 mm. For off-road, it is better to show the indication of 12 mm. Use also tires with 15 mm tread.

Winter tire tread features

Automotive huma, recognized for cold weather, it looks like summer according to the material rich in other signs. Winter tires are more soft, even if they need to be in contact with snow, crying on the road or frozen asphalt. Zavdyaki tsomu stench not to let the car kovzat, secure well zcheplennya kolіs s surface.

Hydroplaning should not be allowed to cause frequent contact with the road. Winter tires are responsible for ensuring the safety of the ride, like galvanization. With this method, they sting with spikes, although it’s not obov’yazkovo.

Another feature of the winter gumi is the greater number of lamellas, so that there are transverse cuts in the swellings. Stink zbіlshuyut stіykіst cars. The characteristic feature of tires is a deep tread.

Visota

The winter gum looks more thick, strained. Vlasne, how to shy away the term її vikoristannya great, lower in summer. The height of the tread of winter tires can be different, so as to lie down in any type and size. Age and diameter of car details are not the same for all TK.

The minimum value of the indicator, which is like a language about the new gumi, is to blame for becoming 8.5-9.5 mm. Vaughn to ensure a good stability of the car in the cold season of rock, as if the road were open. For larger folding minds, it is possible to "sound" yoga in a tire with a tread of 9.5-11 mm. Such guma is popular in Russia. For off-road, it is better to show the indication of 12 mm. Use also tires with 15 mm tread.

clay

The outer part of the automobile gumi may look like rows of depressions and bulges. This is the reason for understanding "the depth of the tread of winter tires." The term vikoristovuєtsya in normative acts, scho avenge vimogi to become TK. Ale, in fact, is the height of the tread. Adzhe expanded the swollen part of the tire to an older size, adhering to a new death. The language is not about gaps on the blocks, but about the highest and lowest points on the surface. New winter tires due to mother glybin 8.5 mm.

little ones

Another sign that characterizes winter tires is a small tread. In the cold season, on the road, there can be ice, ice, snow, wet “porridge”, and hardened asphalt or soil. The little ones are chosen, mindless, in some cars they are used more often.

It is important that in Russia the gum was as close as possible to the surface, it led the country to the spiky kolіs, it changed the slippage on the swidkost and sovіlnenogo galmuvannya. It’s impossible to eat all the yakos in one type of little one, that’s a sprat:

• straightening. All the paths are marked with V-shaped signs, but at the upper point of the line the depression does not converge. Such tires are good to walk on the surface of wet snow, as if they lie in a thin ball, dry and wet asphalt. Ale not varto їhati nadto shvidko.
• symmetrical. Buried with a wedge, like a front slope. Ale on the tops of the stench converge in one point. These little tires ensure good adhesion of cars on wet roads, as well as on dry asphalt. The stench is designated for a tightly tidied winter track, to give the opportunity to increase security.
• asymmetric. To unite the advances of the two previous types of the little one. To that tire vikoristovuyut for important snow roads, as if you had to go to the lake. Ale, not varto, overdress too quickly.

See the winter gumi

Winter tire tread with different types of performances in offensive types:

• vulgar. The little ones are often straightened and V-shaped, and the depth of the depressions reaches 11-12 mm. It’s better to vikoristovuvat such a gum there, de rich in snow, more like a necklace. Andzhe on the wet asphalt, it will make a lot of noise through the surface of the rubbish, as well as the greater vitrata of the fire. With zashlyahovymi tires you can’t get in the way of swidko rozіgnatisya and galmuvati.
• shvidkisny. Tsey kind of gumi sound maє directions of little ones and a shallow protector. Vaughn is recognized for travel on the vіdkritіy dorozi, so it's better for the peace climate, vikoristannya in the boundaries of the place. But don't be afraid of a small snow, wet surfaces. Shvidkish tires have a short galvanized path, you can go fast. The noise level is low.
• classical. Buvay with directing and non-directing little. The tread of these tires should be deep enough to overcome snowfall, but not due to impassable roads. It is best to "wear" them in the city, the riders on the dead coat.
• Asymmetrical. The outer half of the track of these tires is proven to be in good contact with a clean surface, the inner part helps to repair the snow porridge. Aleshvidka їzda z such a guma nebazhan. "Take" the car in them, if you have any minds, do it enough galmuє, you can bring it in.

Most of the cars in the pivnichnyh latitudes wink with the classic variant of tires, deyak - with pozashlyahovim. The fashion is coming in and recently asymmetric ones have appeared. But stinks are not cheap, and their effectiveness in Russian minds is questionable.

Permissible tread charge

The wear of those winter tires is still inevitable. І it is important to remember them every hour on new ones, so that you lose control of the car, accidents. The permissible tread of winter tires can be:

• according to the wear indicator applied to the humus;
• Vіdpovіdno to the DA.

For the first person, everything is simple. When erasing the tires to the badge, which is buried, otherwise the badge-snіzhinka of them needs to be changed. Ale, before respect, take the road mind, in which the technique is mastered. It’s like having to travel fast on the filthy cleared snow, ice, rather don’t check, until the gum is called to be vented.

Minimum and excess wear of winter tires

For the presence of the indicator, the oversized tread of winter tires is not guilty of overestimating the value. The term itself establishes a value that cannot be less than that. The information is provided in clause 5.1 "The transfer of faults and minds, in which the exploitation of TK is prevented":

Kіntseva glybina small tread of winter tires, recognized for operation on an icy or snowy road surface, marked with a sign at the top of the mountain top with triple peaks and a lower mark in the middle of it, as well as marked with signs "M + S", "M & S", "MS" (with the presence of depreciation indicators), for the hour of operation at the designated cover, become no more than 4 mm.

Even though the law permits the minimum tread of winter tires is still not a guarantee of safety. It is better to innovate the gum, until it has reached the limitingly permissible level of erasure. For example, for custom-made tires, changing the depth to 4 mm is not uncommon, it is difficult to turn a car with such changes. Aje tse means that the protector of relations is greater, lower by 50%.

Yak vyaviti demolition

The critical level of erasing gum without an indicator is important until it shows up on the features of the ride. Winter tire tread wear is more accurately controlled by a caliper. Yogo is placed in burial in dekilkoh roztashovanih far one in one point. It is important to vrakhovuvaty, the tovshchina hurried to the skies, in some places, as the numbers are quivering:

• a large level of wear in the middle of the tires means that the wheel is overinflated;
• well, but at the edges to tell about the lack of a povіtrya in them;
• Irregularities on wheels can be seen by all counts as a lover of sharp galm and gas;
• erasing one of the edges of the tire means that it is necessary to change the suspension.

It is especially important to choose the right winter humus, to control this camp. Otherwise, the ride threatens to become extreme, including for other participants in the movement. Do not varto throw off rakhunkiv and those who have been fined for the “fox” tires.
