Troubleshooting Boat Trailer Rim Getting Hot

Updated 07/10/2022 | Published 07/01/2022

Question:

I have a 2000 Ellis boat trailer and recently had a tire blow out. Once all were replaced due to age I noticed the rear rim was really hot. I took the trailer to a local shop and the brake and bearings were done. He replaced all the bearings and new brake pads and actuator cylinder. After driving it home about 10 miles I went to back it in and noticed both of the rear rims were very warm. I took it back and he checked that the wheels spin free when lifted with little to no drag. I drove it home and again they were pretty hot. I am wondering if this is normal, or what caused the tire to blow due to overheating rim. I appreciate any help you can provide.

More than likely your tire blow out was due to the age along with the current heat here in the summer. I'm not sure how old they were exactly but a tire typically lasts 3-6 years. A tire blowout typically comes from excessive heat from underinflation, overloading, exceeding the speed rating, or flat spots/sidewall rubbing.

Considering the fact that you took the trailer to a shop for replacement parts, and also had them double check once you noticed the heat, I would say you have nothing to worry about. You also know the brakes aren't dragging since you checked those yourself. Tires, wheels, hubs etc. will heat up while driving. I'm sure you are paying more attention to this after your recent tire loss so it was something you didn't notice before. The summer heat combined with your normal driving and braking are likely the cause.
