tire mfg size comparison charts

Clifftall · 11-30-2010, 04:37 AM

I hear all this talk about switching from one mfg to another but I cannot find out how to compare the size of my Michelins to the others : Toyo, Cont.,Goodyear etc. I have 235 80 xrv 22.5. Is there a chart?

The tire store should have a chart for there brand to what you have on you coach. I would stay with Michelins, have had them on 4 class A coaches and never had a blow out or other problems. Just bought a spare 235/80 22.5 XRV at Sam's club. Out the door $342.00, they don't mount you need to find truck tire repair shop.

You can access the Michelin RV Tire Guide by clicking HERE. I'm not as familiar with other manufacturers, but I'm sure the info is available on their web sites.

You have to look at the specs for each tire, usually available on the tire manufacturers web site, and compare the details yourself. Or rely on the tire dealer to do it. However, if you stick with the exact same size and Load Range, you should not have any issues because the differences will be extremely small, if any. The problems can arise when you try to substitute a different width (the 235 number) or profile (the 80 number) for the 235/80 you now have. Stick with 235/80R22.5 and you should be golden, no matter what brand you choose.

From what I've seen, other mfg. don't make a 235/80R 22.5, that's why I was wondering if there was a chart to assist with matching up this size as I agree with you that I want to keep the exact same size.

Thanks to all who responded

245/75x22.5 is a suitable replacement. You will find that size in Yokohama, Bridgestone, Toyo, Kuhmo, and others (even Goodyear if you are a masochist). The key dimensions are diameter and radius, width, and recommended wheel width and dual spacing. The load capacities are the same for the same load range. I also believe only Michelin makes the 235/80x22.5 size.

Even with Michelin the 235/80 in a XRV or XZE are not exactly the same size.

Goodyear gives equivalent sizes for some popular RV tires. See

How's that work? With the same section width and aspect ratio, how can they not be the same size?

It appears the 245/75R22.5 is the solution. I probably will stay with Michelin when the time comes to buy new ones. I just wanted to know my options.
Thanks
