Do Aluminum Wheels Run Cooler than Steel  

Question:

Expert Reply:

Aluminum does do a much better job at dissipating heat than steel, so to answer your question an aluminum wheel would run cooler than a steel one.

In a trailer rim application this really wouldn't be much of an issue though and wouldn't offer you any benefit. Rim heat isn't usually a concern on a trailer so using an aluminum wheel isn't offered as a recommendation for helping remove heat. The real benefit to aluminum wheels is that they don't rust and they are typically lighter weight.
