correct tire pressure

[boundersteve]

We are new to a 2007 Bounder 33R on Ford 53 Chassis. I had it weighed today and worked out the inflation pressures. My wheel position weights are: Front Right 3,420 - Front Left 2,660 - Rear Right 6,760 - Rear Left 5,820.

So per the Michelin tables, it would seem that proper pressure for the front axle is 70psi, and rear is 80.

I am reluctant to run different pressures front versus rear and I'm thinking about using 90psi on all wheels. Any advice appreciated.

I would see what you could do about getting the weights of the wheels on each axle closer to the same, ie., jocking some stuff around in the bays.

There is no problem running different pressures on the front and rear. The only problem with running the higher 90# pressure is that it will give you a harsher ride.

As wackymac suggested I would try to distribute the weight more evenly.

Good Luck,

My coach is about the same size as yours, 22.5 wheels. Set mine up per the Michelin chart 70 and 75. Great ride handles and track well. One time I set the tire pressure to 80psi front and rear, ride was harder and the coach did not track as well.

I also wonder about the same thing with tire pressures. I am running 90 psi in the frontand 95 psi rear even though the door sticker says 85 psi. When is the tire considered under inflated?
