You left the nuts on the old wheel, so that you wouldn't lose them. Now it's time to remove them.

• Spin all the lug nuts off with your hand, and put them aside (in the hubcap if you have one, or on the tarp).
• Grasp the wheel by two sides of the tire (at the three o'clock and nine o'clock positions). Pull the wheel straight out and off. Keep your weight forward or you'll fall backwards and land on your butt. Roll the old wheel to one side.
