What is the tire wear resistance index?
1 Answers
Tire wear resistance index refers to the wear resistance performance of a tire, which is the tire wear life grade, usually represented by a number. The TREADWEAR + number marked on the side of the tire is the tire wear resistance index. The wear resistance coefficient is TREADWEAR + number, for example, TREADWEAR280 means the tire's wear resistance is 280% of the standard tire. It should also be noted that the higher the tire wear resistance index, the better, because its improvement often comes at the expense of other performance factors, such as handling and comfort. Except for vehicles used for commercial purposes, a wear resistance index of around 200-350 is generally considered optimal. The wear resistance of a tire should not be judged solely based on its wear resistance index; it should also be determined in combination with driving conditions and habits. When the tire wears down to the wear indicator, it should be replaced in a timely manner. Generally, the service life of a tire is about 5 years, and the production date is also marked on the side of the tire. If the tire shows no obvious wear but has been in use for more than 5 years, it is also recommended to replace it, as tires are rubber products that can age over time, develop cracks, and increase the risk of a blowout, endangering driving safety.
