The date codes turned out to be 0907. I was very angry and got the store manager involved but I was stuck. They extended the warranty, which is pretty meaningless. They swore up and down that the tires had just come from the Michelin warehouse. I don't know if I believe them or not.

Moral, don't let them take the tires off until you inspect the new tires.

bruceh, The Michelin warranty begins from the date you purchase the tires, not the production date. The only time production date is used for warranty purposes is when you cannot prove date of purchase. I just purchased 2 XZE Michelins for the front or my motorhome with a production date of 2008 from Costco. My old tires were XRV's and were badly cracked on the sidewalls.
The warranty information is in your warranty booklet, and also on Michelins web.

Just as a matter of trivia ... IF you never put air in the tires, they actually do not even begin to wear.

If you have a Michelin tire that is a few months of DOT date code out from another it won't matter at all. As soon as you air up all the tires that is actually when the clock starts ticking "wear wise" . Warranty begins on the date of purchase and is cross checked using the DOT date code.

I wouldn't fuss too much over a few weeks if it came to that.

Now when I ordered my tires, even before I showed up at the dealer, I insisted that they all be the same date code.

Now I could have gotten newer tires but they were short by 1 tire so I had to settle for tires that were a few weeks older - but they all match.

Michelin tells us that we can go 10 years before we have to change our tires - that's a long time in the RV business or ownership. The tires are warrantied for 5 years.

A Michelin Tire and Rubber representative will be at the WCMC Rally in Myrtle Beach this October.

We appreciate their support!

Maybe I am in the weeds here and someone can correct me.

I have thought that there were two factors in the life of a MH tire, wear as in the tread is worn out and age as in sidewall cracking.

I never expect to wear out a MH tire. My old tires (original XRV) had moderate sidewall cracking and date codes from 2000.

The new tires are already a year and a half old, 0907 is week 9 of 2007 unless I don't understand date codes. This is more than a few weeks. Granted that they have not been stored in the sun but isn't the age clock running from when the tires come out of the mold?

bruceh, you are correct as to when wear begins, sidewall cracks seems to begin only when the tires are subject to sunlight. Michelin calls it "sidewall checking and cracking due to exposure to ozone." I just replaced the front XRV's that were just 5 years old because of deep sidewall cracks. (1/8 to 3/16 inch deep in places. Started cracking after about 2 years of use. Cracking not covered by warranty, didn't trust them so replaced. Inside rear duals are NOT cracked either side, because of no sunshine on them I suppose. Rotated them inside to outside, and hope to get a couple more years out of them. I live a few hundred miles south of you, east of Bakersfield.

I believe it is, but the aging effects are obviously not as severe as a tire in service.

Just recently, I returned from a trip to the Pacific Northwest. Upon returning home, I had a softball sized bubble on the side wall of my L front tire. I limped it down to my local tire shop (whom I really like), and switched out my Michelin XRV spare for the bad one. I have since put a use Goodyear on the spare. All pressures are checked religiously and the date code was '02. Moral of the story is to check your tires every trip. The tire experts have really no idea why this happened. somemetimes things just happen.

I believe you will find that Michelin XZE tires are NOT recommended for motorhomes and are recommended for local driving only such as delivery. You might check with Michelin on this.

dieselclacker · 08-12-2008, 01:25 PM

Thanks for your concern. I did check the specs for the XZE's and they are speed rated to 75 mph and load range F. My motorhome is equipped with 19.5 inch. Side wall is just a tad stiffer than XRV that I replaced. They are on and seem to be just fine for the short time I have had them.
