I did a search for blowouts...

... and what I noticed is almost all of the first bunch of posts all involved the same Michelin tire, the XRV or whatever it's called. hmmmmm

When I first bought my MH, it had Michelin 235/80R22.5 XRV tires. There were a number of reports of "zipper" failures, (sidewall blowout). As I remember, at some point Michelin revised the load and inflation pressures for the tires and raised the max inflation to 110lbs from 100. The failures were then blamed on running the tires underinflated... I don't know if any physical changes were made to the tires but the failure reports seemed to decrease.
The XRV tires on my MH had little margin for error and required near max pressure. I replaced them with Goodyear G670RV tires, in 275/70R22.5, one load range higher and they only require 85-90 psi to support the Mh weight with a good safety margin.

WOW...I was actually wondering about this after reading that post from earlier today. I have GY's on mine although I have been a fan of Michelin's for a long time.
Still, interesting findings as this is one of my biggest fears.....

Do you know what the max wheel pressure is on your rev.

Maybe it's because there are more of that particular tire being installed on RVs? Let's not go off half-cocked with unscientific data.

Ah Jeez, get a woman involved and all that they want to use is common sense!

This can be critical. Decades ago, I put Michelins on a single axle car trailer, and inflated the tires to the max. sidewall pressure. I came home from work one day to see the steel (Dexter) rim split around 3/4 of the circumference. I was actually able to speak to a human in the Dexter engineering dept. and learned "That rim is only rated to 70 PSI".

While this concerns a trailer rim, overinflating a motorhome rim could have the same consequences. I remember hearing somewhere these rims have the max. pressure stamped somewhere on the component.

I guess this brings up a general question of what is a "load range "? Is there an industry standard ... Or is this manufacturer dependent . Does any one out there know???

I bought that size Michelin xrv last year via the FMCA Michelin program. My third set of Michelin xrv's. Never a problem with them so I keep coming back.

This is a quote from a thread on this same page just this morning. Incidentally I'm on my third set as well. What does it prove? Nothing, except the two of us are happy with our tires.
