My W22 has 25,000 miles. Today I measured the tread depths on front tires. Right shows 13/32 on both inside & outside groves. Left front shows 11/32 on outside and 13/32 on inside. Would anyone have some incite on the cause? My guess would be camber but the manual says caster & camber are not adjustable. Would tow-in cause just the left outside to wear? Is this normal or excessive? Your thoughts will be appreciated.

Thanks;
Don

Excessive; maybe not, normal; probably yes given the number of miles you show. If it's been awhile, it maybe just about time that you visited the FEA shop.

If you show too much wear sometimes they'll take the rear tires and put them on the front axle and then do the FEA.

The caster and camber can be adjusted but the axle has to be bent. I'll guess this isn't your problem and your toe-in is out a little.

You should be able to measure the tow-in with a tape measure. Measure the distance between the back of the tires, then the front distance. There is a link to the procdure on iRV2 somewhere in someones post.

If I were you I'd take it for an alignment check. I'll use my local school bus/computer alignment garage for alignments if every needed.

I just purchased a 2002 Holiday Rambler Vactioner with 17,000 miles. In doing some internet searching I found that many people are concerned about the 235/80 22.5 Michelin XRV tires. Thus I am considering to change my fronts; I have the option of:

Michelin XZe
Goodyear
Bridgestone.

Please send me comments. I am looking for as much safety as possible.

Thanks, HEMI

So what is really wrong with the XRV, I've been using them for thousands of miles. Try this, count the amount of people complaining about the tire and then put that number up against the amount of tires out there that have no problems. then check with the various other tire manufactures to see what there problem numbers are. I don't have the facts, but I bet they are all pretty much the same. Personally, mine work, so I'll just keep getting what works.

I have the same set of Michelin XRV tires 235/80-22.5. My tires are dated 3202. I have currently accumulated 50,276.5 miles and the only problem I had was a slow leak when I picked up a nail.

Since I will feel more comfortable changing my tires later this year after of 5 years of service I can only say that I hope that my "next" set of Michelin XRV tires serve me as well as my original set. I am estimating that my tires will have 57,500+ miles on them by the time they get replaced no doubt sometime around 3207.

At this point in time the tread shows no appreciable wear aside from the shoulders on the front tires which exhibits a normal wear pattern.

Remember Workhorse isn't installing Michelins on their chassis because they are a low bid tire. The new "First of Its Kind" UFO chassis uses Michelin 255/80R22.5 LRG XRV tires.

Driver and Yosemite,

good recommendations....since I have to buy a spare tire just to have it along in case I am in the boonies and one of the current tires shreads or something, I will purchase one new Michelin xze now. Although pricy, it comes highly recommended. Then in a month or so I will get another xze and then have the front tires changed out with new xzes, leaving the xrvs as good spares...they only have 17K on them.

I've always liked Michelin...all our other cars and pickups run with Michelin.

Thanks for the recommendation.

By the way it was only yesterday that I heard some negative news about the XRV. The best tire store in our town (Melbourne FL) told me about problems with the XRV and also recommended the xze. Then I called another truck/RV tire store in a nearby town, he said the same thing and recommended the xze. After hearing from these two sources, I did some internet searches to discover that some (but not all like you) people have experienced problems with the XRV.

Anyway for peace of mind I will go for the xze.

Thanks again

What exactly are the complaints concerning the 235/80 22.5 Michelin XRV tires???

I also have Michelins with 22000 miles on them. No problems at all except for a leaky valve. I think the trick is to maintain proper pressure and proper loading...

Have you had any problem with sidewall cracks? I have a 2004 Allegro, with 14000 miles, and am expieriencing cracks around writing on sidewalls of my Michelins. Tires are wearing real well.
I live in California, maybe weather related possibly.

YosemiteBobR · 11-02-2006, 12:33 PM

Do you keep them covered when not in use?? I have the same tires and have 42,000 and still they look good. I also live in So Ca.

Hemi · 11-02-2006, 02:39 PM

Yes, I can see small cracks concentrated in an area in the sidewall near the writing close to the steel wheel. This occurs on the right front but the left front looks perfect. On the rears, the left rear (outside, can't see the inside) has about three small cracks.

I don't know the history of the RV...but from the condition of the gelcoat I believe it has been stored outside (in Florida). Over the summer I had a large RV/Car garage built and thus when the RV is not in use it will be stored inside.

The tires are Michelin XRV.
When I picked up the RV a few weeks ago the air pressure was 90; my tire dealer told me that I should be running at 100 PSI and thus I added more air.

The RV has 17010 miles.

Two different truck/RV tires shops told me that they have experienced problems with the XRV and advised me to buy either another brand (Goodyear or Bridgestone) or if I decide to remain with Michelin replace the front XRVs with Michelin XZE which I am doing.

One tire shop told me apply a uv protection fluid to the tires..
