Tire pressures

[2 Stroker]

January last year I got a new set of Michelin 295/80R22.5 XZA2 with a max PSI of 120lbs. I had my coach weighted at the FMCA Rally in Albany,Or (4 corner wt) and I'm over wt in the rear by 1150lbs and under in the front by 730lbs. With a combined wt of 33,620lbs FR 6,405lbs-FL 6,065lbs RR 10,195lbs-LR 10,955lbs I have to run 105 PSI in the front and 100 PSI in the rear. They give you a print out of your coach wt's and the air pressure to run. This is the only way to get a true wt reading and know what PSI to run, money well spent. Must be the new steel and brass radiator to be over on the LR and not the way the wife packed the coach

I have been reading what everyone has to say about tire pressure.So i went out to read the tire.I have brand new Michelins,we will be full time some time this summer.That means we will be full as can be.The tires say max is 130 on single and 120 on dual.Does this sound right?
We have a 40 ' monaco diplomat dual on rear.When we get it loaded i will take it to the scales to check axel weight.I did pull out the pressure gauge and they are at 100psi now,we only have full tank of fuel and propane at this time. I just want to be as safe as possible.
Thanks for all the input.We are very new at this also.

Heat is the number one killer of tires and reduced air pressure is one of the main causes of heat.

Why not go ahead and replace your tires, the next set will likely last the life of your coach with your luck with tires, and you won't have to deal with them on the side of the road. Just food for thought, good luck and safe travels.

There is another factor to consider. The maximum rim air pressure, which will be found stamped into the rim. My Alcoa rims are stamped 120psi max. With the latest information now being posted here, there should be little reason to run those minimum acceptable air pressures printed in load/inflation tables.

We have a 40' monaco diplomat and will be to close on max cargo capacity.
