How do I check the tire pressure in my BMW 1 Series?

I recently bought a BMW 1 Series and I'm not sure how to check the tire pressure. Can anyone give me some tips on how to do it correctly?

First, you will need to locate the tire pressure label on the driver's side door jamb. This label will tell you the recommended tire pressure for your specific vehicle. Next, you will need a tire pressure gauge, which can be purchased at most auto stores. Simply press the gauge onto the valve stem of each tire and check the reading. If the reading is lower than the recommended pressure, use an air compressor to inflate the tire. If it is too high, release some air. Remember to check the pressure when the tires are cold for the most accurate reading.
