Question Replace tires what size would fit? 10r 22.5 are not available

Hello … I’m a French girl living in Acapulco. Anyway I have this 37 feet 1990 Oshkosh Overland RV with Allison Transmission and Cat engine bought in 2009.
FRONT 09000 lb
REAR 16880 lb
GVW 25880 lb
My question is about tires. When I bought it, it had six Dunlop SP 160 9R 22.5 ->6.29
On February 2015 I bought 2 Michelin tires. Since I couldn’t find in Mexico City the 9R, I put on the front two Michelin 10R 22.5 XZE 14PR. Last month one of my rear tires broke into pieces. Once again I can’t find in all of Mexico 10R, I had to put an 11R which is much too high just in order to get back to Mexico City. I need to change the four rear tires but nobody seems to know which size would fit. It seems like RV tires can’t be importer unless they are on the truck. Nevertheless, some guys say they can do it but they want me to tell them exactly which tires I need and when I say “Michelin 10R 22.5 XZE” the answer is they are no longer available. Has anyone experienced this nightmare? What size of tires would you suggest? I like Michelin.
I resume :
9R 22.5 not available
10R 22.5 not available
Would 235 80R 22.5 XRV 16/32 tread 14 PLY fit?
Would 295 80R 22.5 fit?
Thanks for your help. Ceciilia.

If you wish to use Michelin tires.. I suggest you either call or email to their tech support on their web site.. I'm sure they can put you in touch with a dealer who either has the correct tire in stock.. or can get them from a warehouse....

I'd also suggest you look at one of the web sites and understand the age of your tires based on the serial # on the tire... there is a standard format for understanding how old the tires are....

best of luck..

Goto truck tire dealer. Ask them what metric size 22.5 is the same size/ Use that. No problem.

Tire Selector | Michelin RV Tires

275/70R22.5 at first glimpse is as close as you will get to a 10R22.5
10R= 40.1 tall and 10.2 wide
275= 38.0 tall and 10.9 wide

9R22.5 the closest I can see is a 235/80R22.5
235= 37.1 tall and 9.2 wide

Check on the 235/80R22.5 availability.

10R-22.5 looks like an "in between" size with no equivalent metric replacement. Many companies make tires in this size, but not all of them will be readily available at a given time. On simpletire.com, the Hankook AH12 is the least expensive tire with a reputable brand name.

If you drop your requirement for Michelin tires you will find plenty of 10R22.5. I replaced the 255R8022.5 Michelin tires with Continental HSR2 in the 10R22.5 tires. The Continentals are just a wee bit bigger. The speedometer was 3 miles per hour off at 60 mph. I subsequently had the computer corrected to show correct speed.

I replaced 10r22.5 on school buses with 295r75/22.5. The tire is a little wider. The ride and steering is better

I'm not expert in truck/rv tires, but the spacing between the rear duals is critically important. This pertains to the width of the tire [carcass] not necessarily the tread width. If one, or worse, both lose air the gap narrows as they "squat" and they can rub together generating excessive heat which can cause a blowout. One rear suddenly failing is bad, both failing can lead to sudden loss of control, not to say the damage to the undercarriage and body.

The tires on the steer axle can be a different brand and "slightly" different size then the rears, but ALL four duals need to be the same specs as each other. This may help you in locating a brand other than Michelin.

I would strongly urge you to consult with Michelin as to your options/availability. I didn't even mention load range, you seem to be pretty savvy.

Your present tires seem unsafe to drive long distances. Be cautious you don't want to cause damage to your "home".

Toyo makes 9R and 10R 22.5 M120 tires; I have no idea if they're available in Mexico but they're perfectly fine tires.

You can't just replace different width tires willy-nilly on the duals. What width tire is supposed to be on the MH?

This website is very helpful when selecting tires for dual wheel installation. Additional Tire Information | Pavement Interactive
An old rule-of-thumb for selecting tires for dual wheels is; 1.5" between tires at their closest measurement.
