NASCAR Racing: Tire changing, center hub, quick shift


Question
"So when the wheel is slid onto the hub and the holes are slid over the lugs.."

How do they get the hoes for the lugs to line up so quickly?

Answer
Actually, it's pretty simple....the center hub sticks out far enough to catch the wheel before the lugs line up and center the wheel. Then it's as simple as having lines painted on the center hub that line up with where the lugs are. The wheel just needs a quick shift in either direction to line up the holes with the lines on the center hub and push. It's on.
