By the nature of their construction, all trailer tires will generate more heat. One way to help combat this is to keep your speeds down to 60 or 65 at the max (especially since that's the max speed the tires are rated at). You may also notice a difference running on blacktop as opposed to concrete because the surface temps on the darker surface should be higher than the lighter colored surface. My tires run 90 to 94 psi, and I would expect higher temps if the ambient temps are higher, but even that is subjective. For example, if the ambient temp in the morning when starting out is 70 and later reaches 80, I would expect less change than if the temps reached 100. Remember, all tire manufacturers state cold tire pressure, but that is for wherever you happen to be at the time. If you left Minnesota at 10 degrees with 80 psi and drove to Texas where it was 110, you are going to have pressure issues!
