Well after wheeling for almost 10 hours yesterday, a buddy popped a bead going up a hard packed slick clay mud hill. Not having a spare or a power tank, we were a little worried that his
wasn't going to supply enough pressure to re-seat the bead. But after jacking the truck up, it worked perfectly. I was amazed and relieved!

So, in conclusion, why spend the high dollars on a Power Tank or other CO2 system, when for less than $50, you can pump all four of your tires, re-seat a bead, and still have air left? After seeing that, I see no reason to spend the extra money on a Power Tank or similar system.

I am thinking that you got lucky on that working. I have never heard of anyone else having enough pressure in a tank like that.

The Physics of the air volume of the tank versus the air needed for 4 tires and a bead seem to be in conflict with the volume that tank should hold.

I am not going to argue about the validity of your experience, but it sounds like you may be revolutionizing the air source market if this works.

Well, it is a 10 gallon tank, that's pretty big. I'd guess it should have enough volume to seat a bead, but not very many people want to carry around something that big.


A trick to seating a bead is to use a ratchet strap around the circumfrence of the tire to help seal the gap. Then a decent air compressor can seat the bead.

Yeah, I though it would never work after hearing how much pressure everyone discussing needing to make it happen. What was even crazier is that he pulled outward on the tire as I put the air in, and sure enough it worked like a charm. I've never done it before, and it was pretty cool to see it actually work.

Just to clarify something. You really don't need that much pressure, it's the volumetric flow that really matters. The power tanks can deliver high volume fast, at high pressure...same with a big air tank. You'll have a hard time seating a bead with a walmart special that can put out 300psi (that's where the strap may help).

you could always use ether and a match to re seat a bead! kinda dangerous though! although i have heard it to have been done before

:fireman:

Where are you finding these tanks that hold 300 psi, because the highest I've seen is 135 psi? I'd love to have the same size or even smaller tank with over doube that in pressure.
