Replacing tires on National Tradewinds

In need of new tires. Currently have Michelin xrv 235/85 R22.5. Would like Toyo but can't find in same size. Concerns are: different od and width for rear duals possibly rubbing each other. My rig is 99 Tradewinds

Suspect you actually have Michelin 235/80R22.5.


If so, anyone else's 245/75R22.5 is a very close alternative.


Yes, check wheels for proper spacing, but 95% chance your wheels will accommodate the 245's.

Yep, like he said. My Dolphin came from the factory with those Michelins and it's been running the 245/75R22.5 ever since that first set aged out. Running Toyos right now, which I'm very happy with.

The 245/75R22.5 is the metric substitute for the 235/80R22.5.
Perfect fitment replacement.
Same single max load, same ply, same revolutions per mile (meaning speedometer setting will remain accurate), same overall height and same tread pattern.
Safe travels to you and your family

This will give more revolutions per mile than either the 235/80 or 245/75.


The 245/75 is closer to the OE dimensions (546 vs 541 revolutions per mile)


255/70 is 552 revolutions per mile.


Compare other dimensions as well as weight rating any time you are considering changing tire sizes.

Tufftj why Toyo if you don't mind me asking. The Michelin is a damn good tire. I keep my eye on the price and they are around $450 each which is not bad for the tire you are getting.

I think you'll find you're off by about $100 per tire. You might see a few web sites that lure you in with a low price only to make it up with high shipping costs. All things considered, I found Michelin to be about $200 per tire more than Toyo. Additionally, Michelin motorhome tires have a reputation for weather checking prematurely. Can't personally verify whether that's still the case, as the last set of Michelins I bought for a coach was 20 years ago, but mine did start cracking at around the five year mark.

Julia 2005,
This was my second set of Michelins. They are very costly and seem to provide a harsh ride. Toyos are said to run smoother. Quite a large price difference is what I'm seeing.
Thanks for your question.

CamJam1,
Mine are 9 years old and no cracking. They just wore badly in the front position. I think it's due to lowering the tire pressure to soften ride. 97 lbs. Ooorrr poor alignment. I've got about 50k on them without rotating.
