I would like to move the rear tires on my Turf Tiger out by about 1/4" to 3/8" to give it a wider stance. Is there a correct way to do this? Do they make spacers to put between the wheel and hub? It's no big deal but I would like the extra clearance. Why? Because I cut such steep area's that the tire can flex and rub the parking brake bolt after a long period of time. I could put more air in the tires but that would reduce traction.
