What to look for
Digital vs dial: digital wins for accuracy and readability. For home use, a £10-15 digital gauge is better than a free forecourt gauge (which are often inaccurate by ±5 PSI). Check tyres cold — driving heats air and raises pressure by 4-6 PSI.
Frequently asked
How often should I check tyre pressure?
Monthly and before any long journey. Most tyres lose 1-2 PSI per month naturally through permeation. Temperature changes also cause pressure changes — tyres lose about 1 PSI for every 6°C drop in temperature.
What's the right tyre pressure?
Check the sticker inside your driver's door jamb or the owner's manual. Never rely on the tyre sidewall — that shows the maximum pressure, not the recommended pressure.
