A few weeks ago one of my co-workers replaced all 4 tires on a Kubota ZTR the summer help guy uses for mowing around the plant we work at. This morning I noticed there were GT type tires in the scrap tire pile. I never figured that ZTR would use a tire that would work on any of my GT's though. I had to check as they would be going to the dump soon. Rears were junk but even though the profile looked too small, the fronts are the same size as the MF1450 uses on the rear! They have a lot of tread yet and not all weather cracked up like the tires I have! Had to grab them before they went to the dump!
