tires for my 1999 DSDP 3884

I am look at buying 6 tires for my 1999 DSDP 3884
I weighted the RV Front 9600, rear 15900 total =25500
I have on Front 275/70/22.5
I have on rear tires 255/80/22.5
Can I put 275/70/22.5 on the rear, (so I would buy 6 all the same? )
I am looking at the Michelin inflation charts for rv usage only

Am I reading this right? That I could use 85 psi on the xza2 energy for all 6 tires?

This link should give you the information you need.
Do you have a sticker on drivers wall with weight limets and tire size on it.
The front tire size may have been changed because of better foot print on road surface.
Your weights should indicate in tire pressure table what psi should be.

The reason you have different size tires is your motorhome came with 255/80R22.5 tires all around and the front axle was near or over weight. Newmar along with Spartan and Freightliner replaced the front tires with 275/70R22.5 on the front only to increase the front axle capacity from 10,400 lbs to 12,000 lbs.

You can use either 275/70R22.5 or 275/80R22.5 tires all around. The 275/80 tires will give a smoother ride.

Apparently FMCA has worked out a deal with Michelin on MH tires. You might check out their website and see if it would make sense to join if you aren't already a member.

By the way--I found that it makes sense to call around at different cities to get prices. I saved $ 450 this way. I called Michelin dealers in central Texas and found that there is LOTS of difference.

It's called the "Advantage program". Most Michelin dealers can do it. Basically you buy the tires, pay with a credit card and then a few weeks later you get an invoice direct from Michelin. The dealer doesn't even know what you pay. There's an announcement about it on the FMCA site.

My coach was in the same recall for under rated front tires the PO, replaced the rears to match , all 6 tires are now 275/70R 22.5 Michelin. rated at 6940 lbs @ 130psi single . after getting a fully loaded for travel weight; full of fuel is important here; and consulting the inflation chart I'm running 85 psi rear and 95 psi front , ride and control good. Weights are written down in the coach some where, as is my copy of the chart; packing in progress; I know my travel weight was higher than your 25,500 I just can't get the info for how much. I consulted the charts and came to the pressures listed above.
Safe travels.
