I've had excellent service out of my Michelin tires. I just replaced all eight with a new set using the FMCA Michelin program. My original tires had date codes from 2006-4306 so they were about 7.5 yrs. old. I had 57,700 miles on them when I bought the new ones. The Tire center gave me $50 each for the take-off's. Total bill including installation, new stems and balance was about $6,100, (295/80R/22.5) XZA2 Energy.
I had such good luck with the first set that I decided to go with the same brand. I have now put almost 3,000 miles on the new set and everything is going fine.
