The car has a warning! These five points must be remembered!

According to statistics, 46% of traffic accidents are caused by tire failure, of which a flat tire accounted for 70% of the total tire accidents.

It is extremely dangerous if the tire burst during the vehicle driving, and may also lead to a series of catastrophic accidents. To check the tires before the car, early detection of problems, timely replacement of new tires, to avoid the occurrence of failure.

Old drivers in the past experience, summed up five points to determine whether the tire needs to be replaced, Xiaopang today to share with you.

01

Judging by the depth of the tread pattern

The thickness of the tread pattern must be greater than 1.6 mm, if you often drive on the wet road with low friction, it is best to ensure that the tread pattern thickness is twice the above value.

Old drivers often use one dollar coins to roughly estimate the thickness of the tread pattern, inserted into the tread gully along the direction of the top of the national emblem, because the distance between the edge of the coin and the top of the national emblem is between 1 and 2 mm, so if you can see the entire national emblem sign at this time, it indicates that the tread pattern thickness is insufficient.

02

Judging by the tread pattern wear indicator line

The tread pattern wear indicator line is a flat rubber strip, which is embedded in the tread groove vertically and longitudinally with the tread. When the tire is very new or the wear level is very low, the tread pattern wear indicator is hardly detected.

If one to two indication lines are displayed on the tire, the thickness of the tread pattern has been reduced a lot, and you should be extra careful when driving on the wet road. If all the indicators on the tire are clearly visible, it means that you need to replace the tire as soon as possible.

03

Look for cracks on the sidewall of the tire

If there are cracks and cuts on the side wall of the tire, it indicates that there may be air leakage cracks on the tire in the future, and worse, even cause the tire to burst.

Therefore, when the sidewall crack of the tire looks more serious, it is necessary to go to the repair shop to replace the tire as soon as possible.

04

Keep an eye out for bumps and blistering on your tires

In some cases, the outer surface of the tire will not be strong enough, resulting in bumps and bubbles higher than the normal tire surface.

If the vehicle is not sent to the repair shop in time to detect the tire failure, the insufficient area of the tire surface is likely to cause a sudden burst, especially under high-speed driving, and even lead to serious injury to the driver and passenger.

05

Whether there is excessive vibration and jitter

(for older drivers)

A certain amount of jitter in the process of moving the vehicle is inevitable, especially in poor road conditions. When you have a certain amount of driving experience, you can judge what kind of jitter is within a reasonable range by feeling yourself, and what kind of jitter indicates that the vehicle has a fault.

There are many causes of vehicle jitter, which may be the axial deviation of the tire or the imbalance of the force, or the problem of the shock absorber. But jitter can also indicate something is wrong inside the tire; Even if the tire is not the root cause of the vehicle shake, shake can harm the performance of the tire. Therefore, if your car has more serious shaking, especially the shaking on the road in good condition, immediately drive the vehicle to the repair shop for inspection. Always bear in mind that a large degree of jitter is often a precursor to vehicle failure.

The cause of a flat tire

Tire aging:

The service life of tires is generally 3-5 years.

External shocks:

Deep pits on the road, hard ridges, nails and wire are hidden dangers of flat tires.

Oversteer:

Excessive steering at high speed directly causes a flat tire.

High or low tire pressure:

Too high tire pressure will burst, and too low tire pressure will cause damage to the tire wall and burst the tire.

Overload and overspeed:

Each tire will be marked with a load index and speed level, if the actual load and speed of the vehicle exceed the tire calibration range, there will be a risk of blowout.

Hot weather:

We call summer the tire burst season because, once the road temperature rises, the tire and the road friction causes the tire surface temperature to be very hot. Under thermal expansion and cold contraction, the tire body expands and thinens, which easily leads to a burst tire.

How can I prevent a flat tire

Regular replacement:

The service life of the tire is 3-5 years, and the general position of 20,000 kilometers is changed once to avoid tire partial wear;

Air pressure standard:

The tire pressure must be within the standard range, not too high or too low, and the tire pressure data of the whole car should be unified;

No more than three:

When the tire patch is more than three, the tire wall or the Angle between the tire wall and the tire surface is pierced, it is not recommended to repair the tire, and it needs to be replaced in time;

Regular purchase:

Fakes are rampant, refurbished as true, and only formal channels can be purchased to ensure safety.

Do this if you have a flat tire

1. Stay calm;

2. Control the steering wheel with both hands and try to keep the original driving direction;

3. Release the throttle immediately;

4. Do not brake sharply, otherwise it will easily cause rollover. You can continue to drive a short distance, tap the brake;

5, the speed is naturally slow, observe the rearview mirror;

6. Ensure safety and pull over;

7. Warning signs are placed 150 meters away.

The above is all about the blown tire, Xiaobang remind you, driving safety! Keep the above points in mind, if your tires have not been changed for a long time, go and check it.
