How is the tire cycle calculated?

[LeViolet]

The tire cycle is usually marked on the outside of the tire. There are numbers engraved on the tire sidewall. The last four digits of this mark indicate the production date. For example, if the last four digits are 0813, it means the tire was produced in the eighth week of 2013. Based on the date conversion, the tire was produced at the end of February. Below is relevant information about tires: 1. Function: The tire is one of the important components of a car. It directly contacts the ground and, together with the car's suspension system, mitigates the impact experienced during driving. A good tire ensures excellent adhesion between the wheel and the road surface, thereby improving the car's traction and driving performance. 2. Different cars have different tires: The car's tires need to bear the weight of the car when it is unloaded and fully loaded, so vehicles of different weights have different tires. Some models are also equipped with spare tires, which are divided into full-size spare tires and non-full-size spare tires. Full-size spare tires are the same as the original tires, while non-full-size spare tires can only be used as temporary replacements.
