use of co2
has enyone checked the differance of tire pressures after tire heats up when using co2
went to the local air gas store to price a tank and the gentleman there talked me out of using co2 due to it being an unstable gas that can increse tire pressure to dagerous levels when heated

Great question. Air expands/contracts within a few pounds of pressure on a 30~35psi normal size car tire. I'd expect the same few pounds of pressure range on a 35" tire, although there is more 'capacity' in the tire, and normal driving is up around 40~50 psi. There might be a little more range because of the increased psi? 
So the question is...for the range of heat generated in typical driving and weather conditions...does CO2 expand/contract more or less than regular everyday air?

For what it's worth I air down to @ 15 psi and after the run I take it back to @ 37 with C02. The next day the pressure will drop @ 5 pounds. I have not had a problem with C02 expanding to a dangerous point that I know about. If you had nitrogen and were to air aown I can see the $$$ flowing away..
Best of luck.

thats what im gonna do. i dont care to run nitrogen; im more so weighing co2 vs air compressor. im sure ifit were that big of a difference, it would be well known

Here is what will sell you...
Go wheeling with me.. after a day of fun and its air up time...
I get my hose connect to Co2... you crank up your on board compressor.
You get done filling up tire one.
I am reeling up my hose to put it away because I am done all four and I am now watching you still bent down on your knees going for tire number 2.
And hey...while your down there......
