How to properly check the tire pressure in a BMW Z4?

I recently purchased a BMW Z4 and I want to make sure I am properly checking the tire pressure. Can you provide step-by-step instructions on how to do this?

First, make sure you have a tire gauge that is compatible with your BMW Z4. Then, turn on your car and let the tires warm up for a few minutes. Once they are warm, unscrew the valve stem caps and place the tire gauge on the valve stem firmly. Take note of the reading and compare it to the recommended tire pressure listed in your car's manual. If the pressure is too low, use an air pump to add more air. If the pressure is too high, use the tire gauge to release some air.

Another method for checking tire pressure is to use a digital tire pressure monitor. Simply turn on the monitor, place it on the valve stem, and it will display the current tire pressure. Again, compare this to the recommended pressure in your manual and make any adjustments as needed.
