How often should I check the tire pressure in my Audi A2?

I recently purchased a used Audi A2 and I'm not sure how often I should be checking the tire pressure to ensure optimal performance and safety. Could you provide some guidance on how often I should check the tire pressure and if there are any specific techniques I should be aware of?

It is recommended to check your tire pressure at least once a month. However, if you frequently drive long distances or in varying weather conditions, it is best to check it more often.
