I installed a TPMS and was surprised by the wide variation of tire pressures that result from tire temperature changes. I filled my tires to 82# as stated on the coach sticker at probably 65 F. But on a cool morning they may be as low as 78# and after running on the highway, up in the 90's. On a hot day they will exceed 100#. So.... if you "cold inflate" to 82#, but the tires are normally running 10# or more higher, aren't they technically "over inflated".
IMHO, seems like we may be obsessing a bit much on tire pressures.

I agree. I'm going to fill at the recommended pressure on the sticker and put it out of my mind.
