Anyone have those fat tires one their mh in the back instead of duals? There’s a 9 yo thread with some positive feedback. My tires are aging out and was thinking about going to the single wide rears.
If you use them, post your thoughts.

I've talked to a few truck drivers with them. As with most things, some like them some don't. The rock truck company only uses them on their pups, one oil tanker driver had them and said the traction wasn't as good. Newmar tested them and still uses the standard duals. I had my first flat ever on an RV in late 2016. Outside rear dual. Was able to slow down and limp off the freeway. Could not have done that with with the single rear tire.
I'll stick with the standard setup.

Actually the point is moot for me as my tires are 19.5’s not 22.5’s. I would need 395/40R-19.5’s to keep the circumference correct. I should have double checked my tires before posting.

-Ruan trucking did some of the orginal testing for 18 wheelers. I knew the mech. snd he reported that most of the time you lost a tire (flat ,road haz. or what )you would also loose your rim due to damage to it . At that time they cost twice the cost of anew tire. The trucking ind. has not made a beline fof this tire. (no fuel saving ,more danger,less places to get serviced ,it goes on and on.

I've never seen them on an RV anywhere in the country. Not a real popular item.

If a rig doesn’t come with them on, it’s expensive to upgrade!
New wide tires cost more than duals. And the rims are up towards $2K each.

It's mostly tanker trucks using them now. It's called the Michelin X One.
They are reporting up to 10% mpg improvements as well as weight savings.
The company we spoke to had a fleet of trucks and had not ever had a flat with one.
If I needed new wheels and tires anyway, I might consider them.

Current sizes are:
445/55R22.5
440/50R22.5
