I replaced some of the same size with 600/50R22.5 tires. 560/60R22.5 would be closer in width. You only gain a couple inches though. Just an option if you want similar flotation at a better price.Have 9 bolt pattern rims on our 2940 Macdon swather. Trying to get a little more room for a 30' canola swath. Have 21.5 X 16.1 tires.
Anybody found anything else that will work.
