I got these tires today for my Kubota L2000, I've been running turf tires for a couple years now because it was all I had. Finally broke down yesterday and ordered these 8.3 X 22" tires off of eBay. The seller was in MO so the tires were here the day after I ordered.
These are the deep rice and cane tread tires. I wanted something aggressive since this tractor is only 2 wheel drive. I believe these tires should serve me well. The tread is aprox 2" deep in the center and then gets aprox 4" deep on the sides. Can't wait to test it out with the rototiller.
