How many kilometers can a normally driven car tire travel?

[StJuliette]

For mainstream brand tires under normal wear conditions (primarily driven on urban roads without habits of sudden braking or drifting), they can generally travel around 100,000 kilometers. Methods to determine tire lifespan: Tire lifespan is related to many factors such as vehicle type, load capacity, driving habits, and road conditions. Therefore, tires have wear indicators to judge their lifespan, which is a relatively economical and appropriate method. Car tires have wear limit markers. Once the wear reaches or exceeds this marker, the tire has reached its lifespan. Traction and friction will significantly decrease, affecting car braking and cornering. In such cases, the tire must be replaced. When to replace tires: When the tire surface is close to the wear marker, it indicates that the tire wear has reached a level that affects normal performance. At this point, consider replacing the tire. If the tire tread is already level with the wear marker, the tire must be replaced immediately. Another situation is when the tire has a bulge. The structural integrity of a tire comes from the internal layers of nylon and steel wire mesh. When a tire suffers external impact, part of these layers can be damaged, causing the rubber to lose its structural support and form a bulge under high pressure. Such tires should be replaced as soon as possible, though they can be kept as spare tires.
