To the fella in dubbo who asked me a while back how many 4x4 tyres can i pump up with my portable small oxy bottle and the air line,,,
well the answer is 30 tyres from 12 psi up to 35 psi and the bottle sits in the cradle on the
barn door behind the one of the spares. It is as quick as a servo.

NEVER USE OXYGEN to pump up tyres - you risk serious injury from explosion - I hope you meant air. Oxygen and oil is explosive under pressure, ala diesel and other compression ignition engines. Similarly, the oxygen cylinder will have a warning about its use on it -
Check with BOC gases if you need to. The best gas to use is nitrogen as it is completely inert and pressure does not fluctuate with temperature of tyre - long haul trucks have used this. Next best is plain air (scuba tank) problems with annual
check of cylinder. The cheapest and longest time between fills is Co2 (carbon dioxide) as used by the RAC, as it is a liquid under pressure there is a weight factor to be considered.
Cheers, Jon
