How Often Should Family Car Tires Be Replaced?
2 Answers
Family car tires should be replaced within five years. Here are the relevant details: Conditions for replacing family car tires: Tires must be discontinued when worn to the wear limit indicator (i.e., when the tread depth is below 1.6 mm). Tires with deformed treads or damaged bead areas, those that have been run underinflated resulting in sidewall damage, or those corroded by chemicals should not be used further. Shelf life of family car tires: The sidewall of the tire will have a four-digit number indicating the manufacturing date, with the first two digits representing the week and the last two the year. Generally, tires should not be used for more than 3 years or exceed 60,000 kilometers in mileage. While slightly exceeding these limits may not cause immediate issues, the low temperatures in winter and rainy conditions in summer can significantly reduce the tire's wet grip and dry handling performance.
After years of driving, I believe replacing tires for family sedans depends on two factors: wear and aging. If the tread depth is too shallow, it's time for a change. Insert a one-yuan coin into the tread—if the serrated edge at the top is fully exposed and measures less than 1.6mm, replacement is due. Generally, check every 50,000 to 80,000 kilometers; city driving may allow longer use, while frequent highway trips accelerate wear. Rubber aging is a silent killer—parking outdoors with prolonged sun exposure leads to visible cracks after four years, increasing blowout risks. Safety first: conduct simple self-checks every six months. Hot weather softens rubber and speeds up aging, so remember to park in shaded areas to prolong tire life.
