I spent a great deal of time trying to find the 255x80r22.5 tires for my Meridian. I finally contacted Michelin and they recommended that I use the XZE instead of the XRV. After comparing SPECs, I found a SNIDER FLEET Solutions Dealer near me who was able to get me a set full set of DOT 2714 (July 2014) XZE's installed today. The deal through FMCA Advantage, and the friendly helpful service from the SNIDER service shop are truly exceptional.
I just drove home on the new tires, and I feel like a kid with a brand new pair of sneakers. Heading outside to treat my new tires with water based 303 Aerospace Protectant.
As a follow up to my previous comments. Since RV tires are subject to aging issues, it's a good idea to plan ahead and schedule your replacement before you have a failure. Dealers want to be able to supply the newest tires possible for our RV's which means we we need to order them and give them enough lead time possibly weeks or even a couple of months to get them ordered. I learned this the hard way almost my 8 year old tires had started to show some cracking.. Up till then I had never heard of the 5-7 year from DOT date rule.
