New to this forum, I recently purchaced a 32' SuperChief. I had to replace the front tires because of inside tire wear. After much time searching the net, I have found that if there is not enough air in the front bags, inside tire wear is bound to happen. The books inform that the rear are 90lb max but nothing about the front bags. Also what is concidered the correct ride height? The books say nothing of ride height. Any help would be greatly appericated!

When I had a coach with that chassis, I always ran 90 - 95 lbs in the front air bags. Mine was 34 foot long. When the bags start leaking and need to be replaced, you should consider replacing them and the springs with new springs. Then you will not need air bags.

We had a '97 Trek with this chassis and it had the air bags in the front also. Rex is correct on the air pressure in the bags. 90 to 95 typically when the coach is loaded and ready to roll down the road.

On the ride height, I looked at a newer same type of moho and noticed it was pretty much level front to rear. Mine on the other hand was definitely sagging in the front. I was planning on replacing the springs with newer heavier duty ones because the bags themselves wouldn't level it no matter how much air I put in them. We traded up to a newer moho before I got around to it.

Is it true about not enough air pressure in the front bags will cause inside tire wear? The coach is in great shape, but I don't really want to throw a lot of money into it that I won't ever see come back when we decide to trade up.

Michael,

Check out the following link on the P30 chassis and note the section on air bags on page 10.

Thanks Neil, took longer to download then I thought it would. That doc. is good stuff. It will help immensely. Thank you for you time in this matter. I bought this coach from my father last year, and have been trying to get it road ready, not much care was given to it after the passing of my mother 10yrs ago. It only has 65k on the coach, and about 12k on the motor. AZ sun has done its fair share to the outside, and I am in the process of cleaning it up the best I can. Again thank you so much.
