Reasons for Trailer Tire Failures

Question:

I have a 1984 Holiday Rambler Imperial 31 tagalong travel trailer with 205-75r 14 tires and wheels. Is it possible that these 6ply tires arnt large enough for a 10000 lb camper? Should I switch to a 15 inch tire and wheel? The reason I ask is I had a Blowout and tore up the fender and lower panel on the right rear.

Tire failure is usually caused by a few things. It can be from overloading the trailer, improper tire inflation, and/or exceeding the speed rating for the tire.

You should verify that the tire capacity you have for you trailer is adequate for how much your trailer weighs. The weight capacity for the tire will be listed on the sidewall of the tire. The highest rated tire we offer in the 205/75R14 size has a 2,100 lb capacity, so if you have tandem axle trailer you would not have enough capacity.

The part # AM32680 has a 2,830 lb capacity and would work if you have a tandem axle trailer. You would need to have a 6 on 5-1/2 inch bolt pattern for these to bolt up to your trailer though.

The pressure ran in the tires makes a big difference in longevity too. ST tires should be ran with the full pressure rating stated on the side of the tire, for full load capacity and longevity of the tire. If lower pressures are ran the tire will heat faster and hotter and fail prematurely.

Special trailer tires are usually rated to operate at a maximum speed of 65 mph. If you exceed 65 mph, heat could build up in the tire and cause it to break down and fail. If a tire is rated to run at a higher speed, this information should be listed on the trailer's sidewall.
