How often should I check tyre pressure?

Tyre pressure check frequency

Check your tyre pressure at least once a month and before any long trip or journey with heavy loads. It only takes a couple of minutes at a petrol station or with a home pressure gauge, and it can make a real difference to your safety and running costs.

Why monthly checks matter

Tyres naturally lose approximately 1 to 2 PSI per month through normal permeation. Seasonal temperature changes can also cause pressure fluctuations. Without regular checks, you could be driving on significantly underinflated tyres without realising it.

Do not rely on TPMS alone

If your car has a Tyre Pressure Monitoring System, be aware that it typically only triggers a warning when pressure is around 25 percent below the recommended level. By that point, the tyre is already significantly underinflated. Regular manual checks catch pressure drops much earlier.
