How to Check Tire Manufacturing Date?
2 Answers
You can identify it through the markings on the tire sidewall, usually in the format DOTXXXXX3115. The last four digits after DOT represent the tire's manufacturing date. The first two digits indicate the week of the year, and the last two digits indicate the year. 1. Tire Function: Car tires are one of the essential components of a vehicle, directly in contact with the road surface. Together with the car suspension, they help absorb shocks during driving, ensuring good ride comfort and smooth driving performance. They also ensure excellent adhesion between the wheels and the road surface, improving the vehicle's traction, braking, and off-road capability. 2. Tire Structure: Divided into radial tires and bias-ply tires. Tread patterns can be categorized into ribbed patterns, transverse patterns, mixed patterns, and off-road patterns.
I've been driving for many years and always check the date when changing tires. Look at the sidewall of the tire for the DOT serial code—the last four digits indicate the production date: the first two digits represent the week, and the last two represent the year. For example, 1324 means the tire was produced in the 13th week of 2024. Even if tires show no wear, they can still age over time. Typically, after 5 years, the rubber hardens and becomes prone to cracking or blowouts on the road. Regularly checking the date helps ensure driving safety. I make it a habit to inspect my tires every six months to avoid being tricked into unnecessary replacements. Tire lifespan also depends on the environment—tires exposed to constant sunlight age faster. Regular maintenance is key; don’t skimp on small expenses that could lead to big problems.
