I have both new and used. The used ones are on rims that fit 2000 and older combines. they are 10 ply goodyear. They ran about 200 hrs. The new ones are 10ply Firestone on the same 8 hole 2000 and older combine rims (AH205187) I also have 28lx 26 Radial Goodyear on 2001 and newer rims. I'll sell any of them for $750 a pair rims included.
