How Many Years Should Car Tires Be Replaced?

[ElizaLee]

For household car tires, it is generally recommended to replace them every 4 years or around 80,000 kilometers, whichever comes first. Even if you only drive 1,000 kilometers a year, the tires must be replaced after 4 years because the service life of car tires is approximately 4 years. Situations where car tires need replacement: 1. Tire wear: Manufacturers set a usable range for tires during production. By carefully inspecting the tire tread, you can find a small protrusion in the tire grooves—this is the tire wear indicator. When the tire tread wears down to this mark, the tires should be replaced. 2. Tire cracking or bulging: During vehicle use, tires may develop cracks. Minor cracks can be repaired and used further. However, if the cracking is due to aging, the rubber loses its flexibility and becomes brittle, increasing the risk of a blowout under heavy loads. The same applies to tire bulges. 3. Prolonged vehicle usage: Some car owners drive infrequently, possibly covering less than 10,000 kilometers a year, resulting in minimal tire wear. However, even with such usage, attention is needed. Rubber has a limited lifespan; once it reaches its age limit, it begins to harden, crack, and eventually deform.
