How to Check Tyre Pressure

By the Super Simple Digital Tools Team · Updated June 2026 · Easy · 10 minutes

Correct tyre pressure improves fuel economy, handling and safety, and makes tyres last longer. It takes two minutes with a gauge, and most petrol stations have a free air pump.

Steps

1. Find the right pressure. Look for the recommended PSI on a sticker inside the driver's door frame or in your owner's manual — not the number on the tyre itself.
2. Check when cold. Measure before driving far, as warm tyres read higher. If you've driven a while, allow 30 minutes to cool.
3. Read the gauge. Unscrew the valve cap and press the gauge firmly onto the valve until the hiss stops, then read the pressure.
4. Add or release air. Use the pump to add air, checking often. To release air, press the small pin in the centre of the valve briefly.
5. Replace the caps. Recheck all four tyres (and ideally the spare), then screw the valve caps back on.

Tips

• Check pressure at least monthly and before long trips.
• Increase pressure slightly when carrying heavy loads — see the manual for the higher figure.
