How often should new car tires be replaced?
2 Answers
You can determine whether new car tires need to be replaced based on the following criteria: 1. Car tires should be replaced every 3 to 5 years or 40,000 to 60,000 kilometers: After 2 to 3 years of use, small cracks will gradually appear on the sidewalls. If cracks are found, the tires should be replaced promptly. 2. If the tires have not reached the wear limit or mileage: Tires should also be replaced when they reach 5 years of use or when a large number of cracks appear on the sidewalls. As long as the tire sidewalls have not been impacted and the cords are not broken, they can continue to be used. 3. Tires need to be replaced when the actual wear limit is less than 1.6 mm: The triangular marks on the tire sidewalls can help the owner find a protrusion in the tread grooves to determine the actual wear limit of the tire. This value should be greater than 1.6 mm. If it is less than 1.6 mm, the tires need to be replaced.
This is a pretty common issue. I just helped my neighbor check his car. There's no fixed answer for how long new tires can last—it mainly depends on how often you drive. For regular family cars, tires usually need replacement after 50,000 to 80,000 kilometers. If you're driving long distances daily, they might wear out in just two years. Last week at the auto shop, I saw a car owner whose tires had only 30,000 kilometers over three years but were full of cracks on the sidewalls from constant outdoor parking. The key is to watch the small raised bars in the tread grooves—once they're worn down to the same level, it's dangerous. Every month, take a moment to crouch down and check for bulges or cuts, especially if you often drive on rough roads. Oh, and front tires wear faster, so remember to rotate them front-to-back every 20,000 kilometers to extend their lifespan.
