Loosen Bolts before Jacking Up the Car

p. 20

You see what happened there? Pete didn't loosen the bolts before jacking the car up, which then means when he wants to put pressure on the bolts and there's no road to stop it, the wheels just spin. Dumb Pete.

Here's some resources to support the statement.

Loosen Lug Nuts Before Jacking Car

Once you are ready to start changing your tire you will want to first loosen the lug nuts before you jack the car up at all. Many times your lug nuts are tightly installed on your tire. Loosening your lug nuts can require a lot of force. Having your tire on the ground and the weight of the car on the tire still will help prevent the tire from just spinning as you loosen the lug nuts. Source
