Driving right at 65 mph and already having dumped, so running medium weight. Temp on my mirror was high-90's. I've also noticed that running the heavier tires at max psi makes tight turns a lot easier, with less creaking and groaning from the suspension, since the harder tires slide a bit easier. FWIW, were I to clean out my FW totally, and run light, I'd probably run at 70 psi...just because.

If they side in corners easier, then they will side under braking easier! That is one of the issues that Michelin pointed out to me about over inflation. Decreased braking!
Did you check the temp of the TV tires at the same time you checked the trailer tires. At what temperature were they running. When I run from Phoenix to PS in 90 degree weather, my truck tires are around 125 and the trailer tires 119.

Me thinks running MAX PRESSURE blindly is the way to go. Says so on the side wall!
