Properly inflated tires will help your bike move smoothly and comfortably. It's important to have a quality air pump on hand if you ride a bike often, so you can keep your tires well-inflated at all times. There are several indicators that will let you know your bike tires are low. It's probably time to inflate your tires if you: Can feel the rim hitting objects when you ride over them. Feel unsteady on the bike. Have difficulty turning. Can see the tire sagging when you sit on the bike. You should be able to pinch your tire inward just a few centimeters when gripping it on the sidewalls. If you can't pinch the tire at all, it's probably overinflated.
