fender rolling 300 Fender RollingFender Rolling is the simplest way to accommodate larger WIDER wheels on your car. If you feel your inner fender right above the wheel, you will notice (in most cases) that there is an inch of sheet metal folded inward. That fold can be “rolled” upward to avoid that edge eating away at your nice tires. The paint is first heated so it will be soft enough to bend without cracking, and then the metal is massaged up and outward to make clearance.
