How many kilometers should a car tire be replaced? When should a car tire be replaced?

Because car tires have deep treads, they can grip the ground well, increase friction with the ground, and avoid driving accidents. After long-term driving, the surface of car tires will inevitably wear out, so car tires need to be replaced regularly. Let's take a look at the conditions for replacing tires.

How many kilometers should car tires be replaced?

Generally speaking, car tires need to be replaced after driving about 60,000 to 80,000 kilometers. If the car tires are used for more than 3 years, they should also be replaced because the aging process of the tire rubber will be accelerated.

If the tire is not used, after three years of protection, the rubber will inevitably harden, not to mention that the tires of vehicles in motion are often exposed to the sun and rain. If cracks appear on the surface of the tire, it is even more necessary to replace it.

However, it is not ruled out that some cars have been driven for a long time and a long distance, and the tread is still very clear. Therefore, it is necessary to check the tire tread and aging degree. After all, driving habits and road conditions are the direct factors affecting tire wear.

What is the condition of the car tire? Should it be changed?

1. Pattern depth

The wear limit of the tire is 1.6mm, and it must be replaced at this depth, but we recommend replacing it when it reaches 3mm. If you don't drive long distances or high speeds, this pattern can be used on the rear tire.

2. Air pressure

The daily filling pressure also has a great impact on the life of the tire. If the pressure is too low, the tire shoulder will wear out.

Excessive air pressure will wear the center of the tread, which will cause the tire to wear prematurely and reduce its lifespan.

3. Traumatic swelling

Trauma, especially on the sidewalls, can be a huge safety hazard, and because family cars don't have steel belts here, they must be replaced.

A bulge is caused by the breakage of the carcass cord after the sidewall is crushed. It poses a great safety hazard because the air pressure inside the tire is very high, which can easily cause a tire blowout.

4. Eccentric wear

Due to problems with the chassis four-wheel alignment data, the tires are worn unevenly. At this time, if the tire pattern is acceptable, you can replace the tires after adjusting the four-wheel alignment data, and you can still drive for a while.

How to reduce tire noise

1. The tire pressure should be moderate. Too high or too low will increase the tire noise.

2. The vehicle's tires are relatively hard, so the noise will also become louder. You can choose tires with better silent effects to improve the noise problem.

3. For sound insulation and noise reduction, you can consider sound insulation of the wheel cavity, which will have some effect. For example, spraying a layer of sound insulation glue or chassis armor can also reduce tire noise.
