What is the maximum service life of car tires?
2 Answers
The maximum service life of car tires is 6-8 years. Methods to extend tire life are as follows: 1. Develop the habit of regularly checking tire pressure: Tire pressure is the key to extending tire life. If the tire pressure frequently exceeds the normal pressure by 20%, the tire's lifespan will decrease by 10%; if it is frequently 30% below normal pressure, the tire life will be reduced by 52%. 2. Maintain consistent tire pressure: Tire pressure is the lifeblood of tires. If the pressure is too low, the tire body deformation increases, cracks are prone to appear on the tire side, and excessive heat generation occurs, accelerating rubber aging, fatigue of the cord fabric layer, and cord breakage. 3. Develop the habit of regularly removing foreign objects from tires: When driving on the road, small stones often get squeezed into the tread grooves of tires. If these small stones are not removed in time, they can puncture the tire over time, leading to air leakage or blowouts.
Having driven for over a decade, I've deeply realized that tire aging is a gradual process. At first, the effects aren't noticeable, but after five years, you can clearly feel reduced grip and longer braking distances. While many people focus only on tread wear, they often overlook the tire's age. Professional advice suggests tires should be replaced within ten years at most, even if they appear fine. This is because rubber hardens and cracks with age, and aging accelerates in hotter climates. I remember once on the highway, I discovered tiny cracks on the sidewalls of tires that were over seven years old, prompting an urgent replacement for peace of mind. During routine maintenance, always check the tire's production date—the four-digit code, like 2323, which means the 23rd week of 2023. Safety first—don't wait until a blowout to regret it.
