What is the lifespan of a typical tire?

Under normal driving conditions, the lifespan of a tire is generally 60,000-80,000 kilometers or 3-5 years. Of course, the service life of a tire is greatly influenced by driving habits, road conditions, parking environment, and other factors. The methods to determine the lifespan of a tire are as follows: 1. Check the degree of tire wear or whether the tire has aged: Almost every tire has wear indicators. Usually, a small triangular arrow mark can be found on the side of the tire, and following this mark will lead you to the wear indicators in the grooves of the tire tread. 2. The height of the wear indicators for general passenger car tires is 1.6 millimeters (this height is also the legally mandated minimum groove depth for tires), while the height for wear indicators on load-bearing tires is 2.4 millimeters. If the wear indicators are found to be level with the tread, it indicates that the tire is nearly worn out and should be replaced promptly. 3. Since tires are made of rubber, they naturally age over time, becoming prone to cracking, significantly losing heat dissipation capabilities, reducing driving comfort, slowing acceleration, and potentially losing control during braking due to insufficient grip, especially under high-speed driving conditions, which can be very dangerous. 4. If the aging of the tire has damaged the tire body, regardless of the mileage driven or the extent of wear, the tire needs to be replaced.
I've been driving for years, and tire maintenance is something you really can't be careless about. Generally speaking, most tires can last about 6 to 8 years or around 50,000 to 60,000 kilometers, but this depends on how often you drive and the road conditions. I commute on the highway every week, so they wear out faster; if you drive less, time becomes the more critical factor, as tires older than ten years are prone to cracking. It's best to get into the habit of checking tire pressure monthly and inflating to the manufacturer's recommended value—low pressure can cause uneven wear. Tread depth is crucial; when those little horizontal grooves wear down to 1.6 millimeters, it's dangerous. Also, don’t forget to rotate them regularly and get wheel alignments to avoid premature wear. Stay on top of safety, reduce the risk of blowouts, and drive with peace of mind.
I pay special attention to safety details, and tire aging should never be overlooked. The normal lifespan ranges from 5 to 10 years, but even with low mileage, the rubber can harden, affecting traction. I inspect tread wear every quarter by inserting a coin into the grooves—if the edge is visible, it's time for replacement. Worn tires can cause accidents at high speeds, so always note the production date by checking the DOT code. Storage conditions also matter significantly; keeping them in a garage extends their life, while prolonged sun exposure accelerates cracking. Avoid speeding or sudden braking to prevent excessive wear. Ensure timely replacements for stable braking performance.
