Outer Limits 4x4 Board

I've seen/read about people mounting air tanks with all the fittings to mount up to an air compresser. Do these tanks have enough to pop beads back into place? If people have how many litres is the tank, what is it off?

Thanks for the help.

Hobzee has some great Alloy jobs. They are super light weight, come in various sizes and of course won't rust!

I use a 15 litre which is enough storage to pop a bead or undo 6 wheel nuts with a rattle gun before the compressor cuts back in.
