20. Spin To Win

How To: When your tire has 15 to 20 pounds of pressure, remove the pump from the valve. Spin the wheel and inspect it to see how the tire is seating. You especially want to watch for any bulges on the side of the tire that might indicate that the tube is underneath the bead. When this happens, the bead will not lock properly under the lip on the rim. Inflating the tire more will push the tire bead off the rim and you'll explode your new tube in a thunder crack of failure. Sometimes the tire is sitting funny, and a little massaging the bead into place is all it takes to get it seated evenly around the rim.
