Some time back a poster was converting his rear wheels from dual to single mount tires. As I am looking to replace the rear tires on our coach I am interested in doing this as well. The problem I have encountered is that the only single mount tire I can find that might do the job is the Michelin X One XRV. The rear axle on our coach is rated at 23k lbs and weighs about 20-21k loaded. (I have weighed it several times) The 445/50R22.5 LRL is max rated at 10,200lbs at max inflation of 120 psi. That translates to 20,400 lbs for the axle, and leaves me 2,600 short of max capacity. The current tires, G670RV 295/80R22.5, are max rated at 27,760 lbs which is comfortable for me. I hate running anything to the limit of its design paramaters. I also need to get the ratings on the wheels they would be mounted on too. Anyone know if they make aluminum wheels that big? I've tried a few tire sites with no luck on getting that info. I really hate to call a local tire shop because they many times know less than I do!
I noticed lots of OTR trucks using them on aour last trip from So Calif to Mo via Sacramento last week.

In the 70's we had a Chinook class C which had "super singles" on it instead of duallies. We bought it used so I don't know if it came from the factory like that and I can't remember the brand but I soon noticed that on trips the sidewalls got very hot and the handling was poor. I'm not a pro. driver but I could tell it swayed from side to side in the rear on Calif. mountain roads. I had them replaced with Goodyear Super Singles and that fixed the problem. Cool sidewalls and noticably better handling.
These were 16" tires and not 22.5's but you might want to talk to other owners before you invest in wheels and tires. It still might be possible to get bad ones like my first pair. Also, Goodyear may not be the same company it was back then although the ones on our MH seem to be fine.
I never did carry a spare for the super single because I figured I could make it to help on the spare I carried for the fronts (which were not on dually type wheels, BTW.) I guess few people carry 22.5" spares so this wouldn't be a big issue.

Hi,
There are no on-road tires that will give you much over 10,000 lbs each. Simply because the law will allow a single axle to be only loaded to 20,000 to 21,000 lbs . This is true for all states. At this time there is not much enforcement for non-commercial vehicles .(PA and OHIO turnpikes will turn you back).

Make sure the super singles and their wheels will clear you brake ddisk/drums.

Is there an alternate solution that uses single tires on the rear rather than duals.

You are over the legal limit for a single axle for use on Federal Highways. Reduce your weight or stick with what you have. It'll still be illegal though, just not over the tires' limit the the Michelin would be.

Claimed better MPG, better ride and cheaper tire cost over the long haul. Of course you have to amortize the cost of replacing the duals. As I remember it was about 3.5K for two including the rims. Never could figure out what to do if I had a flat on one in the middle of the Navajo reservation or any one of a 100 other isolated spots we travel through or to.
