Big difference in a tire that has never been mounted than one that has and has been exposed to the elements Don It is all in the compound of a tire the tubeless tires of today are mostly a synthetic compound as the old tube type were mostly rubber
Our oldest is a engineer at Michelin in Ardmore he couldn't even get me a deal lol he was Dayton for years in OKC till Bridgestone closed that plant there I got deals good luck
Well i have a set of Firestones on the Eagle that the code say that they are 10 years old and they look like the just were put on. I plan on running them until they POP lol but that's me They never see the light of day unless they are turning round and round and when parked they always have something under them.
Back to our original subject, the seller of the tires referenced by the OP has stated that they are dated 2003.Maybe not such a good deal after all.Bob
See I'm not the only one
