Need to know how old your tire is? The Tire Identification Number can tell you. Where can you find it? What do the letters and numbers mean?
"DOT" stands for the U.S. Department of Transportation. Displaying this symbol means that the tire meets the National Highway Traffic Safety Administration (NHTSA) tire safety standards. The DOT serial number is located on the sidewall near the edge of the rim. DOT is followed by a series of digits that identify where the tire was manufactured, size, and the specific code, along with the week and year the tire was manufactured.
The first two digits are the week of manufacture and the second two digits are the Year. As you can see in the Example the tire pictured was manufactured during the 34th week of 2019.
This is important information for your safety. We have all seen the carcasses of tires on the side of the highway. Many times this is due to old tires that should have been replaced failing while driving. if your tires are 5 years old or older they should be considered for replacement.
