Method for checking the production date of automobile tires: 1. There is a set of numbers on the sidewall outside the tire, and the information of production date can be known from the last four digits of the sign, which consists of four digits "AABB". The first two "AA" indicate the week of the year, and the last two "BB" indicate the year. Matters needing attention in tire selection: 1. Check the production date: Choosing tires depends on the production date, just like choosing many daily necessities. Because of the long life of rubber tires, too long and too light storage time will affect the performance of tires, and tire puncture accidents may be life-threatening. 2. Check the anti-counterfeiting label: In order not to be deceived by merchants, check the anti-counterfeiting label in addition to the production date when selecting tires. Genuine new tires will have anti-counterfeiting marks, which are usually attached to the tire trademark. 3. observe the pattern: the pattern shape of the tire is very particular. Generally, the tires of family cars are mixed pattern tires, which can meet the needs of most weather.
