What is the normal service life of tires?
1 Answers
There is currently no official authoritative statement on how long tires last. It is generally believed that the service life of tires is 3 to 5 years, and they should be replaced based on wear conditions within this period. Here are the methods to determine when to replace tires: 1. Tread wear approaching the wear indicator: Any brand of tire will have a wear indicator at the bottom of the tread grooves. The wear indicator height for passenger car tires is generally 1.6 millimeters (this is also the legally mandated minimum groove depth), while for load-bearing tires, the wear indicator height is 2.4 millimeters. 2. Tire damage such as cracks or bulges: Damage to tires includes tread cracks, tread bulges, missing tread rubber, severe sidewall wear, and repeated punctures by foreign objects. Especially with bulges, there is a risk of tire blowout at any time. If any of these damages are found, it is advisable to take the vehicle to a professional tire shop for inspection and timely replacement. 3. Tire age expiration: The service life of tires is typically around 3 to 5 years. Beyond this period, tires begin to age. The main signs of 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.
