How Often Should Passenger Car Tires Be Replaced?
2 Answers
Tires should generally be replaced every 5 years or after 60,000-80,000 kilometers, depending on local road conditions and specific usage. Relevant information about tire replacement is as follows: 1. The service life of tires is 5 years or 60,000-80,000 kilometers. Beyond this period, tires begin to age. The main signs of tire aging are surface hardening and the appearance of cracks. Aged tires lose their elasticity, and continued use can lead to tread deformation, increasing the risk of a blowout. 2. All tire brands have a wear indicator at the bottom of the tread grooves. For passenger car tires, the wear indicator height is 1.6mm, while for heavy-duty tires, it is 2.4mm. If tires are not replaced in time, the tread pattern cannot effectively channel water away on wet roads, significantly increasing the risk of losing control of the vehicle.
I've been driving for over ten years, and changing tires depends on the specific situation. Generally, it's recommended to replace car tires every 5 to 6 years because rubber deteriorates over time—even if they look new, reduced elasticity can compromise safety. In terms of mileage, standard tires can last 60,000 to 80,000 kilometers, but frequent braking in congested urban areas accelerates wear. I make it a habit to check tire pressure every three months to ensure it’s neither too high nor too low, and I also inspect the tread wear indicators—if they’re worn down, replace the tires immediately. Don’t cut corners to extend tire life; old tires are prone to skidding or blowouts, especially in rainy conditions or at high speeds. When installing new tires, I recommend getting a wheel alignment for smoother driving and better fuel efficiency. Remember, regular maintenance helps detect issues early—don’t wait until an accident happens to regret it.
