After how many kilometers should car tires be replaced?

[Tami]

Car tires should be replaced after driving 60,000 to 80,000 kilometers. Tires are usually made of wear-resistant rubber materials and can be divided into solid tires and pneumatic tires. Pneumatic tires consist of inner tubes and outer tires. The replacement of car tires also requires attention to the tire's own wear, damage, and degree of aging. Tire wear indicators: Each tire tread groove has wear indicators. Generally, the wear indicator thickness for household cars is 1.6mm. If the tire pattern is level with the wear indicator, it means the tire needs to be replaced. Tire cracking or bulging: After being scratched, car tires are prone to sidewall damage, bulging, or cracking. Tire bulging is caused by the breakage of the cord fabric inside the sidewall. Damaged tires need to be replaced in time, otherwise, blowouts are likely to occur. Tire aging: Generally, the service life of tires is 5-6 years. You can check the tire's production date to determine this. Over time, even with careful driving, surface hardening and cracking may occur.
