My sticker has 90psi but it also says I have 22.5" rims, the coach has 19.5" fitted rims.
I run 87 front and 89 rear and it rides fine. 110 psi is on the tires and that is like driving over cobblestones.
The correct way is to weigh all 4 corners and follow Goodyear's recommendations for the load on each tire (front) and each dual (rear).
