This is bad advice and can be dangerous. The ONLY safe method to adjust PSI is to load the MH for travel, weigh 4 corners or at least front and rear and set the cold PSI to the tire manufacturers instructions. Guessing can cause tires to be underinflated and cause serious issues.

Just for your info he has another thread and his specs say 80 psi for the tires from Fleetwood and I also have owned 2 Fleetwood motorhomes with same size of tires and his same length/weight and 90 psi rides hard and 80 psi rides softer and is at factory specs..

So Fleetwood needs sued for BAD ADVICE you saying.. :o

So by your reckoning, all Mh's of the same length on the same size tire can all run the same PSI? Let's ignore the weights, how they are loaded, the brand of tire and a bunch of other factors. Length and tire size is all you need. Who knew? And here all this loading and weighing and 4 corners and manufacturer charts is a waste of time. Thanks!

I would lower the PSI by 5 PSI and see what that does. I've seen amazing results by just lowering tire pressure a little in ride quality.

Considering upgrading from my 2002 31' Fleetwood Fiesta to a 2007 Hurricane (Thor/Four Winds) 34B. Hoping for a smoother more stable ride. I've owned the Fleetwood for 2 years have added stronger control arms, Davis stabilizers, Safety Plus steering stabilizer, new Bilstein shocks, new tires, etc.. The ride is heads and tails better than it was but. The coach is stable but the ride remains stiff/rough on the poor CA highways. Looking for a softer smoother ride without sacrificing any stability.

Not sure if you're going from Ford to Ford or WH to Ford, but either way, you're talking a straight I beam axle on leaf springs, so....
I'd say that you should be looking for the least amount of overhang behind the wheels for handling and tire pressure can only be determined with a weigh in. I never bother with four corners and just go with the axles and then add about 10-15psi for a cushion and for taking care of all the variables.

What is puzzling is mine is also built on the Ford F53 chassis. The previous owner replaced the tires in 2014. On the sidewall of the tires it says minimum air pressure is 100 lbs. On the placard on the drivers side wall it says 80 lbs. I think I'm going to post the type of tires and ask for feedback. It may very well be I've got cheap hard - overinflated tires causing the rough ride.

Sorry, that is NOT what it says on the side of the tire. It will say carrying capacity of XX at YY PSI.

If your tire is not carrying XX, you do not need YY PSI.

Go get your coach weighted-- individual wheel position weights are best. Then go to your tire manufacturer's inflation table to determine the minimum PSI for that weight (all tires on an axle get inflated based on heavier wheel position on that axle). Most of us add 5-10 PSI to that minimum.

The GVWR sticker by the door will give PSI for the coach WHEN EACH AXLE IS LOADED TO GAWR. Are you that heavily loaded? If not, that may be over-inflated.

My 30Q, 2009 Hurricane, was the best riding-driving Class A I owned. I had a Winnebago Sightseer and Georgetown both approximately same lenth and had to put Steer Safe on both of those. My Hurricane was on a F53 chassis.
