I bought my car last year, there is a little crack, I don t know if it can run at high speed at the

If the tire is broken, it is generally the side of the tire. The side of the tire is the thinnest part of the whole tire, but it is the part that crushes and changes the most during driving, and the load is very large, so no matter what tire you are, if there are scratches or damage on the side, whether it is a tire manufacturer or a car manufacturer, it is clearly stipulated that the side of the tire is injured, or the air leak cannot be repaired, and the tire must be replaced. The reason for this is that the side of the tire is the weakest according to the structure of the tire, with only a thin rubber layer and a plywood layer, which is a mesh layer woven with cotton thread and rayon.

If the sidewall of the tire is scratched, especially when the ply layer is damaged, the structural stress of the sidewall will be completely broken, and it is easy to cause a puncture accident. Therefore, when there is a broken skin on the side of the tire but there is no exposed line, we should also go to the maintenance agency as soon as possible to replace the tire, if the line is exposed, we must drive carefully, not drive too fast, and immediately go to the maintenance agency to replace the tire.

But look at your tire, not the side, theoretically it should be fine, use a small flat screwdriver to dig out if there are nails in it, glass slag and the like, if not, it doesn't matter.

Judging from the **, the wheels are still relatively new, and the total mileage will not exceed 10,000 kilometers. Estimated at 5, 6 thousand km, right?

Judging from the wound marks, it was scratched by a thin blade. This kind of scratch will not be a problem at all when driving in the city, and it is not a big problem to go on the highway for about 100 yards, but not more than 120 yards away.

There is also the air pressure should also be kept around, the highest should not be exceeded, and the above points can ensure that you drive safely on the high speed.

Your car was bought last year, so the tires are still relatively new, the surface crack of your tire does not affect high-speed driving, your crack does not occur on the side of the tire, if it occurs on the side of the tire, it is more dangerous.

If you find a crack in your car tires, I recommend that you go to a professional and regular car repair shop for consultation. If the situation is severe, continue to repair or replace the tire. Because it is more dangerous to run on the highway, we need to pay attention to a lot of details so that there will be no traffic accidents and we will be responsible for our own lives.

**See that your tire is caused by trauma, and the crack is not only on the tire pattern, but also on the smooth part of the tire side. For the sake of safety, it is recommended that you have better change the tire, otherwise the consequences of a puncture on the highway will be very serious.

It depends on how deep this crack is, and it won't have much impact if it doesn't hurt the body.

Can I still get on the highway with a repaired tire? Mechanic: Know these points and remember not to take risks!

The life of your tires is almost over, so it's time to replace it......The tires of June 15 years are generally changed for three years, regardless of whether you have mileage or not, for safety.

There are small cracks in the tire face of the car that need to be checked to determine if it can run at high speeds.

1. If the crack is very small and the depth is not more than millimeters, the impact is not great.

2. If the crack of the tire is obviously too large, you need to change to a new tire, otherwise it is very dangerous to run at high speed.

Maintenance of car tires:

1. Keep the distance between the cars at high speeds, avoid unnecessary or frequent braking (braking), reduce damage to the tires, and at the same time pay attention to the tread depth of the tires for their own safety.

2. There is a one-to-one correspondence between the load and the air pressure of the tire, and the load is too high is similar to the low air pressure, which will cause tire damage, and often used under overload, the service life of the tire will be reduced by 20%-50%; At the same time, the wrong loading method will also cause uneven tire load, affecting the excessive load of individual tires and reducing the life expectancy.

3. Air pressure is the life of the tire, and the air pressure of the tire must meet the air pressure specified by the national standard for different types and specifications of tires. It is necessary to check the air pressure of the tire frequently, as too high and insufficient air pressure will cause damage such as special-shaped wear, cracks at the bottom of the groove, broken cords, delamination of the cord layer, and tire bursting; If you want to continue to drive at high speed, the air pressure should be increased by 5%-10% above the standard air pressure; At the same time, the internal air will rise due to the increase in temperature after driving, and the tire cannot be deflated at this time.

4. It is necessary to change the tires on the vehicle in a timely and appropriate manner (insist on checking the tires during the first-level maintenance and second-level maintenance of the vehicle) to keep the tires evenly worn and prolong the service life; Tires with a slightly larger outer diameter should be mounted on the outer wheels.
