How often should I check my Audi A5's tire pressure?

I recently purchased an Audi A5 and want to make sure I am properly taking care of it. How often should I check the tire pressure and what should I do if it is low?

It is recommended to check your tire pressure at least once a month. Low tire pressure can decrease fuel efficiency and increase the risk of accidents. If your tire pressure is low, use an air pressure gauge to fill them to the proper psi level as indicated on your vehicle's manual.

In addition to checking the tire pressure regularly, it is also important to visually inspect your tires for any signs of wear or damage. If you notice any abnormal tread wear, bulges or cracks, it is best to have them inspected by a professional to ensure your safety while driving.

If you frequently drive in extreme weather conditions, such as hot summers or harsh winters, it is recommended to check your tire pressure more often. Extreme temperatures can affect tire pressure and can lead to under or over-inflation.
