It's the chemicals Michelin puts in the RV line of tires to help them handle the low mileage and exterior parking.

I have recently replaced the Michelin tires on my '03 DSDP. The size tire that I have is 275/70R22.5. I got as many answers as tire dealers about the type of Michelin tire to replace the tires that were on the coach and no longer available in that type and size.

The web site for Michelin is not as good as talking to the factory rep in SC at 1-800-847-3435 or 1-888-552-1213. They also sent me a book, "Michelin RV Tires", that lists all of the RV tires available, a short blurb on each type tire, the sizes available along with other helpful info on the care and feeding of RV tires.

I ended up choosing the XZA2 Energy tires, the only ones listed in that size.

Michelin is offering a rebate of $15 per tire on the XRV tire through the end of May. It is not offered in the above size and load range.

Haven't looked at Michelin site in some time. They now have a X ONE XRV tire to replace duel tires in special applications. Never saw so many X's as on the site now.

Hi Ed,
You made a good choice with the XZA2s. I've had them on my steer axle for 3 years and they are great tires. Very smooth riding. They show almost no wear after 40K+ miles.

For what it's worth, a few years ago (02-05) when people were having trouble with blowouts, the only ones that blew out were the xrv tires.

The explaination given at that time was the xrv tire had a more flexible sidewall giving a softer ride making it more attractive to the RV community.

The greater flex caused a greater heat buildup leading to blowouts.

On my '01 DSDP I had XZEs and got over 90,000 miles with plenty of tread left, replaced with XZA3s. Great ride on these steer wheel tires. Never had a bad ride that wasn't related the poor quality road surface.

Look further at your tire. The is an X series of Michelin tires but they have more to the the name like XRV, XZE, etc. I find no tire the is just X.

I am in the process of replacing my tires with the XZA3 also. I am presently running the XZA2s and have been very pleased with them. I have weighed the axles individually and found that I did not have to run at full pressure -- my fronts at 100 PSI and my duals on the rear at 95 PSI. The ride is very comfortable.

O.K....tires read as follows: 315/80 R 22.5 MICHELIN X, PILOTE XZA 1, Radial Regroovable. max load single ..... 19090 lbs. max load dual ..... 18270. I also run 100 psi front, and 95 rear duals and tags.

So, DavidK, what's the difference between the "X 1" and your "X 2's, or new X 3's"?? Steve

I will try to give an explain on the differences if I can.
The XZA 1 is an all position tire. It is a load range L which gives it the high carrying weight capacity. According to Michelin inflation guidelines, a single at 130 PSI will carry 9,090 lbs and a dual at 130 PSI will carry 1,640 lbs. The 130 PSI is the max rating for the sidewalls. This tire is rated for long hauls.
The XZA 2 is an all position tire. It is also a load range L tire which gives it a high load carrying capacity. According to Michelin inflation guidelines, a single at 130 PSI (again the max) will carry 9,090 and a dual at 130 PSI will carry 1,640. This tire is rated for long hauls and is a low profile tire that is "suppost" to give better fuel mileage.
The XZA 3 is an all position tire that is suppost to give better wear and mileage -- it is the latest version of their all position tire. It does not come in your size (the one you listed in your posting). It has an enhanced shoulder to improve the wear at that point. It also carries a 7 year / 700,000 casing warranty. In my size 275 / 80 / R22.5, load range H, at the max air pressure of 120 PSI, it will carry 7,160 for a single and 13,220 for a dual set up.
There is a lot of information up at Michelin's web site -- www.michelin.com and then select RV tires.
