When we leave Chicago for Florida in January I used to panic about the tires in our old Class-C, that was what the dorian system was originally installed on and when I first realized just how much pressures fluctuate under different conditions.

Now I'm with Brian. If it is 0 to 20 outside leaving and my pressures are 90% of where they should be we are out-a-here.

IMO most of you guys over inflate the damn things anyway, little bit a cold air do um a world a good.
