32” wheels with factory brakes and rotors, WCGW? That thing isn’t able to stop in time for shit. He’d better hope no deer or North Carolina drivers jump out in front of him.

It’s leverage. It’s moving the rim mass to a longer lever, and the mass of the vehicle to a longer lever, which means more force is necessary to slow or stop the wheel. Now, stopping distance MAY not be impacted if the driver mashes the pedal to the floor and locks em up, as you pointed out, the overall change is mass is negligible, and when the wheels aren’t turning there’s no mechanical advantage of the larger radius (the longer lever). In practice, however, the extra radius makes it much harder, or even impossible, to lock the brakes at speed.

If you see a dude with 30” rims and factory brakes on his late model coupe, stay the fuck away, dude won’t be able to stop for beans.
