How is the tire cycle calculated?
3 Answers
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.
As an average car owner, I consider tire lifespan to be about how long tires can last, and I usually calculate it based on mileage. My car is mostly driven in the city, and typically, tires last around 40,000 to 60,000 kilometers—I keep a rough note on the odometer. Additionally, it's important to regularly check tread depth. You can buy a simple depth gauge or use a one-yuan coin for testing—insert the coin's head into the tread; if the entire national emblem is visible, it's time to replace them. Don't overlook time either—rubber starts aging after five years, becoming prone to cracks and blowouts, so I take my car to the maintenance shop every six months for a check-up. Driving habits matter too—hard braking or overloading can accelerate wear, and hot summer roads can damage tires. In short, safety comes first—don't wait until there's a problem to replace them. Spending a little money for peace of mind is worth it.
I've been in the auto repair business for several years, and the algorithm for tire lifespan essentially comes down to wear level and usage time. The simplest method is to check the wear indicators – those raised little lines in the middle of each tire. If a depth gauge shows they're below standard, it's time for replacement. In terms of mileage, city driving typically allows about 50,000 km, while highway-heavy driving requires caution after just 30,000 km. Regular tire rotation helps even out wear, potentially extending life by 10,000-20,000 km. Maintain proper tire pressure – too low wears the outer edges, too high damages the center – with monthly checks being ideal. Don't forget rubber aging: tires older than five years become dangerous regardless of mileage. Educate customers regularly to prevent blowouts. While maintenance costs are low, proper care brings both peace of mind and savings.
