Michelin Tires (235/80 R22.5) XRV Question

[56Nomad]

My 2012 30' Itasca has Michelin tires (235/80 R22.5 XRV’s) that were manufactured in late 2011 and have about 32,000 miles on them. Apparently this size tire is only manufactured by Michelin.

If I go with a Michelin replacements, I’ll only need (5) tires, as I replaced one of those Michelins with the same when I had a sidewall damaged on the road about 4 months ago.... so I have one new tire on the rig.

There is plenty of tread left on the tires, but they are pushing 6 years. I'd like to find a compatible and less expensive tire to mach the single (235/80 R22.5 XRV) Michelin. I'm reading that*Michelin size is weird...their 235/80R22.5 is a 245/75 R22.5 to everyone else, but I don’t know if that is a fact.

I've also was told at Discount Tires that (1) 235/80R22.5 Michelin cannot be run with (5) 245/75 R22.5 Toyo's front or back duals. They also said that the Toyo 245/75 R22.5 are a little fatter and may rub as dual rears. A Michelin tire is $600 and the Toyo tire is $305.

Has anyone had problems in switching to Toyo's from the Michelin's?

Thanks

Lots of folks have moved from Michelin's to Toyo and others. I moved to Firestone FS591's.

I like Discount Tire very much, but don't think they do many large truck or RV tires. I would suggest you find a properly experienced shop.

The odd tire should not be run with another in a dual pair, nor on the front of course. Suggest to buy six matching and sell all existing on Craigslist. The newer one will be worth more than the others. I sell my takeoffs usually for about $50-$100 or more each, age and condition depending.

This may not work for you...I bought 6 Michelin's 235/80R 22.5 from Costco and had them installed at a truck shop for $20 each. I don't remember the price at Costco but it has most likely gone up like everything else. I know it's not the same, but I put Bridgestones on my Tahoe (from Costco) and I'm really not happy with the ride or performance. Plus they sound louder than I remember with the old Michelins. It seems to be some kind of law, whenever I try to save some $s it comes back to bite me.

Good advice. I replaced my Michelin 235/80R22.5 with Toyo 245/75R22.5 about a year and a half ago. I can't tell the difference in the ride or drive. No problem with the slightly wider Toyos, and I can't really tell the difference in the speedometer even though the Toyos are a hair smaller in diameter. I'm happy.

The Michelins I took off were all at least 7 years old. One of them was a 2003 model (this was in 2015). It had a wide crack on the inside sidewall, but had never lost any air. I think I got it off just in time to prevent a blowout!

Replaced my Michelins with Toyo 245/75R22.5 4 yrs/10K miles ago. Working great. Carry 90 Lbs in all 4 tires. Had 4 corners weighed, added 10% from recomended pres. and put em at 90.
I'm very pleased with ride, handling and lack of noise.

Here is a link to what I did over 3 years ago. Sure was glad to get those 235/80 R22.5 Michelins off the coach.

Tire-sises are rounded by the tiremakers , so your 235/80 can be in real 239/78 . Other tiremakers may round this the other way or their 245/75 is in real for instance 241/78 ,wich make them round it the to the other sise.

That can be what you heard about the sises .

So in real the difference can be less, and most likely the different sise wont be a problem for the space they take .

The larger truckkind of tire you have are often used more then 10 years, and then if allowed regroved a few times even.
If you let them be checked every year by a trustable tire-fitter ( so not one with dollars in his/her eyes) , you can use them also longer.
If that tire-fitter then says they have to be replaced , do that , but its then mayby after 12 years.

If you keep your pressure high enaug with comfortable reserve , the tires wont damage by driving.

but often for motorhomes the tires are yust enaugh for the weights they have to carry, so yust a little overloading or underpressure, can cource damage to rubber stucture. Once damaged , every bending of it by the about 10 times a second deflection and flexing back of every segment of the tire, tears the rubber a bit further , and mayby even after 3 years the tire is that much damaged that it blows and cources accident in the worst case.

That is why they advice to chanche them after 6 years, and St tires even after 3 years. All to cover the expected slow damage because of the to much heatproduction .

Your tires thoug , I estimate ( so can be wrong) can carry your loads easyly, so wont damage that way ( if you keep them on enaugh pressure).

the one tire you chanched , was damaged the way every tire can damage even after a month use.

How did you get the tires from Costco to the truck shop? I was looking at doing this, but manhandling 6 large tires was a show stopper. Costco prices beat everyone else's including the discount programs offered by various RV Groups.

I ended up going with Bridgestone Tires. I was so pleasantly surprised at the improvement in handling, and reduction in noise over the Goodyear tires that were on the coach.

My tire history is:

Coach new came with 235 Michelins. Front tires rivered bad in first 30,000 miles. During this time I had several allignments, balanceing, etc to try to correct this problem. Due to the fact that only Michelins make this size, on the next set I when up to 255's looking for a smother ride with less PSI. Changed fronts first, followed by all to 255's with about 60,000 miles. Not form or fit problems.

255 Michelins: No problem with fit or function. Speedo was off about 1%. Still had rivering on fronts. Again more balancing and allignment but still had rivering. Noticed cracking around tire rim. Changed front first but at approximately 120,000 miles had all 255 Michelins on.

At 180,000 miles After again more allignments,balancing still had rivering on fronts and sidewall cracking. I installed 265/75 154's Toyo's on front. No problems with fit or function as it is a direct replacement for 255's within .1 tenth of a inch (see tire comparison charts). Great ride and felt (seat of pants) more stable around corners (again seat of pants review). Ran fronts 25,000 miles (approx. 3 years) with no problems or signs of rivering. I am finally a happy man as far as ride, no rivering or cracks on the Toyo fronts. So at approximately 200,000 miles I replaced the 4 rears that had bad sidewall cracks with 265/75 Toyo's.

Now have 207,000 miles on coach and I love the Toyo's.

I'm not even going into pricing but the last 4 rear Toyo's costs $1390 out the door with me furnishing balancing beads.

Disclaimer (I'm the son of a lawyer): The above are my experiences and opinions based on my memory and 207,000 miles with my coach that I bought new.

Hope this helps with your decision.

In years past with a different motorhome on a Ford F53 chassis, it was Costco all the way for me. But with a Workhorse chassis requiring 475 ft. pounds of torque, Costco could only sell me unmounted tires. When I factored in the expense, time and effort to pick-up 6 tires in a U-Haul trailer and go to a truck-type tire store for installation, I just said what the heck and let the truck-tire store do the complete job. Plus, if there had been any tire issues, the truck-tire store would have put the blame on Costco and I would have been caught in the middle, renting trailers and shuttling tires back and forth. -RT

Your tire dealer should tell you if the Toyo will work on the duels. I don't know if this will help: https://www.toyotires.com/commercial...-position-tire


I love the Toyo's. Sad story. Bought Continentals for the front. Payed way too much for them through FMAC. Toyo is a great tire for all positions.
