Tyre pressure should be checked regularly, ideally once a month, and also before long trips. The best time to check tyre pressure is when the tyres are cold — meaning the vehicle has been parked for at least three hours or has been driven less than 2 km at a moderate speed. This gives the most accurate reading because driving heats up the tyres and increases the pressure, which can give a false high reading. Checking tyres when cold helps avoid under- or over-inflation mistakes. Additionally, the spare tyre's pressure should be checked occasionally as well. Key points:

• Check tyre pressure monthly or every two weeks for some recommendations.
• Check tyres cold (after parking for several hours or minimal driving).
• Use a reliable pressure gauge.
• Refer to the manufacturer's recommended tyre pressure (usually in the owner's manual or driver's door frame).
• Check before long trips.
• Include spare tyre checks.

Maintaining correct tyre pressure is important for safety, better fuel efficiency, optimal tyre life, and vehicle handling.
