What is the service life of Michelin tires?
3 Answers
Generally, the service life of Michelin tires is about 3 years or approximately 50,000 kilometers. The lifespan or mileage of Michelin tires is influenced by many factors as follows: 1. Working air pressure: Both under-inflation and over-inflation will affect the tire's service life. If the tire pressure is too low, its radial deformation will increase, causing excessive deformation on both sidewalls, which leads to shoulder wear on the tread crown. This raises the tire temperature and significantly shortens the tire's lifespan. 2. Climate environment: The local climate conditions in different regions can affect the rubber aging speed of tires. Aged tires lose their proper elasticity, and continued use may cause tread deformation, increasing the risk of blowouts and reducing braking effectiveness. 3. Tire temperature: During driving, tires experience tension, compression, and friction, which raises their temperature. Excessive temperature can accelerate tire wear and even cause blowouts. 4. Driving habits: This is a factor directly related to the car owner. Aggressive acceleration, sudden turns, emergency braking, high-speed driving on rough roads, frequently mounting curbs, and scraping obstacles when parking can all cause severe tire wear, thereby shortening the tire's lifespan.
I just replaced my third set of Michelin tires, each lasting about 5 years or running 60,000-80,000 kilometers. Once, the tread was almost worn out, and I only remembered to change them after experiencing slippage on the highway during rain. Actually, it mainly depends on driving habits. Like me, stuck in city traffic every day, my tires last two years longer than my colleagues who frequently drive long distances. There's a small triangular mark on the side of the tire; when it's worn down to that point, it's time to replace them. Additionally, rubber ages. Last time I found a spare tire in the garage, it had cracked. So don't just look at the mileage; if they're old, they need to be replaced too. Regularly checking tire pressure and wear is crucial since it affects braking distance and safety.
Our auto repair shop has seen various cases of Michelin tires being scrapped. The normal service life is around 5 years, but many factors affect longevity. Driving frequently on concrete roads causes faster wear, gravel roads increase puncture risks, and highway driving wears tires more than city use. The key is ensuring tread depth doesn't fall below 1.6mm. Last time, a customer insisted on driving with cracks in the tread pattern, resulting in a dangerous highway blowout. Weather significantly impacts too - winter makes rubber harder and more prone to cracking. We recommend wheel alignment every 20,000 km to extend service life. For frequent harsh road conditions, inspection and replacement should occur around 4 years.
