What can I use instead of a bike pump?
For emergency situations on the road or at home, when no pump or air compressor is available, you can inflate bike tires quickly using a compact compressed air or C02 inflator designed for bicycles.
Can you inflate a bike tire with a car pump?
The long answer: The reason you can sometimes use an automotive air-pump on a bicycle tire/tube is because they share an identical valve. (See: Schrader valve/Schrader tube in the Terminology Index). If you have this type, you will definitely be able to get air into your tubes in a pinch.
