Correct psi ?

[richy2]

I recently took delivery of a Dynamax rev motorhome. The label on the pillar shows 65 in front 80 for rear. When I checked, the psi was 80 all around. What should the correct psi be for this vehicle. Owners manual says to refer to door label???
Thanks for the information

Use the door sticker. Do take time to weigh off front, back, and each individual tire. My driver's rear was overweight so I spent the money for different rims. I did not have a blow out.

I now use a tire pressure monitoring system.

I thank you, dougrainer, for your informative answer to the OP question. I have noticed since I joined this forum (a long while back) your replies are very helpful. I have to think you are/have been a RV tech for years.

ALL motorhomes, the VIN/Door sticker will give the correct Air pressure for the motorhome as designed by the OEM. If you want more exact pressures you do the 4 corner weight program and then go to the charts for the weight per your motorhome 4 corner weights. The chassis owners manual is for the Incomplete Chassis build specs. That is why it states to consult the OEM added VIN sticker for the correct pressures. Doug

Maximum load = maximum sidewall pressure. Inflate accordingly.

Let me think on this one........ The owner's manual says check the information on the door pillar. The door pillar clearly has the correct tire pressure indicated. Now, what is your question again? I am having trouble understanding any confusion.

Assuming you have the OEM size and load range tire... 65 and 80 would be minimums and should cover the GVWR and GAWR. Often the pressure is adjusted up (not to exceed sidewall max) to improve handling or ride and that is fine too.

Are you having issues? You can certainly try 65 in the front to see if you like it better.

Cold is before you roll and before the sun is on them.

Pillar is correct unless you weigh the rig AND have the correct tire pressure chart for your tires

I don't think the dealer reads the owners manual LOL. Sounds like you got the answer I would go by the manual.

To be precise, you should weight axles, or preferable wheels and go to tire manufacturer site for inflation chart per load.
