Experience Switching from Michelin XRV to XZE

I should have mentioned that my 5 year old Michelin's are showing some signs of age with minor cracking and checking. I am going to replace the steer tires with new ones and move the steer to the tag axle where the tires wear out about twice as fast as the other positions. I should be good for another 5 years with Michelin despite the made up 7 year rule.
