Air Pressures?

[Braz]

We just got our first RV, a '99 28' Jayco Eagle. The door decal on the Ford E450 chassis shows the recommended air pressures as 65psi front and 80psi rear. Are these good pressures considering that Ford did not know how much the "house" would weigh when they came up with the recommended pressures?

Thanks,
Braz

The best way to determine the correct tire pressure is to load the coach and then drive across a CAT Scale (for point scale would be better if one is available). Once you have the 4 point or individual axle weight then go to the tire manufacture's recommendations for tire pressure for weight. My prior coach the weight based pressure was 5 psi below the sticker recommendation which also resulted in a slightly smoother ride going down the highway.

Most definitely. We had the same experience with our 01 DESIGNER and 08 SENECA.

Thanks for the advice guys. A nearby Pilot truck stop has a Cat scale. I don't know if it will weigh individual axles or just the whole rig though.
