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.

This is quite an interesting alternative to a compressor. What's an oxy bottle worth? The only thing that worries me about this is the tendency for things to burn faster in an oxygen rich environment. I wonder what the effects in a tyre could be.

Hi Voxson I am not the fella from Dubbo but am interested in your setup.I have read the posts from Goran April/May 2002 who uses Co2 to inflate his tyres.I would like to know costs/sizes of bottles what sort of regulator type/length of hose used.I suppose you could use air tools etc
which would be a great advantage over normal compressors..Do you know of any web sites that feature this system..Thanks in anticipation Greg g

I am not sure of the cost of my bottle which is a small dive unit. I have it mounted into a holder on the back door with about 500mm of airline from my regulator. I take it to each tyre in turn. It is very portable with a little handle as part of the neck. I use a small amount of line because i hate tangles. I aquired the bottle from a friend a while back. The ongoing expense of bottle checking is no issue to me because the shear air speed keeps me happy.

Hi Voxson I think I have just answered my last question.I found an American site www.powertank.com (not to be confused with the Bushranger Power Tank) which uses Co2 looks good apart from the price
but like most things could be coppied rather cheaply.regard Greg g

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

I have been using a CO2 system similar to Gorans .I purchased a 10kg CO2 bottle and an argon regulator with air line fill valve and presure gauge allup about$170 it takes about 30 seconds to inflate each tyre from 20psi back to 40psi .I can inflate aprox 60tyres with one fill it ,also wks air tools or diff locks
