RING RAC 635
TYRECOMPRESSOR AND GAUGE CORRECT tyre pressures are vital for optimum roadholding, braking and economy. Even if your car has a tyre pressure monitor, it pays to check levels regularly and adding a few psi is easy with a 12V compressor. The RAC 635 has an accurate digital gauge, LED light and preset function. But don’t lower pressure to boost grip in snow – it reduces stability and leads to overheating once back on tarmac.
