Under-inflated tyres result in poor handling, braking and an increased risk of a blow-out. They can hit your wallet, too – research shows running your rubber at 20 per cent below the correct pressure (typically 6psi) increases tyre wear by a quarter. Fuel use goes up by three per cent – and tyre life is cut by nearly a third, too!

So, checking your pressures at least once a week makes sense – and a mini-compressor will enable you to top them up quickly and easily. New designs provide impressive performance, and are very user-friendly, with decent leads and good storage.
