You can know when your tire was manufactured.

Many people are surprised to learn that their tires have a date code on them. Before you head out on the road with your trailer, you should check the date of your tires. This is especially true if your trailer has been stored over the winter and has not being used.



Tires have identification markings which are designed to tell you exactly when the tire was actually made.

According to standards established by the U.S. Department of Transportation (DOT) National Highway Traffic Safety Administration (NHTSA), tire Identification numbers will be a combination of the letters DOT, followed by ten, eleven or twelve letters and/or numbers that identify the manufacturing location, tire size, manufacturer’s code, along with the week and year the tire was manufactured.

All tires manufactured since year 2000 will have a sequence of numbers that identify the week the tire was manufactured followed by the year.

Consider this example. If you see “the “DOT 334JF916” Identification Numbers of this tire and next to those numbers you see “3215” which tells you that this tire was manufactured on the 32th week of year 2015.

The entire Tire Identification Number is requisite as a brand on one sidewall of every tire. The first digits of the Tire Identification Number must also be branded on the opposite sidewall.  If you don’t see the whole identification number, look at the other sidewall.
