A portable inflator turns a soft tyre into a ten-minute stop rather than a call-out, which is the case for keeping one in any vehicle that spends its day away from a workshop. The Altius ALT-TYRE360 runs to a maximum of 150PSI, so it covers car tyres, the much higher pressures a road bike needs, and sports gear like balls and inflatables from the same unit. Compact enough to live in a glovebox or a door pocket rather than taking up boot space. Sensible kit for a service vehicle, a sales car, or a site vehicle that works well away from the nearest servo.
