Can I use a car tire pump on my bike?
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.
How do you inflate a fully deflated bike tire?
You can easily inflate a completely flat tire (provided the tube is still good). Usually, when a tire is completely flat, you have to press the back of the tire so that the valve doesn’t recess into the tire so your pump can be attached properly to it.
Can I use an air compressor to inflate bike tires?
You can use an air compressor to fill a bike tire much faster than you can with a manual pump, but there are a few things you have to watch out for – especially if you are trying to air up the tires of your mountain bike at the gas station.
