How often should small car tires be replaced?

[HeidiLee]

Small car tires can be replaced after driving 80,000 kilometers. The replacement interval for car tires can be determined based on the wear condition of the tires and their shelf life. As the tire rubber gradually ages, deep cracks will appear on the sidewalls of the tires. However, as long as the sidewalls have not been impacted and the cords are not broken, the tires can continue to be used. To determine whether a car needs new tires, regularly check the tire wear indicator baseline. When the tread wear on the outer part of the tire reaches the replacement baseline, it indicates that the tire needs to be replaced. If not replaced in time, the car may sway left and right during rapid acceleration, resulting in unstable driving. In severe cases, the grip and steering capabilities may decrease, leading to slipping during acceleration and deviation in direction.
