Actually it was a surprise to me. I don't know much about RV tires but do know more about motorcycle tires and would not have accepted a tire in that condition on my motorcycle. Investigations by the Feds are one thing, actually doing a recall or issuing any sort of warning is another as it takes time and data. Michelin does make a lot of tires for about everything and generally they are a quality tire though a bit pricey IMHO.

Glad you caught this!! But even a 6 month old tire, from any manufacturer, could reflect damage like this - if it had been abused and grossly under inflated.

Best,
Smitty

Good point Smitty !
I don't see a lot of Mh's traveling with low tires but I do see Travel Trailers all of the time with low Tires- wondering what they are thinking.

Very excited... getting my new tires tomorrow !!

I'm hoping there was a bad run back in 2611 when these tires were made.. I'd like to think I won't be having cracking issues with these new ones... fingers crossed !!

Total and absolute waste of money. It will make zero difference in safety and convenience.

I've been using N2 for 16 yrs in my tires - all of my tires - MH - Cars and my Dixie Chopper . Pressures stabilize and never increase more than a few lbs. Hot Or Cold .
The ride - no different than with Air!
Major difference - No Moisture in my Tires which when heated causes higher pressures !

After my 2nd set of Mich's ($2700)I went with the cheapest I could find. Some Ohtsu tires. yeah, an unknown brand that is used on semi trailers. I have 19.5's and they they cost me about $1400 for 6 mounted and balanced. Now that is cheap......

I expected them to last 3 to 5 years like the Mich's

7 years later they are still in perfect condition with no cracks, I haven't noticed and performance issues while driving, but I don't drive my moho like I drive my Eldo!

That said, when first starting out in the mornings, I have to put a lid on my coffee cup because of the flat spots that take 5 miles or so to warm up and disappear. But every old horse takes a while to work out it's joints in the morning....

Totally and absolutely agree.

Maybe N2 us useful in a tire for a F1 race car, but not for anything driven on roads by mere mortals. It's just one more way to separate folks from their money.

I believe that in the grand scheme of things, there is a very small number of cracking issues with regards to the michelins. I had one set on my previous motorhome and ran them for 90000 miles without a hiccup. I was pleased to see michelin on my new coach when I bought it. I pay very close attention to my tires. I weigh the coach, obey the michelin tire chart and run a tpms system. I would argue that the majority of cracking issues are due to high ozone levels that may exist and not just from exposure to the sun. I also believe that lack of use contributes greatly to the cracking. Our year around use of our coach most definitely helps distribute the lubrication properties that are built into the tire compound. I'm super happy with the way my XRV's ride and will definitely continue to run Michelin. I think it says a whole lot about a company that will step up and pay 90% of the cost of replacement tires after 20000 miles. Unfortunately the internet is a sounding board for unhappy consumers. You rarely hear from the 99% who are happy consumers of whatever product that is in question. This thread seems to prove this out when you look at 11 pages of comments and in those 11 pages you have Mel comment 10 times about never purchasing another set. (sorry mel not picking on you, just demonstrating a point) My point being that the unhappy ones are much more vocal than the happy ones. The thread went from minor cracking to one poster claiming the tires were possibly life threatening which definitely hasn't remotely been proved. After 90k on my first set and 20k on my current set, not to mention the great ride, I feel very comfortable stating that I believe the XRV to be a great choice among motorhome tires. OOPS! SORRY MEL IT WAS 14 POSTS! LOL

Something that no one has mentioned is that what causes the cracking? I think it is a combination of dry rot, caused by extremely dry air, UV exposure and poor chemical engineering. Most of the time when the cracks occur the tire starts to delaminate which causes a slow leak through the layers of cording. I have seen massive damage done by blowouts, totally destroying rear wheel wells and removing side panels with rubber parts inside the coach. I've noticed that the Arizona climate seems to cause more dry rot sooner than Cali coastal climates. Some tire brands last no more than 5 years in these dry climates. I think what folks are complaining about is that they pay for big $$ for a quality product and then it only lasts for a few years.


My father, an old cowboy, was one of those guys who didn't like to replace a tire until he could see the cording and would often wait until it was flat before replacing it. I asked him about it one time, he said "that living in the city it was unnecessary for new tires, you could buy one anywhere." Said "wait until you have to change a tire on a dirt road in the rain, doing it on the pavement is easy!" in the past 36 years I've had to change one moho tire on my 3rd rig in the middle of the texas desert where there was no cell phone reception. Took me 2 hours in 110 degree heat, an inside dual with brand new tires. No fun at all!!!!! Since then I check in between the tread for cracks every 5k when I change the oil.

I agree that sidewall cracks are not a problem with the vast majority of Michelin tires.....and that mine may have cracked badly enough in 42 months that even Michelin agreed they were unsafe to use because of lack of use.....mine had only been used for 11,000 miles in that 3-1/2 years, (approximately 2,000 to 4,000 miles per year).

I apologize for expecting Michelin tires to last longer than 42 months.... and for posting my personal disappointing, (aka: PITA), experience with Michelin tires, (and Michelin sidewall cracks), 14+ times on this and other RV forums.

Apparently my Michelin sidewall cracks were my fault ...(not a Michelin defect)??

BTW the 2 previous sets of Goodyear G159 tires on my coach each lasted 7+ years...over 60,000 miles...(7,000 to 10,000 miles per year).
