Quick Change
How do they get the tires on and off so fast?
You may have seen a NASCAR pit stop before. In 12 to 14 seconds, seven people manage to completely refuel the car and change all four tires. This requires incredible hand-eye coordination, but there are a couple of tricks the teams use to make things a little easier. When the new tire is placed onto the car, the five lug nuts are already attached to the wheel by an adhesive. The studs are long and have no threads for the first three-quarters of an inch. This ensures that the lug nuts do not get cross-threaded, making it easier for the tire to be positioned.

Air powered tools. And the car is lifted with a jack. I think they only have to move the handle down once to lift the car up.

A specially designed pneumatic jack to lift the car, and specially designed lug nuts on the tires.

Air compressor. They use an air lift jack and air wrenches, both powered by an air compressor.
