I'm now unhappy with Michelin XZE2+

I put them on my steer axle last year and really liked the ride. I was very happy...until now.

Aside from trips, in the past year the coach was stored indoors from last May (when I put them on) until this February when we brought the coach to Cheyenne to stay in until we found a house here. So the last 90 days the coach has been outside and exposed to the sun.

Both the XZE's now have sidewall cracking all the way around them. Nothing huge and ugly, but not something I would expect from a year old tire. Something I'd expect from a 6 or 7 year old tire.

My drive axle has 2007 Goodyears, I know they've spent a lot of time in the sun (including obviously, the last 90 days in the same conditions as the Michelins) -- and not a sidewall crack to be found.

I know the XZE's aren't RV tires, but neither are my Goodyears (I think they are G149RSA's another Regional-spec tire).

Color me VERY disappointed at this time. I haven't decided to change out the Michelin's... but when I do, it'll be for something else, that's for sure.

Steve

What is the "born" date on the sidewall? Some dealers have been known to sell 5 year old tires as new.

Another question is: have you ever used a tire dressing or protectant on them? Some of them can prematurely age a tire and cause the cracking.

From Michelin:
Quote:
"If the cracks are less than 1/32" deep the tire is fine to run. Between 1/32" and 2/32" the tire is suspect and should be examined by your Michelin dealer. If the cracks are any deeper than 2/32" (1/16") the tire should be replaced immediately"
I'd take them to a Michelin dealer along with the receipt and see what they will do for you.

When I got my previous coach it had original Michelin RV tires on it. It was two years old when I got it and all 6 tires had small cracks in them. I drove on them for two years and they never got any worse but I couldn't stand seeing the cracks so replaced them.

The date code was from late 2011. The cracks are very very small and fine so I don't believe they are an issue. It's not like you can stick a fingernail in them or anything... but again, the old Goodyears don't have any of this, and I know the coach sat outside for at least 4 months before we bought it, so even if it had somehow been covered the entire rest of the time since the drive tires were mounted, they have seen twice as much sun.

If the timing works out we'll hit the original selling dealer in Rock Springs in a couple of weeks and see if they can do anything, but I doubt it.

That is a reason I will no longer run Michelins on any coach we own. I have Coopers on my farm truck and they are over 10 years old - no cracks. I run it a couple of times per month and it is stored in a shed.

Michelins are notorious for the tiny weather checking. I hear folks screaming about riverwear on Goodyear G670's, but nary a word about the endemic sidewall cracking on Michelins. Michelin must have a better PR company!

Our 2007 Bounder had Michelin XRVs on it from the factory - it was built in October 2006 and the tires had a date code of 3506 - at least 5 of them did. The 6th one was a 3405 date code for some reason. A couple of months ago, during a pre-trip inspection I noticed that that 6th tire had significant cracking around all the lettering on the sidewall - the other 5 tires had absolutely no cracking at all. I went ahead a replaced all 6 tires, with Michelin XZEs, and would not hesitate to stay with Michelins again.

I don't know why my Michelins would give me 6+ years of service - when we're not using the RV it sits outside with no tire covers - we put about 4K miles per year on it so it's definitely NOT wearing out the tires. Maybe we're just lucky...

We have Good Years GY 670 and the (04/07 date code) and I was considering Michelin when we replace them. Most of the Prevost are shod with Michelin and I always considered them to be the best tire manufacture. Reading about all the zipper failures and our less than stellar performance with Michelin on one of our cars makes me wonder if they are living on their past reputation? We use Good Year on our cars and they have been very good.

My G670RV's are due to be replaced based on their age, but they still look excellent; no sidewall cracking, and I have never had a problem with the "rivering". They ride and handle very good. Before I bought them, I spoke with the Goodyear factory technical rep, who told me, among other details, that Goodyear puts UV stabilizers in all the rubber of the entire tire, where other manufacturers do not. I have no idea why so many Michelin's crack, but I have heard about it from many owners.

When I do replace the 670's, if it is not with another set of them (and it probably will be), I will most likely go with Toyo's.

Hankook used to make their AH11 in 275/70R22.5 but it looks like they no longer do. Now I am regretting not having gone with them....

The local Goodyear shop will put 670's on the steer axle for $1,000 all in, which seems pretty decent, but like I said, I don't think they Michelin's are a safety hazard right now (although I doubt they will make it many years at this rate)

I have to wonder why Michelin passenger and LT tires do not premature crack. Seems if they can do it for some...they could do it for all. The big tire certain has no idea it's on an RV so decides to crack on it's own.

I have always been a Michelin fan and do have them on 2 vehicles now...1 vehicle garage kept but 12 yrs old...no cracks

I have had to replace my Michelin LTX tires on my 2003 Chevrolet 2500HD due to sidewall cracking. Local Michelin rep tells me he sees it everyday on cars and trucks parked outside running Michelin tires, where the owners are not running tread down fast.

Different rubber compounds - tires made for cars and light trucks have chemicals in the rubber that inhibit oxidation. As the tire rolls down the road those chemicals are constantly moved around in the rubber, being brought up to the surface to protect them. Large truck tires may or may not have th same compounds - but when the tire sits for most of its life the anti-oxidation compounds do not get moved out to the surface of the rubber, therefore it can't protect the rubber from oxidation. If you put 15K or more miles per year on your motorhome you'll probably wear out the tires before they die of old age, if you only drive a few thousand miles per year in your car, then its tires will probably die of old age with a ton of tread left...
