When I first got my 34 ft, I ran 105 psi in the front tires just like my previous heavier 40 ft coach. I thought the coach needed a front end alignment because it seemed to need a lot of corrections, especially on crowned roads. Called the FOT alignment guy and he told me to weigh the coach and set pressures according to manufacturer's specs for the load before I brought it in. I did, and lowered pressures to 90 psi. What I thought were alignment problems disappeared with the new lower pressure.

Have a friend with a CC the same age and size as my 95 U295. He runs 100 to 110 in all tires and complains about having to "chase" the wheel constantly. I run 85 to 90 and have no problem. I know, I know, I have a FT and he has a CC.

No wandering or chasing here unless I've had a margarita or two and with the DW in the right seat, I don't do much chasing anymore! Failure to go straight down the road is usually alignment and not tire pressure. A little toe in generally is all that is needed. Some tires brands/models DO seem to track better. Worn shocks with different rates also will make a coach move from side to side depending on the road.

I know this is an older thread, but wanted to thank you all for posting it and commenting on it!

One of the tire shops I have been working with just called me and suggested the Uniroyal RS20 as a good load range H tire to replace our aged out tires.  The Michelins I wanted aren't readily available in our area in a load range H.  The price on these Uniroyals is much less than new load range G Michelins through the FMCA program.

I am very grateful folks have shared their experience with this tire.

With a 36' coach you will probably be ok with the load capability of the Uniroyal.

Check the load charts on Uniroyal. The H rated Uniroyal chart shows it carries less load then other major brands H rated. 

Uh oh question on tires

Michelin does have Load Range H in their tire model that superceeds the XZA+.

Dan and Barry,

Thank you for your replies and helping to ensure we don't get into trouble with the tires.

For archives and searching purposes I've included the inflation table for 270/80R22.5 tires from page 18 of the 2018 Uniroyal Truck Data Book below, and a link to the PDF.  The 275/80R22.5 tire capacity exceeds the GAWR of the front and rear axles on our 1998 U-320 36' (12,350 lbs front GAWR, 20,000 lbs rear GAWR).  The tires can carry 870 lbs above the front GAWR, and 4,000 lbs above the rear GAWR.  The RS20 will do the job with a bit of margin, and hopefully that will help the tires run cooler.

We're replacing all six tires, and we aren't full time.  The tires will age out before they wear out.  The RS20 seems to be a good balance between capacity and cost.  When buying six new tires, the RE20 is a significant savings over many of the load range G Michelins available through the Michelin Advantage program.
