Theoretically, it depends on "T" - Treadwear wear resistance index (the wear value is generally between 160-540). The value represents the mileage that the tire can travel in the same use environment. The value The larger the tire is, the more wear-resistant the tire is.

Tips: Not all tires have a "3T index"; and because the "3T index" does not fall within the mandatory scope of the national standard, but is a value calibrated by each tire factory according to their own testing standards, it may appear The situation is: one brand of Treadwear is 400, and another brand is 340, but the 400 Treadwear is not necessarily more wear-resistant than the 340.

The wear resistance of tires is related to the formula and hardness of the rubber to a certain extent.

Extended information:

Tire manufacturers generally recommend a service life of 3 to 5 years, with a mileage of no more than 60,000 kilometers under comprehensive road conditions.

There will be four digits on the sidewall of the tire to indicate the date of manufacture of the tire. The first two digits represent the week and the last two digits represent the year. For example, 4117 means production in the 41st week of 2017.

But if the wear is serious, even if it is only used for a year, it still needs to be replaced; and if the tire wear is not obvious, it is recommended to replace the tires that have been in service for more than 5 years, because the tire rubber is easy to harden and age over time. , become brittle, have cracks, become harder in the cold winter, or expand in the hot summer, all of which may lead to the risk of a tire blowout.

Tires should be cross-transposed after 1w kilometers of use to make them wear evenly and increase the service life of the tires. Single-guide patterns cannot be transposed cross-wise, only front-to-back transposition.
