Check your inflation against the plaque placed on the coach by the manufacturer. NOT against the tire manufacturers "chart".
The tire manufacturer has no way of knowing what vehicle the tire will be placed on.
I was shocked when I compared the ride and handling back to back with 85 in front and 80 in the back cold pressure the coach manufacturer called for vs 100 all the way around per the rating of tire.
Gone was the wandering weaving and hard edge feeling of the bumps and ridges and my coach rode like an escalade compared to a bicycle on the rims.
Interestingly I didnt notice any change in economy either.
Why not try out what the guys that built your rig think-? ( I think you'll be happy.)
