How to Check Tire Age?
3 Answers
To check the tire age, follow these steps: Look for a series of numbers on the outer sidewall of the tire. The last four digits represent the production date of the tire in the format AABB, where the first two digits indicate the week of the year, and the last two digits indicate the year. The functions of tires are as follows: 1. Support the entire weight of the vehicle and bear the load of the car. 2. Transmit traction and braking torque, ensuring good adhesion between the wheels and the road surface to improve the car's power performance, braking performance, and off-road capability. 3. Protect automotive components from severe vibrations and premature damage.
I've been driving for over 20 years and have checked tire dates countless times. There's a DOT code on the tire, usually on the sidewall, where the last four digits indicate the manufacturing date. For example, DOTXXXX2222 means the tire was made in the 22nd week of 2022. Tire age is crucial because rubber deteriorates over time, and tires should generally be replaced every 5 to 6 years. I've seen a friend experience a blowout on the highway due to expired tires, so I always take a photo to record the date whenever I get new tires. Additionally, checking tire pressure and tread wear is essential, as aged tires are prone to tread cracking, which can compromise handling and safety. I recommend that beginners take half a minute after parking to check the DOT code—making it a habit can prevent major issues. When replacing tires, choosing ones with a more recent manufacturing date offers greater peace of mind.
I usually drive a small car to and from work, and I often check the details of my tires. Checking the tire date is actually quite simple. The tire sidewall has a DOT mark, and the last four digits tell you the production week and year. For example, 0923 means the 9th week of 2023. Tires older than 6 years can be dangerous as the rubber hardens and becomes brittle, affecting braking distance. I regularly check tire pressure and look for surface cracks, and I try to avoid parking in direct sunlight for too long to prevent accelerated aging. During maintenance, I also ask the mechanic for their opinion. As a daily driver, checking tire dates is like checking my health—a little time spent can ensure greater safety and save on future repair costs.
