What pressure from a CO2 tank to seat and inflate tubeless?

[Lugboot]

How's that for a question? I want to use a CO2 system as double duty for tubeless mtn bike tire seating/inflation at 24 hour races. The cheap regulators on the systems are preset around 150psi. Is this too high? Should I opt for an adjustable regulator on a CO2 system? If so, what pressure should I set it at for bike tires?

Thanks!

Never mind. I answered my own question. I can work with 150psi. And this will help control the flow.

Good stuff.

I don't use a regulator at all, other than the valve. It works, and it doesn't freeze up after two tires. You do have to be careful not to turn the inflator into a projectile.
