How many years can a car tire be used before replacement?

Car tires can be replaced after 3 to 5 years of use. They are circular elastic rubber products assembled on various vehicles or machinery for ground rolling, usually mounted on metal rims. The following are the functions of tires: 1. Bear the weight of the car; 2. Ensure good adhesion between the wheels and the road surface; 3. Improve the car's traction, braking, and passing ability; 4. Directly contact the road surface and work with the car suspension to mitigate the impact during driving, ensuring good ride comfort and smooth driving. Extended content: The maintenance methods for tires are: frequently remove debris from the tire tread; check the wear of the tires and replace them in time; regularly check the tire pressure; repair the tire in time.
Having driven for over a decade, I've found that the timing for tire replacement truly varies from person to person. Generally, you should consider replacing them after 5 to 7 years, but it's not just about the age—mileage is crucial too. For example, with an average family car driven about 10,000 kilometers annually, tires typically need replacement after 50,000 to 70,000 kilometers due to wear. I remember my last tire change was when my car hit 6 years and 60,000 kilometers; the tread depth was already nearing the warning line of 1.6 mm. Safety comes first—aged tires are prone to blowouts on highways, posing too high a risk. So, I advise everyone not to focus solely on the years; check your tires every six months for cracks or bulges, and get regular balancing and rotation at a repair shop. Tires are like shoes for your car—when they're worn out, replace them. Don't skimp on this small expense.
I believe the timing for tire replacement is primarily for safety reasons. After years of driving, I've always followed one principle: regardless of mileage, tires must be replaced after 6 years. Tire aging is a gradual process, and exposure to sunlight and high temperatures can accelerate deterioration, making the rubber brittle and reducing grip. I remember once, a friend didn't replace his tires for 8 years and nearly lost control during a high-speed turn in the rain. Checking wear is crucial—you can use the coin test: insert a coin into the tread, and if the entire pattern is visible, it's time to replace them. Of course, mileage matters too. If you don't drive much, just cruising around the city, you might stretch it another year or two, but don't exceed 10 years. I recommend a simple check of tire pressure and appearance every quarter—safety is no small matter.
