How to check the age of a tire?

You may know quite a bit about your tires, but do you know how old they are? Regardless of the brand name, materials, or construction style of a tire, they will not be safe to use forever. All tires have natural rubber in them. The rubber oxidizes and breaks down over time, just like other organic things do. Even if your tires still have a safe amount of tread, you may need to replace them if they get too old.

How to Find Tire Age

The sidewall of a tire tells you a lot about it-everything from its name to its size. To check the age of your tire, you need to find the DOT number. The Department of Transportation puts a DOT number on every tire manufactured for sale in the United States. It's next to the size information. The DOT number appears in a smaller type than the size code.

Check the sidewall for “DOT” followed by up to 13 letters and numbers. A tire’s sidewall is the smooth part of the tire outside the rim before the tread starts. Check both sides of the tire if you see an incomplete code on the outside—the full code is legally required to be printed onto one sidewall in the US, but there may only be a partial code printed on the other

Look for 4 numbers ending with 2 digits that look like a past year. The first 2 numbers tell you the week the tires were manufactured, and the last 2 tell you the year. If you see 2718, for example, that means the tire was made in the 27th week of 2018.

Look for 3 digits at the end of the DOT code if your tires are very old. Like newer codes, the first 2 numbers tell you the week of the year the tires were made. The third number tells you the year, but doesn’t specify the decade since it was assumed the tires would be replaced within 10 years

Make sure you check the DOT number on all four of your tires. Just because you bought them in a set does not mean they are all the same age. If you have trouble finding the DOT number, ask the service department at your dealership. The certified technicians can help you through the process of making sure you are driving on safe tires.

We recommends that its tires be rotated every 5,000 miles for normal applications. If your vehicle has a matching full-size spare tire, it is recommended that it be included in the tire rotation. After the tires are rotated, make sure they are inflated to the pressure specified by the vehicle manufacturer.
