Running with less pressure than needed to allow for heat buildup is foolhardy and the flexing caused by the soft tires actually causes pressure to rise to dangerous levels, as well causing catastrophic tire failure. Inflating tires to proper pressure for the load on THAT tire will prevent excess pressure buildup caused by heat.

Yupe, thats why they are at the pressure they are at....Had it weight at the sandpit and those should do it.....Went that way after the sticker said one thing, the tires another. I could just go with the max on the tires at 80 lbs but its one hard ride on the back roads......The tires I took off it ran at 55 lbs since 94 and long brand new. Those were the Michelins, but felt better with the stiffer side wall of the Bridgestones....
Fine out tomorrow when we leave for the west.....
Truthfully, If I didn't feel safe, I would not use it at all, which is why I changed them to start with....They looked new, but I know they were not.....Tnx for all the replys....

Ugo,

I also have a 24 foot unit - a Coachman and have similar problems with a rough ride on some roads that do not appear to be all that bad.. I think it is the short wheel base and not the tire pressure. I have been running mine with about 78# all around just a little under the 80# maximum. This is over what the ford sticker calls for but that does not factor in all the extras Coachman added on.

I'm running 70#s up front and 80 in the back. Winnebago put a sticker on the drivers door frame that recommends that pressure. I figure the RV manufacturer should know what the right tire pressure is.

Once, I drove it and the rig felt like it was riding on Jell-o. When I checked the tire pressure I fould them all about 15 pounds low. Once I got the pressure back where it should be the rig handled easier, like it did when a I first got it.

I have a 1994 Ford E350 Class C Itasca Sundancer 500 and I'm a new class C owner.
My manual says 65# in front and 60# in the rear duals.
Should I follow the manual? Thanks

I carry 80psi all around on my 31'.
Michilin xpx rib tires.
Ride is a bit rough but until I get weighed I'll keep max pressure.
