I recently bought a 4 ft king cutter bush hog from an estate sell. Someone put a pneumatic tire on it that measures 16 inches tall. This makes it nearly impossible to use because of the angle that is caused by the large tire. A friend has a 4ft hog of a different brand and the wheel on it measures 12 inches tall. I have not had any luck fining a 12 inch solid tire for a rotary mower any place online. Does anyone have any thoughts on where I might buy one?
