Michelin tires' lifespan depends on usage conditions, typically lasting two years or 60,000 kilometers, whichever comes first. Below are precautions for tire usage: Check tire pressure regularly: Car tire pressure should be maintained between 2.3-2.5 bar. Prolonged overinflation or underinflation may lead to tire blowouts. Avoid tire impacts: Pay attention to road conditions while driving, avoid frequent travel on uneven surfaces, and control speed when crossing speed bumps or curbs to minimize impact on tires. Inspect tire wear promptly: Examine tires for bulges, cracks, cuts, punctures, aging or abnormal wear. Check tread groove depth - if wear approaches the tread wear indicator, replace tires immediately.

Many of my friends use Michelin tires. From my observation, regular passenger car tires typically last 60,000-80,000 km. The key is to look at specific models - for example, the energy-saving Primacy series on my car lasted 70,000 km before replacement, while the Pilot Sport performance tires wore out after just 40,000 km. Pay attention to two things: check tire pressure monthly (maintain 2.3-2.5 bar) and rotate tires every 8,000 km. Last week at the repair shop, I saw a Camry with wave-shaped tread wear still being driven - this is particularly damaging to the suspension. When the small raised blocks in the tire grooves are nearly worn flat, it's time to replace them. Don't wait until they're completely bald - it's very dangerous for hydroplaning in rainy conditions.

Over the years of ride-hailing, I've changed over twenty Michelin tires and gained some experience. For economical tires with a treadwear index above 300, like the Energy series, they can last 80,000 kilometers on city roads without issues. However, if you frequently drive on highways, it's recommended to inspect them at 60,000 kilometers, as the friction and heat generated on highways can accelerate aging. Once, while driving passengers on a mountain road, a new tire burst after just 30,000 kilometers because the sidewall was damaged by a rock and not addressed in time. Remember to check the tire sidewalls for bulges or cracks every time you wash your car—this is more important than just looking at the mileage. Also, always get a wheel balance when changing tires, or the steering wheel might vibrate.

Friends who are into car modifications often complain that Michelin sport tires aren't durable, but their grip is indeed strong. Performance tires like the PS4S might wear out after just 30,000 kilometers under aggressive driving. At last year's track day, I saw a modified Civic drifting with its front tires worn down to the cords. For normal driving, it's recommended to replace them within 50,000 kilometers, with tire pressure about 0.2 bar higher than regular tires. Pay special attention to shoulder wear, which is a sign of frequent cornering. There's a saying in the modification scene: if you want performance, don't worry about mileage; if you want durability, go for XM2+.

A veteran auto repair shop master taught me that checking tire age is more accurate than mileage. Rubber begins to harden after five years, and tires should be replaced when spiderweb-like cracks appear on the sidewalls. I encountered an owner whose tires had only run 40,000 kilometers but were seven years old, and they blew out when hitting a pothole. You can check the production date on the Michelin official website—the four-digit number on the tire sidewall, such as '2923,' indicates the tire was produced in the 29th week of 2023. For those using winter tires in northern winters, pay special attention: clean them thoroughly and store them in a cool place when switching back in spring, or the rubber may crack the following year.

In the owner group chat about tire experiences, a pattern was noticed: EVs wear out tires faster than gas cars. My Model 3 originally came with Michelin PS EV tires, which needed replacement at just 40,000 km due to the motor's instant torque being tough on tires. Later, I switched to Primacy 4 quiet tires with a velvet-design tread, lasting 70,000 km in city driving. It's recommended to do a wheel alignment every quarter for EVs, especially monitoring rear tire wear for rear-wheel-drive models. Some owners added a tire pressure monitoring system, finding real-time tire temperature readings particularly useful. Remember to install new tires on the front and older ones on the rear for safety.
