We replaced 6 Michelins 255/80R22.5 date code 2006 in June and we ordered them through Costco and were glad to get a date code of 2014. We took them to a tire dealer to dismount, balanced, and remounted the new ones. They wanted 10.00 per tire to dispose of them. We said "No Thanks" and brought them home. Listed them on Craigs List for $600.(one hundred each)and must have gotten 15 calls. We sold them for the listed price in just 2 days. They were going to use them as tag axle tires on his dump truck and was tickled to get them. So were we! We live in Chesterfield, Virginia.
