toad tire pressure

[kohersh]

What do you all think this could be? The tire temp on my toad has 1 tire that is consistently hotter than the rest.
When cold the Temps and pressures are all uniform but right now on the road the Rears are even at 95 deg and 40psi, but the front driver is 100@40 and the passenger is 113@40.
That's a big fluctuation and I've noticed it since installation of the tpms.

My first thought is alignment but I don't see any terribly obvious abnormal treadwear, anything else come to mind?

Probably due to more weight on the fronts than the rears.

Have experienced the same. I found it was the heat from my diesel exhaust
