The tires I bought were the Goodyear Eagles and the codes are the same at my local Goodyear store. Maybe Michelins are different. Of course, I am not stupid as I have dealt with Sam's and Costco for better than 20 yrs and I always checked my tires(usually Michelin or Yokohama) after being there. If you look carefully you will notice their prices on the "good" grade tires aren't much cheaper. They had 4 and Goodyear had 3 that particular day. It had Dunslops on there and were noisy as hell. The reason I posted was just to remind people in a hurry ro double check every shop. And to follow MB recommendation to re-torque to 80# after 500 miles.
