All ActivityMost RecentMost LikesSolutionsTire Pressure QuandryI have a 2003 Fleetwood 24' Class C RV. I purchased it used with almost new tires on it. The Ford cab door jam sticker indicates LT225/75R 16E tires (front and rear) with Front @ 65PSI and Rear @ 80PSI. The Fleetwood sticker inside the closet door in the RV indicates LT225/75R 16E tires (front and rear) with Front @ 65PSI and Rear @ 60 PSI. Normally, I would go with this recommendation, BUT... I just realized (after a year!) that the tires on the RV the previous owner put on are actually LT215/85R 16E! I don't know how much difference this would make in the amount of PSI I should use in these tires, but would appreciate any input forum members would care to offer. Thank you for your help.
