How to Read Date Code on Trailer Tire to Determine Age

Question

Question:

I have a set of hi run tires on my travel trailer. I cant find any place where my codes tell me the age of the tire. I show DOT 0J 20 FB1. How old is my tire?

The DOT date code on a tire is 4 numbers. The first 2 are the week and the last 2 are the year. So for example if it was 2314 that means that tire was made in the 23rd week of 2014.

Based on what you listed I do not believe that is the date code. Look for a 4 digit code of all numbers instead.

It is for the type of tire. Any tire with an R is a radial tire. If you see a D instead, such as the Loadstar ST185/80D13 Bias Trailer Tire w/13" White Modular Wheel - 5 on 4-1/2 - Load Range D, part #AM3S333, it is a diagonal or bias ply tire.…

Trailer tires do not have to be balanced due to the fact that you won't be able to feel the imbalance in the vehicle. Every tire and every wheel has a high (heavy) spot and a low (light) spot. When the manufacturers mount the tires on the wheels,…

There could be a number of reasons your Karrier Tire & Wheel #AM31985 is not holding air, but I'd start with the valve stem, as it may be loose. What I'd do is spray soapy water on the valve stem to see if it's bubbling to verify if…

You should be just fine with your tires and rim part #AM31985. Visually inspect them and make sure they are inflated to their max psi rating (65 psi), and you should be good to go. If you were planning on storing the trailer for more than just a…

Answer 11

The maximum life span of a trailer tire is typically 5 or so years, so you're absolutely correct in thinking they should be replaced. They're probably pretty cracked up and dry-rotted at this point. If at all possible, I'd go with the…

Answer 12

What size tires are you referring to? What's the GVWR of the pop-up? In order to achieve their listed weight capacity, most trailer tires need to be kept inflated to the pressure listed on their sidewall. If a lower pressure is used, the tires…
