How do NASCAR pit crews change wheels?

Answer 1

During a routine pit stop in either series, the tires are laid out and three of the four tire changers are pre-positioned before the car enters its pit stall; the fourth tire changer, whose responsibility is the rear tire on the far side of pit road from the pit wall, doesn't take his position until after the car arrives, due to a rule against having the car run over the feed hose for the impact wrench used to change the tires.Simultaneously, the four tire changers remove the tires and install the new ones. Once the tire changes are complete, the front tire changers may use manual adjusters to adjust the angle of the car's front wing.

Answer 2

The same way street drivers change theirs, with two differences: NASCAR teams have multiple sets of rims so they can just pull off one set of tires and bolt on a new one; and NASCAR teams change the lug nuts at every stop.
