We have a 38 ft Coachman Class A gas
The tires we have on the unit now are Michelins XRV
Size 235/80R 22.5
The tires are 8 years old therefore I should have them replaced.
Mileage on the tires are only 6,400 miles.

I live in Canada and have priced Michelin same size: 235/80R 22.5 but
they price out at $558.00 each plus installation and balance.

Because we only put on only 800-1000 miles per year on the motorhome a year I also priced out the following:

LONGMARSH 16 ply but the size is a bit different:
Size is 275/70/22.5
Price is $259.00 per tire plus installation and balance.

Would the size difference be a bad idea and has anyone had experience with
LONGMARSH?

I know nothing about tires therefore am looking for advice.
Should I stick with Michelin our go with the $259.00 Longmarsh?

When my present MH was new to me the tires had aged out. The installed tires were a slightly different size than listed on the OEM 'placard' in the MH.

An internet search showed a limited choice of tire for OEM size but more than 30+ choices. This provided a large range is price for the same load capacity.

That is only a 3.5% taller than the 235/80. It would affect the speedometer that amount, but the ecm could be reprogrammed to correct it. The bigger concern is the clearance between the rear dual tires and possible clearance of the steer tires when turned.

Look at Hankook. They are getting good reviews for motorhomes.

Many tire makers offer a size that is almost exactly the same dimensions as the OE Michelin tires you are replacing. Search for 245/75R22.5 .

I would NOT try to use the size you posted. That size is likely to be too wide, which can create problems with the required minimum spacing on the rear duals, and may even contact steering members up front.

Also look at Toyo. But your Michelin price sounds high to me. I recently bought that exact tire for $500 installed.

I'm pretty sure 235/80R 22.5 size is unique to Michelin and the cost can be a bit hard on the RV budget. Changing size isn't difficult as long as you research the differences and understand how the new size will effect the coach. To help use a tire size calculator to see the differences such as - https://tiresize.com/calculator/. Going with a 275/70 tire is a 1.1% gain (.4 inches) in diameter but 16.1% (1 1/2") in width which could rub on the suspension/framing during tight turns or the space between the rear duels and potential contact between the tires.

Regard brands other than the bigs (Michelin, Goodyear, Bridgestone,,,), I've had good results for the secondary manufactures which are actually subs of the bigs and save a lot on the cost. Last set on the coach were Kelly (sub or Goodyear) and now I have Uniroyal (sub of Michelin). The Kelly tires held up very well for 9 years and I was able to sell the 6 for quite a bit on Craig's List. I'm a little hesitant with the more distance producers.

I would NOT consider a 275/70.

In addition to being much wider (potential interference with suspension or body) very likely your wheel designed for the 235/80 would be too small/narrow for the 275.

Agree with others that a 245/75 IS a reasonable alternative.

Stick with the correct size listed by the MFG of the MH.
I would avoid all Chinese Tires they are not worth risking your life on.
If they are selling NEW tires for less then 300.00 each run in the other direction they are guaranteed to be junk.

If you like Michelin go with them and find another area to save money.

NEVER go cheap on tires and or Maint. items it will cost you more in the long run.

The 245/75/22.5 size is a popular replacement for the overpriced Michelin 235/80/22.5. There are several good brands that will perform the same as michelin at a substantial cost savings. Don't fall for the "Michelin is better" line that some believe.

Agree, 100%.

After. 3 year old Michelin blew out I switched to Toyos and have been very happy. My last Michelin rode rough and Michelin offered no assistance.

Also agree!

If there are 'bombs' out there then it should be easy to find lots of 'smoking guns'.

I went with Yokohama 255/70R22.5 RY023 16 ply. The main reason was the new to me MH had 10 year old ones that looked to be in very good condition and had a nice ride.

Also they were made in the USA. Since the OP is Canadian may not be important.

When tire replacement became a concern, I walked around trucks stops noting tire brands on steer axles. One tire stood out, Sailun truck tires, when I began an internet search I found they are quite popular in Canada, and were becoming known in the states.
They are constructed the same as Michelin and Goodyear- all steel belt construction. The manufacturer moved production from China to Vietnam to improve quality and eliminate some taxes being imposed.
I had 6 275/70R22.5, LR H, installed on our MH in 2017 for a final bill of $1,280 including all taxes. IMO they ride the same as the Goodyears they replaced, and seem to have better traction/road holding ability.
