What does yyy on tires mean?
2 Answers
Tire yyy represents the prefix for the production date, with the following numbers indicating the specific date. Below is a detailed introduction about tires: 1. Composition: Tires are one of the most important components of a vehicle. Their main functions include supporting the entire weight of the vehicle, bearing the load of the car; transmitting traction and braking torque, ensuring the adhesion between the wheels and the road surface, and mitigating and absorbing vibrations and impacts during driving. 2. Function: Preventing automotive components from severe vibrations and early damage, adapting to the high-speed performance of the vehicle and reducing noise during driving, ensuring driving safety, handling stability, comfort, and energy efficiency.
The 'yyy' on the side of a tire usually refers to the year code. The last two digits represent the production year, for example, '23' means it was produced in 2023. This marking is particularly important because tire rubber naturally ages. If you see that a tire is over 6 years old, even if the tread is still deep, I would recommend replacing it. After all, safety comes first. Last time when I helped my neighbor check his car, I found that his 2017 tires had cracks on the side. When choosing tires, pay attention to the date to avoid buying stock tires. The production week number is in the first two digits, for example, '3523' means the tire was produced in the 35th week of 2023.
