I have been crossing the boarder to race for more than 30 years .The boarder always looks at my cutting torch tanks if they look at my stuff at all but
not my scuba tanks.
I will repeat myself I have never had a problem at the boarder coming or going. I don't think I fit the profile they are looking for,every time ive been
held up its because the officer thought my car was cool, I always take time to answer any fans questions,so this was no bother to me
Tanks are rated at a 4 to 1 safety rating that means that a 3000 psi tank has been tested to 12000 psi ,and they are rated for various beathing gasses
that do expand with heat nitrogen does not. nitrogen is a much bigger mollicule than oxegen. It does not leak as much as air. oxegen will bleed
through a tire .The air that we breath is 70% nitrogen 30% oxegen anyway . nitrogen is not that dangerous just don't try to breath it
in its pure state its no different than a fire supression system in this way . I don't ever use any liquid to pop the bead on I use
charcoal streight out of the fire pit, it will get them on and it seems to get absorbed into the tires or somthing, Ive heard some of my older freinds call
it (black bead lock) it realy holds a tire at low pressure. When I do mount a new tire I always leave it over night at 40 psi then bleed it down in the
morning this helps to set it good . I use a paintball regulator, you can also run an impact or ratchet off one of these tanks ,hell even a nail gun if
you feel like it.
I got my tanks filled at Sgt. Splaters in TO I never paid more than $20, there must be a paintball place in Ottawa that will fill tanks ,
try looking up paintball Ottawa on google . My tanks are current and US Customs ,Canada Customs and the NHRA saftey
safari never had a problem with them ,and beleive me the NHRA is huge on saftey.
I don't know anything about this at all but I have been told that hellium in a tire will reduce your unsprung wheight ,seems to make sence .
Does anyone know anything about this?
