I have a pair of Goodyear 16.9 , 34, rears about 60% worn, they were holding air as tubeless when removed, only changed as I gave the tractor a present of a complete new set of boots after stuffing a big hole in a front, which were well worn. been off for a couple of yrs but might be useful for classic or paddock type of work. no idea what they are worth but open to offers, if totally stupid I'll keep against a rainy day.
