fried,
Any more info or pictures of what you have? I am in the hunt for a new set of tires and rims for my 1920 and mine has the oddball big tire option with the 14.9x24 rears as well. They would have to be shipped to me as well though so not sure if your interested in that headache or not.
Query, you say oddball big tires....do you have the agricultural tires with bar tread which would be 14.9 x 24?
Or do you have the turf tires, like smaller lawn mowers have? They would be on 16.1 rims and quite wide looking like big lawn mower tires.
What about the fronts?
If 4wd, you have to keep ratio between front and back the same .
I am looking for Bar tires. Old style tractor tires.
Thanks
Mark
