Bill, I just replaced all eight of my 295/80R/22.5 through the Michelin FMCA program as my old Michelin date codes ran from 2006-4206. I was invoiced separately from Michelin for new 295/80R/22.5 XZA-2 Energy tires. The dealer charged me for mounting, balancing and new stems. The dealer gave me $50 per tire trade-in ($400), so my bill from them was $192.
The invoice from Michelin totaled ($5,884.45) which is $735.57 per tire including all taxes.
Complete total= $6,076.45
PS.. The only way to tell if your tires are really in good shape is to have them removed from the rims and inspected on the inside. Apparently, mine were fine as the tire guy said my tires were in excellent shape with 57,700 miles. I was, and will be, religious on checking air pressure and taking the best care by not curbing the new tires, etc.
