I have been mounting and balancing tires at home for years but I want to replace the helper for stubborn SUV beads with a bead blaster bead sealing bazooka.

These portable tire bead sealers blast air into the bead as you're filling it, which is useful for one-man tire mounting efforts on those stubborn tires that just won't seat without help.

My question is for those of you who already mount your tires at home and who use the bead blaster bazookas.

Which size is best?

• 2-1/2 gallons?
• 5 gallons?
• 10 gallons?

The price isn't that much different but the size is.
Also I'm wondering if the tank is useful as a source of portable compressed air (in which case a larger tank might be better perhaps?).

What are your recommendations for the SIZE of the bead bazooka blaster?
