Tireman, I am ready to replace me 275/70 22.5's and have narrowed the choice to XZE2 or XZA2 Energy. Can't get Michelin to recommend one over the other for RV application, which I found interesting. I believe the XZE2's will come in about $40 less per tire than the Energys. That will be $240.00 total + tax, so it will take a bit of driving to recover any fuel savings the Energy's might offer. The both have the same load range rating, so no advantage there. My coach is a '99 Beaver which came "overloaded" straight from the factory. Not sure how they decided the GAWR, but hopefully it was based on tires available at that time, rather than actual axle capacity.
In any case, my leaning is towards the XZE2's as other BAC members have reported complete satisfaction so far.
On other question, regarding balancing. I've heard many discussions about front only, all tires, spin balance on the axle, Equal and now bags of "glass bead" silicone balancing. No one here seems to do lead weight balancing. What do you think?
Thanks in advance,
Jim
