I 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.

You should be able to find a tire pressure chart for the brand tires in use on the Internet. Using the axle weights which should be on the Fleetwood sticker you should be able to locate the correct tire pressure.

Your 215/85R16 Load Range E tires take, and require, the same pressures as 225/75R16 Load Range E tires.I stopped using what my 24 foot Class C came stock with when new - 225/75R16 Load Range E tires - two tire replacements ago. 215/85R16 Load Rand E tires are about 1.1-1.2 inches larger diameter (but they are slightly narrower width) than are the stock 225/75R16 Load Range E tires.I prefer the taller tire for more ground clearance. Also, my Class C's chassis is an E450, which has slightly lower rear differential gearing than an E350 chassis. The taller tires offset some of this lower rear differential gearing so that E450 fuel mileage is improved a bit up towards fuel mileage of an E350 chassis.

There should be weight rating/recommended pressures printed right on the tire sidewalls.....at least there is on mine.

My KINGDOM for a STICKY on this! Ford and Fleetwood applied stickers that cover the maximum weight designed into the unit (chassis for Ford, coach for Fleetwood). Highly unlikely that you can get near that loading in a 24-foot coach unless your camping trips include delivery of watermelons or car batteries.Which is why we need a sticky. The correct answer to all this is to weigh your coach, configured, loaded, fueled, populated, for actual RV travel and use. If you have access to a scale that you can get the four corners onto individually, so much the better. But it's more than adequate to use the CAT Scale found at just about every Travel Center... Pilot/FlyingJ, Love's, T/A and all those. If you tow a vehicle or trailer, have it hitched up too. For $10 you get a legal- for-trade weight slip showing Steer, Drive (rear of your coach) and Trailer.Take a tire pressure chart such as Michelin's and adjust the pressure of the pair of fronts, and all four rears, to the numbers in the chart. You can use Michelin for other brands because the specs are industry standard. Notice the first two sizes are the ones discussed here and they ARE the same as Phil noted. If your tires are hot by the time you get to the CAT scale, I suggest you use the charted numbers plus 05-PSI. Then adjust to what the chart says when the tires are cool and shaded the next day.Which Chassis do you have, E350 or E450?
