I have turf tires on my B2620. Most of the time they are perfect for my uses. The only time I wish the tires were agriculture tires is when I'm using ground engagement equipment (eg plow etc.) I am considering getting a full set of tires and rims that I can put on my B2620 when I need them. Does anyone know a good source for these besides the Kubota dealership? I'm hoping an aftermarket source will be cheaper. Does anyone have any idea what a full set of tires with rims would cost?
