How often should tires be replaced on a new car?
2 Answers
For new car tires, manufacturers generally recommend replacement every 3 to 5 years for safety reasons. Tires are circular elastic rubber products mounted on various vehicles or machinery that roll on the ground. They are often used under complex and demanding conditions, enduring various deformations, loads, forces, and high/low temperature effects during driving. Therefore, they must possess high load-bearing capacity, traction performance, and cushioning properties. Any brand of tire will have wear indicators at the bottom of the tread grooves. For ordinary car tires, the wear indicator height is 1.6 millimeters, which is also the legally mandated minimum tread groove depth. For truck tires, the wear indicator height is 2.4 millimeters.
I've been driving for over ten years, and I remember that new car tires don't need to be replaced immediately after purchase—they usually last several years. My own car's original tires lasted nearly 50,000 kilometers in the first three years before replacement, mainly depending on tread depth and wear condition. If you frequently drive on highways or brake aggressively, they may wear out faster. I recommend checking them every six months or quarterly by inserting a coin into the tread—if the entire head of the coin is visible, it means the tread is too shallow and it's time to replace them. Additionally, aging cracks are another sign; tires can also crack if left unused for too long. Never wait until they're completely worn out to replace them—that's quite risky, as damaged tires are prone to blowouts, especially on wet roads during rain. Regularly monitor tire pressure and keep it within the manufacturer's recommended range to extend their lifespan. Generally, new car tires should be replaced every 30,000 to 50,000 kilometers or every 3 to 6 years, but it ultimately depends on your driving habits and road conditions. A simple rule is to inspect them often.
