Q: How do I put air in my tires when I have those funny, skinny valves?
A: Those funny, skinny valves are called presta valves. To inflate your tires when you have presta valves, you have to first unscrew the little nut on top. Turn it counter-clockwise until it stops. It won't come off. Then you have to use either a bike pump with a nozzle designed to fit presta valves, or install an adaptor.
