Was on a four day trip this past weekend and on the way out I stopped at a truck stop that had a Cat scale. So I got the PC weighted. I had 3/4 tank of fresh water, and LPG, both black and gray tanks were empty, Myself at 240 lbs, my wife, she would say her weight but she is 5'7'' and just slightly over weight and our 120 lb German Shepherd dog in the motorhome while being weighted.

The results are:
              Door sticker       Cat scale      difference
Steer axle    5000                4640            360
Drive axle    9600                 8140          1460
Gross        14,500              12,780         1720

How I need to call Michelin and find out what PSI to set the tires at. My guess is what it says on the door sticker.
Just thought some of you might like to know.

OK I found the load charts on the Michelin web site and looked up what they say for my weight divided by 2 to get each tire. Based on that I should put 65 PSI in both front and rear. I then called Michelin and talked to them. They want each wheel weighted by it self because there could be a big difference between each side based on the layout of the motorhome. So they say to put what ever the door sticker says in each tire. My door sticker for both Ford and Phoenix says 75 front and 80 rear.

Tom, that is excellent data for a 2552 owner.   ThumbsUp
A "Helpful Ckicky" for you.

I keep procrastinating doing that.  Each year we head out, I promise myself to get the rig weighed, but it unravels quickly.
I recall the door sticker on our 2007 2350 (no slide out) states 60 rear, 65 front.  But I add 5spi more all around to be extra careful because the tires still look like they could use some more air.....even more than 5 psi.

We picked up our new 2015 PC 2552 last week and I thought it might be helpful to others reading this forum to report the unloaded vehicle weight of our unit. I took it to the CAT scale before we started loading it up with the normal cargo you carry for a trip. The unit had a full tank of gas and a full tank of propane. I was also in the unit (150#) when it was weighed. The front axle weight was 4,420 lbs. and the rear axle was 7,760 lbs. for a total of 12,180 lbs.

FWIW,
Our loading is roughly equivalent to others reporting.
I had the faulty Michelins replaced with Michelin XPS Ribs. After approx. 7500 miles, I can see the edges are not always in complete contact with the ground as they exhibit a distinct difference at the edges.
Generally, I inflate the rears to 75-80 PSI and the fronts 70-75 PSI.
Judging from just the wear pattern, I believe I'm over inflating the tires by at least 5 PSI, probably closer to 10 PSI.
Consequently, it is entirely possible 65-70 PSI all around might be a better choice, which I'll use next season while watching the wear.
Summary: 80 PSI is clearly not appropriate for my unit.
