How to choose the right one
Cordless or 12V?
Cordless inflators are convenient but need charging. 12V compressors plug into the car socket and are always ready for emergencies.
Auto-stop
Set the target pressure and the inflator stops automatically – avoiding over-inflation.
How to use a tyre inflator
Check pressures when the tyres are cold, before driving. Screw the hose onto the valve, set the target pressure from your car’s door sill or handbook, and let the inflator stop automatically. Check the reading with a separate gauge occasionally to confirm accuracy.
Emergencies and slow punctures
An inflator can get you home or to a garage with a slow puncture, but it will not fix the leak. Have the tyre inspected promptly. Many modern UK cars come without a spare wheel, so an inflator plus sealant kit is worth keeping in the boot.
Other uses
Cordless inflators also pump up bike tyres, footballs and paddling pools with the supplied adapters. Keep them charged before long journeys and winter.
What PSI should my tyres be?
Most cars need around 30–36 PSI, but it varies by model and load. Always use the figures on your door sill or fuel flap rather than the maximum printed on the tyre wall.
Tyre safety checks
While topping up pressures, check tread depth and look for cuts or bulges. The UK legal minimum tread depth for cars is 1.6 mm across the central three-quarters of the tyre, though many experts recommend replacing tyres before they get that low, especially before winter driving.
Buying tips for UK shoppers
Correct tyre pressures improve fuel economy and grip, and tyres are checked at MOT. Find your pressures in the door sill or handbook.
