How to Check the Production Year of Tires?
2 Answers
Observe the DOT marking. Here are the specific details: Observe the DOT marking: The last four digits of the marking indicate the production date, consisting of four digits AABB. The first two digits AA represent the week of the year, and the last two digits BB represent the year. Introduction to bias-ply tires: From a design perspective, bias-ply tires have many limitations, such as accelerated tread wear due to friction between the cross plies, and the ply arrangement does not provide good control. Introduction to radial tires: Radial tires have steel belts with better flexibility, adapting to irregular road impacts and offering long-lasting durability. Their fabric structure results in a longer tire lifespan.
Regarding tire age, I've been driving for over 20 years and often help friends check theirs. Look for the DOT code on the tire sidewall - the last four digits are crucial. For example, '3119' means the tire was manufactured in the 31st week of 2019. Tires typically last 3-6 years and should be replaced after that because aged rubber cracks, reducing wet traction and compromising braking safety. Parking away from direct sunlight can extend their lifespan. Remember to regularly check tire wear - replace them when tread depth falls below 1.6mm. Safety comes first; don't risk major consequences for minor savings.
