Troubleshooting Reasons for Trailer Tire Failure

Question:

I have a 2014 jayco 361reqs that came with 235/80/16 tires. I had a blow out and dont know why. I check tire pressure every time I tow the fifth wheel. I run 80psi in the tire.all the tire Ive seen say a max psi cold. I have test my tire at fuel fill ups and the heat makes the pressure go up. Is that Okay? Thanks

Pressure wise you are fine. You always want to keep trailer tires inflated to their max psi. Inflating them when they are cold is recommended even though the pressure will increase as they warm up.

Typically failure is related to heat build up which can come from under-inflation, overloading, or exceeding the speed rating for the tire. Most trailer tires are rated at 65 miles per hour as their max speed so you would want to check the sidewalls of the tire.

It could also be related to the age of the tire. If it is older than 7 years we recommend replacing them.
