^Only problem...can't rotate the tires to all four corners.....just left to right. AND...that's if the tires are NOT directional. If you want to rotate the directional tires from left to right, you have to remove them from the rim and get them rebalanced.
No thanks on 20's and 21's from me. That would be mighty expesive having to replace the tires.....and a little more often for me...
