What Car? investigates: tyre safety - Buy your own tyre gauge

A survey by The AA revealed that as many as 40% of pressure gauges on petrol station forecourts are inaccurate. So the best way to keep your tyres at the right pressure is with a quality pressure gauge of your own. Here are three ideal, reasonably priced gauges:

1. Michelin digital gauge
Where? www.tyre-equipment.co.uk
How much? £17.51


2. Accutire Pistol Grip MS44B
Where? www.speeding.co.uk
How much? £9.99









3. Halfords dial gauge
Where? www.halfords.com
How much? £9.99


• Some modern cars have in-built tyre pressure monitors. Such systems can alert you to an under-inflated tyre before it's too late, so look out for this feature when buying your next car.
