The stickers show the GVWR and the tire pressure required to support that weight with the OEM tires as shipped. Federal Law.
Except when they issue you a modified sticker like we have due to the axle change. And since I went up to a 305 from a 275 that sticker is wrong now.

That's correct, so go by the tire sidewall and Wheel RIM pressure ratings. Don't forget about the RIM... It too has a max, and its max may be less than your tire max.

I imagine you and Robin are still in too much of a hurry to periodically weigh your coach at the CAT scales common found at many truck stops. If you don't want to weight your coach, you should use the tire pressures stated on the manufacturer's placard. Unless you've changed tires, the placard pressures should have been established to support the maximum weight for each axle. This way when you have a blow out you can feel safe knowing the tire blow was simply an early warning that you had an axle with too much weight on it.

BTW, how's that CR-V ride with 35psi in the tires.

This whole thing about tire psi is so silly. People wake up with nightmares over it. Set the psi to what the maximum is minus 5# and forget about it unless your're over the vehicle's gross weight which then, the psi no longer matters.

If something happens to a tire, I'll know it wasn't due to under pressure, and since I keep it 5-10 psi under max it will not be due to over pressure. So. I'll ride on the safe side.
Batman, you have a beautiful coach there and I'm happy that your formula for setting tire pressures works for you.

On my coach, however, 5# under the max psi on the sidewall or placard is >18% above the pressures defined by Michelin and will literally jolt the fillings out of my teeth. I know. I've tried it. So please stick with what works for you but don't tell me I'm "silly" for wanting to get the pressures right on my rig so I can enjoy my ride as much as you enjoy yours.
