How often should you check your Ford Focus's tire pressure?

I just got a Ford Focus and I'm wondering how often I should be checking my tire pressure. I don't want to risk damaging my tires or decreasing my fuel efficiency. Any advice would be greatly appreciated!

You should check your tire pressure at least once a month. This will ensure your tires are properly inflated, which will improve your fuel efficiency and reduce wear and tear on your tires. In addition, it's always a good idea to check your tire pressure before a long road trip.

It's also a good idea to check your tire pressure when there's a drastic change in temperature. Cold weather can cause your tires to lose air pressure, so it's important to keep an eye on them during the winter months.

Don't forget to also check your spare tire's pressure. Many people forget about their spare tire until they need it, and if it's not properly inflated, it won't be of much use in an emergency.
