Decoding Tire DOT Codes: How to Check the Age of Your Truck Tires

“A stitch in time saves nine,” as the old saying goes. Mr. Quang, the owner of a Dongfeng B180 truck used for transporting construction materials on the Cau Giay – Ha Dong route, shares: “Vehicles are like people, they need to be cared for from the smallest details. With tires, I always pay close attention to everything from the brand and size to the manufacturing date to ensure safety on every road.” Indeed, understanding the tire’s manufacturing date is crucial for ensuring safety and extending the lifespan of your “faithful companion.” So how do you “diagnose” a tire’s age just by looking at a few numbers? Let Xetaihanoi.edu.vn decode this mystery for you!

Tire DOT Code: Your Key to Safety

Spotting the Manufacturing Date: A Quick Guide

Identifying the manufacturing date on a tire is surprisingly simple. Just locate the characters within an oval or rectangular frame on the tire sidewall, usually consisting of 4 digits. The first two digits represent the week of production, while the last two digits indicate the year of manufacture. For example, the sequence “3221” indicates that the tire was manufactured in the 32nd week of 2021.

Do Tires Have an “Expiration Date”?

Like food, tires also have a limited lifespan, typically 5-6 years from the date of manufacture, or even shorter depending on usage and storage conditions. Using expired tires poses significant safety risks, especially when driving on slippery roads or braking suddenly.

Expert Advice: Mr. Nguyen Van Nam, a mechanical engineer at Thaco Truong Long truck dealership, advises: “To ensure safety, vehicle owners should replace tires after 5 years of use or when the tires show signs of aging such as cracks, dryness, or tread wear…”

• Buy tires from reputable dealers: Avoid buying low-quality or retreaded tires.
• Thoroughly inspect tires before purchasing: Pay attention to technical specifications, manufacturing date, and tire condition (cracks, dryness, tread wear…).
