Michael,

This brings up an interesting point: Newell recommends running 130 psi in my front tires which are 315/80R22.5. I realize that they are covering their butts and also that everyone loads a coach differently.

I had my coach weighed at Newell and the front axle weights totaled 16,750# or 8,375# per tire. The tire chart from the manufacturer shows a pressure of 121# for a single axle weight of 8,375. Actually, it shows 120# for 8,270# and 125# for 8,810# of weight. I just interpolated to arrive at the 121#.

So for my particular coach I should be running 121psi in the front tires. For safety I run 125# in the fronts. So it looks like for me, changing to 365s would be a waste of money.

I attended a seminar that Goodyear put on and they said that if you run a tire at less than 20% of its correct pressure you damage the sidewalls and should discard the tire and replace it with a new one!
