Car tires have cracks, do you need to change them?

If the car tire has a little crack, judge whether the tire needs to be replaced according to the following method:

1.The outer edges are worn.

If you look in the direction of travel, there is a large amount of wear on the outside edge of the tire, indicating that the tire is often in a state of insufficient inflation, that is, the pressure is insufficient. If possible, inflate at the "highway" standard, i.e. add another 30,000 pascals to the normal standard. It is important to know that under-inflated tires are very unfavorable for driving in rainy conditions, and the grip will be significantly reduced.

2.Convex and corrugated wear.

If it is found that the two sides of the tire landing part are convex and worn, and the tire perimeter is also corrugated worn, it means that the shock absorber, bearing and spherical coupling and other parts of the car are seriously worn. It is recommended that you check the suspension system for wear and tear before replacing the tires. Otherwise, even changing the tires won't help.

3.The surface is evenly worn.

Once the tire pattern has been worn dry, it means that the life of the tire has reached the end of its life and must be replaced. In addition, the pattern also has the effect of draining the water on the road, so it is an important part of maintaining the grip of the car. If the wear has reached the standard depth of the tire pattern (usually mm, or 2 mm for tires with a width greater than 175 mm), it should be replaced.

4.The center part is worn.

If you notice severe wear on the center area of the tire's landing section, it is a sign that the tire is often overinflated. Be sure to check whether the pressure gauge is accurate, adjust the pressure, and know that you only need to overinflate the tires when driving at high speeds or heavy loads.

5.Wear on the inside of the tire.

The inside of the tire is worn, and the outer edge is burr-like. It is common to see some old cars with poor suspension systems, which sink the entire body. This indicates that the tyre is deformed and the symmetry of the two tyres has been compromised.

If possible, it is best to replace all the shock absorbers, spherical couplings and other accessories. However, if the cost is too high, you may want to ask a professional mechanic to adjust the angle between the front axle and the tyre.

6.Cracks on the side of tires.

This is often caused by poor maintenance, or driving on rocky roads and construction sites, so that hard objects come into contact with the tires, causing damage to the inner layer of the tires under heavy pressure. Immediate action should be taken, and if the repair is not good, the tire should be replaced.

If there is a crack in the tire, it depends on how deep the crack is, and if the crack length is less than 6 mm, you can go to the repair shop to repair it. Otherwise, the tires need to be replaced. If the repaired tire is the front wheel, it is recommended to swap it with the unrepaired rear wheel to minimize the risk of a puncture.

In some remote places, you can't find a repair shop nearby, and if the tire is cracked, you can replace the spare tire, which is safer.

If there is a crack in the car tire, it must be replaced to avoid unnecessary accidents.

When a car tire is used for about 4 years, fine cracks will appear on the surface of the tire. The rubber on the surface of the tire has aged to a certain extent and will peel off from the carcass when subjected to external force. When aging to a certain extent, the rubber part of the tread may suddenly fall off.

Combined with the national conditions, the service life of car tires is about this: the safe driving signal mileage is about 80,000 kilometers, and the life is about 5 years. The age of tires is not very long, so when buying tires, you should pay attention to the production date and buy "fresh" tires as much as possible.

There are many reasons for tire cracks: length of use, poor driving habits, road surface causes (abrasions, scratches), natural aging or cracking of tires, the quality of the tires themselves, etc. Whether or not a tyre replacement is required depends on the situation.

So, what are the conditions of cracks that indicate that the tire needs to be replaced?

First, the tread loss is close to the wear mark.

Any brand of tire has a wear mark at the bottom of the tread groove, also known as a "warning line". Generally, the height of the wear mark on passenger car tires is millimeters (the minimum groove depth of legal tires), and the height of wear marks on truck tires is millimeters.

2. Tire cracks or bulges and other damage.

In daily driving, the owner will inadvertently run over the small iron pieces, glass ballast, iron nails and other metal foreign objects on the road, and the car will inevitably encounter tires that are punctured. Tire damage includes tread cracks, tread bulges, missing tread rubber, severe sidewall wear, and tires that have been punctured by foreign objects many times. Especially with bulging tires, there is a danger of bursting tires at any time.

As long as the tires are found to be damaged, the owner should go to a professional tire shop as soon as possible to check the tires of his car and replace them in time.

3. The length of the tire age.

The service life of tires is usually about 5 years, and if they exceed the age, they will begin to age, the main manifestation is surface hardening, and then cracks appear, losing their due elasticity, and if they continue to be used, they will lead to tread deformation and the risk of puncture. It is recommended to replace the tires in time in this case.

If there is a small crack on the side of the tire, it means that the tire has been seriously aged and is not suitable for reuse, and should be replaced in time, as there will be a risk of puncture if you continue to use it. Tires are rubber products, and when exposed to wind and rain for a long time, they will gradually lose their original elasticity and toughness, so fine cracks will gradually appear. If the cracks on the tire wall are relatively small, they can be used on urban roads and do not need to be replaced for the time being, but they cannot run at high speeds.

The normal life of the tire is about five years, and there will be small cracks after about three years of use, if the cracks are not large, it is a normal aging crack or wear, which can not be replaced, but it needs to be checked regularly; If the crack appears on the sidewall, it is necessary to check it in time and replace it if necessary, because the sidewall is the most vulnerable part of the tire, and a puncture may occur if you continue driving.

The tires must be replaced in time in the following situations: 1. The sign that the tires are worn to the wear limit. It had to be changed (the tread depth was less than millimeters).

2. Tires should be replaced when they are aging (meaning that there are countless small cracks on this pattern) 3. Tires with deformed tread or bead damage, driving without air will cause the sidewall to be crushed and damaged tires, and tires corroded by chemicals cannot be used. 4. Bulging tires cannot be used.

Under normal circumstances, if there is a crack and you need to change it, you can replace it with one, and then go to the four-s store to have a look. It will tell you that if it is not a bad thing, it's okay, if it's very serious, the flat pressure tire pressure is unstable, and you still need to change it in this case. Look at it, the specific situation is analyzed on a case-by-case basis, and there are few of these things.

It's best to find a professional to take a look.

After all, the security of this relationship is not waiting for sloppiness.

Normally, it must need to be replaced, if the location of the crack is on the tread, and it is okay to make do with it without running at high speed.

Hello, after reading your problem, generally the tire has cracks, it is dangerous, it is recommended to replace it in time.

It depends on what kind of cracks, how many cracks, the depth and location, ......

No.

There are small cracks on the surface of the tires of the car that do not need to be replaced. The normal life of the tire is about five years, but the tire will appear on the surface of the tire for about three years, if the crack appears on the tread of the tire, this is the normal aging wear of the tire rock Sakura, can be round and do not need to replace the coarse cavity cluster immediately, regularly check the tire on it. If the crack of the tire appears on the side of the tire, it is necessary to consider replacing the tire, because the side of the tire is relatively fragile, and if you continue to use it, it may burst the tire, affecting the safety of the owner.

The tires have cracks and need to be replaced. Generally when we love the tires of the car after 2-3 years, the side of the tire with the surface will gradually appear some small cracks, if we find that there are a large number of small cracks on the side of the tire, it is necessary to replace the tire, generally speaking, the life of tire wear is 3-50,000 kilometers, if even if the tire has not reached the wear limit and mileage, but the service life of the tire reaches 5 years or the side produces a large number of cracks, it is necessary to replace the tire.

Tire precautions1. Try to park in a cooler place during daily parking to prevent tires from being exposed.

2. Try to park the vehicle on a clean and pollution-free ground, and clean the tires regularly to avoid pollutants corroding the tires.

3. Beauty products such as tire glaze or tire wax can be appropriately used to delay the aging rate of tires.

If there are small cracks in the tires, they do not need to be replaced, but they need to be checked regularly, and if the cracks appear on the sidewall, they need to be checked in time and replaced if necessary, because the sidewall is a place where the tire is more fragile, and there may be a puncture if you continue to drive.

If the tire has a small crack, it does not need to be replaced, but it needs to be checked regularly, if the crack is relatively large, it needs to be replaced, and if the crack appears on the sidewall, you need to go to the store in time to check it, and replace it if necessary, because the sidewall is the more fragile place of the tire, and there may be a puncture if you continue to drive. Tires must be replaced in time if they have the following conditions:

1. A sign that the tire has worn to the limit of wear;

2. Tire aging;

3. Tires with deformed tread or bead damage;

4. Bulging tires. Automobile tire is one of the important parts of the car, it is in direct contact with the road surface, and the car suspension together to alleviate the impact of the car when driving, to ensure that the car has a good ride comfort and driving smoothness, and to ensure that the wheels and the road surface have good adhesion, so as to improve the traction, braking and passing of the car.

Generally, the normal life of tires is five years, and there will be small cracks after about three years of use, if the cracks are not large and appear on the tire tread, it is a normal aging crack or wear, which can not be replaced, but it also needs to be checked regularly; If the crack appears on the sidewall, it is necessary to check it in time and replace it if necessary, because the sidewall is the most vulnerable part of the tire, and a puncture may occur if you continue driving. If the crack is too long and too deep, it has reached the standard depth of the tire pattern, which is millimeters, and it also needs to be replaced.

Tires with cracks are recommended to be replaced. Tire aging can usually observe the tire tread and the lines on the sidewall, if cracks are common, then the ridge guess indicates that the tire has been seriously aged. At this time, it is recommended to replace the tire in time, the tire is a rubber product, when the rubber is exposed to the wind and rain for a long time, it will gradually lose its original elasticity and toughness, so it will gradually appear fine cracks.

Matters for the use of tire cracksGenerally, the normal life of tires is five years, and there will be small cracks after about three years of use, if the cracks are not big and appear on the tire tread, it is a normal aging crack or wear, which can not be replaced but also needs to be checked regularly, if the crack appears on the sidewall, it needs to be checked in time to the store, and replaced if necessary.

Because the sidewall is the most vulnerable place for tire shortage, there may be a puncture if you continue to drive, if the crack is too long and too deep has reached the standard depth of the tire pattern, that is, millimeters also need to be replaced, the tire tire is worn to the wear limit The sign must be replaced, and the tire must be replaced when it is aging.
