Cheers and welcome to Bike Forums.
Pics of your bike and valves in tyres would help. There are about 3 common valve designs ("common" also depends on where you live), odds are you have a wrong kind of pump for the valve in question.
BTW, I'm moving this to Bicycle Mechanics (from General).

Most likely at least here in the US, you have tubes fitted with Presta valves (the top of the valve looks like a series of stacked parts, each smaller than the one below). Most automotive-type valves are Schrader (top of the valve is pretty much flat right across.).
You can either go get a bicycle air pump (most will handle either type of valve), or pick up a few cheap presta-to-schrader adapters. Most bike shops around here have them for around $1 each.
If you aren't in the US, I'm not sure what you may have. I know there is a 3rd type of valve, but it's rare here and I've never had direct experience with it.

agree with the above, yo uprobably have presta valves which means you can't just go to a gas station and fill up without having a valve adaptor. Another thing to note is that many aircompressors don't get up to high enough pressures to make them suitable for pumping bike tires or you can have a case where they fill up too fast like at a gas station that has very high pressure high volume compressors because they use air tools. A good old footpump is the best way and can be had for relatively short money. Most of the time you will just be topping off the air every few days.

If your bike has presta valves...
... and you want to use a shrader pump, you can use an adapter like this...

For comparison, Sheldon Brown has a pic of all three valves (Presta, Schrader and Dunlop) side by side.
