The production date of automobile tires is very easy to identify. In a small square on the sidewall of the tire, the date of production of the tire is marked, which consists of four digits, with the last two digits indicating the year and the first two digits indicating the week.

Extended data:

The direction of rolling

Rolling direction: The tread pattern on the tire is particularly critical for drainage and anti-skid during driving. Therefore, the rolling direction of off-road vehicle tires with asymmetric tread patterns is often marked with arrows to ensure the adhesion and anti-skid performance of the design. If it is not installed correctly, it will be counterproductive.

Wear limit sign

Wear limit sign: The wear limit of the tire is marked on one side of the tire with a rubber strip and a block. Once the tire wear reaches this mark position, it should be replaced in time, otherwise it will burst because of insufficient strength.

batch number

Production batch number: a set of numbers and letters are used to indicate the year and quantity of tire manufacture. For example, "98N08B5820" means the 5820th tire produced by Group 65438+B in August 1998. The production batch number is used to identify the newness and storage time of tires.
