I ran across a set of Goodyear 23 x 10.50 x 12 AG tires in pretty nice shape on Craigslist mounted on some JD rims from a John Deere model 240. The 5 holes seem to be correctly spaced, but it seems to me that according to all the pictures I have seen on this website that the valve stem is on the opposite side of the rim itself. I haven't taken the wheels and tires off my 1512 yet, but it also seems like the offset of the center (I hope I am using the correct term) seems to be more in the center on the JD rims, than it appears on the various Cub Cadet rims I have seen. I have attached a few photos. The tires are mounted correctly on them as far as tread direction. I'd really like to have 2 sets of tires, the turf tires on one set of rims, and the Ag tires on the other. I was thinking about making that same upgrade that Rob Neubauer showed in his May 29th post changing over to studs instead of bolts to mount the tires. Am I wrong or seeing something incorrectly? The 2 tires on the rims only set me back $50, so I am pretty sure I can sell the rims to some JD user for that much. I just need some guidance before I start taking the chains, wheel weights, and rims off my tractor. Thank for all your help. SteveG.
