How Often Should Family Car Tires Be Replaced?
2 Answers
Family car tires must be replaced every 60,000 kilometers or 4 years. Tires are circular elastic rubber products assembled on various vehicles or machinery for ground rolling. Rubber products will age after prolonged use. When purchasing new tires, be sure to check the production date clearly, as tires also have a shelf life. Tires are often used under complex and demanding conditions, enduring various deformations, loads, forces, and high-low temperature effects during driving. Therefore, they must have high load-bearing performance, traction performance, and cushioning performance, while also requiring high wear resistance, flex resistance, and low rolling resistance and heat generation.
My car has been running for five or six years, and last month during maintenance, the mechanic reminded me it's time to change the tires. There are two main points to consider: first, the tire tread depth is less than 1.6mm—I tested it by inserting a coin, and the tread is almost worn out; second, there are many small cracks on the tire sidewalls, and the rubber has clearly aged and hardened. I usually drive steadily for school runs and commuting, but the tires didn’t even last five and a half years. The mechanic said that tires older than five years, even if they look okay, will have much worse grip in rainy conditions. He advised not to push it, and after changing to new tires, driving over speed bumps feels much smoother.
