Use a tire pressure guage, which is available at any gas station at the cashier's desk.
Check the pressure when the tire is cold. The number on the side of the tire is for when the air inside is cold (heat causes air to expand and creates more pressure).
Normally, the first number on the tire is the "pounds per square inch" measurement. The second number is the metric equivalent. Whichever number is relevant to your country's measurement system is the one you use to see if you have enough or too much pressure.

At the store you can purchase a pressure gage. Most are a stick guage. Take the cap off the air thing on your tire and insert the guage. The stick will rise and the number it reads is the pressure. (Your tire should tell you what the suggested best pressure for it is.)
Or you can buy a digital one. Put the end on the air thing (no cap again) and you push the button. The screen should read to you the pressure.
Most guages come with their own directions.

1) Find the biggest knife in your kitchen.
2) Insert said knife into tire.
3) Count, in seconds, how long the air hisses out of tire.
4) Multiply that number by 38.763, without using a calculator.
5) Add 2 to your answer.
6) Write THAT answer on a piece of 8.5x11 plain white paper.
7) Fold said paper into 4 quadrants
8) Place paper in oven at 375 degrees F
9) Bake for 346 seconds.
10) Remove paper. (Careful, it's hot)
11) Fold paper into a paper airplane.
12) Throw airplane out window
13) Count, in seconds, how long it flies before crashing.
And that's how much air pressure psi was in your tire.

If you are driving and feeling like having a low pressure in your tyre... then stop and touch the typre(s), if its normal warm, its OKAY. but if its hot then it is low pressure and if cold, then over pressure (which may lead less effective breaking).

Go to an auto store and ask for a tire gauge.
