How can I check the air pressure in my Audi 80's tires?

I recently bought a used Audi 80 and noticed that the tires seem a little deflated. I want to make sure they are at the correct pressure for safety and optimal performance. Can someone provide step-by-step instructions on how to check and adjust the tire pressure?

To check the tire pressure on your Audi 80, you will need a tire pressure gauge. Start by removing the valve cap on each tire and inserting the gauge. The recommended tire pressure for your specific vehicle can usually be found on a sticker inside the driver's side door jamb. If the pressure is too low, use an air compressor to inflate the tires. Remember to check the pressure again after a few days as it may decrease due to natural air loss.

Don't forget to also check the spare tire's pressure, as it often gets neglected. You can use the same tire pressure gauge to check the spare tire and inflate it if necessary.

It is recommended to check the tire pressure when the tires are cold, as heat from driving can affect the pressure readings. If you have been driving for more than a few miles, wait at least an hour before checking the tire pressure.
