1) Always inflate your tires before every ride. Use a floor pump designed for bicycle tires.

2) Never, ever use an air pump at a gas station. They don't provide enough pressure, anyway, and they provide too high a flow rate. You'll likely damage at least the tube, if not the tire, by using one.

3) Learn how to use a patch kit, and carry either a mini-pump or a CO2 inflator. You should never have to walk your bike if you are prepared.
