Since new I've routinely cleaned my Michelin XZA tires and periodically applied various protectant products including 303. The tires have never been covered. The rig seldom is stationary for more than a few weeks as we routinely move several hundred miles at least once every month.

Anyway, after about 5 years my tires began to develop minor cracks and now at 7 years they have some significant cracks that per Michelin's guidance require replacement. Six new tires will be installed in 3 days! Bad news is the huge cost on a fixed retirement income

Anyway my rig has spent a lot of time in the southwest (San Diego, Las Vegas, Arizona, etc) where the temps tend to be much higher and the sun is much stronger than other parts of the country. So I tend to agree with Dieselclacker as the location (temps and amount of sunshine or UV) seems to have a significant impact on the development of cracks.

It was interesting that while shopping for new tires more than one dealer strongly suggested looking for an alternatvie to the Michelins as in their opinion the Michelins seemed to crack much worse than any other brand. Given I drive only about 15K miles per year, I most likely will never wear out the tires before cracks develop, regardless of brand.

Anyway I've elected to go with Yokohamo RY023 tires. The RY023's are proven tires and more than meet my size and weight requirements. Hopefully future cracks will be minimal.

Roadking, I thought Yokohama tires were as good as any. What size are yours, where did you get what price. Have been looking at on-line sites for price and can't find my size, 235/80r22.5. Will probably have to stay with Michelin if warranty covers at least as much as others with many more miles than my -6800.
Also you might want to look into this before you go with Yokohama,
Anyone know what the max size replacement would be for my rig?
BTW the local Michelin dealer quoted $495 per tire w/$18 per for balance plus tax, not considering warranty. The Yokohama on-line prices for 255 tires looks really good.

Current tires are Michelin 295-80 R 22.5 load range H. The Yoko's I've selected are 11R22.5 load range H. The specs on these are almost the same as the 295/80's with the diameter being just 1/10 inch smaller. This results in 504 revs per mile vice 501 revs on the Michilens. Thread width and max width are the same. The biggest diff is the weight capacity. In dual the Yokos have about 500lbs less which is ok for me. I've delayed replacement to long and the only ones I've found are at a local Purcells truck tire store at $360 each plus FET plus sales tax. Also $22 to balance. Mounting is included in price. I'm a little concerned about any waranttee issues as the Purcell stores are few and far between.

Three months ago I saw these same tires in a Pilot store in Las Cruces NM for $299 ea. on a special. I wish I would have bought them!!!

In regards to your tire size it will depend on your rim size and rim capacity. I can only suggest doing some research and per chance call the manufacturor.
I'm aware of the Yoko's and several other brands having recall a few years ago, maybe 2005, due to using a rubber compound from a supplier that did not meet appropriate specs. I'm assuming this problem was resolved a long time ago.

I just had 6 Michelins 235/80r22.5s put on my Aerbus for a total of $2721.00 by a mobile service. I think it was $379 per tire + mount, balance, and service call. $495 seems way out of line. There is a tire dealer on ebay selling them for $299 each.
