How many 16 gram CO2 cylinders for a 17" tire?

 Regarding those CO2 tire inflator kits, anyone know how many cylinders it
takes to get a rear 180x70x17 tire back up to 40 psi?

Dealer says a lot, maybe 7-8 cylinders.

Anyone need to use one?

Dealer might be right.  I had to use the one that came with a BMW and three
didn't even make a dent in it.  Of course, some leaked out of both the the
stringy stuff they call a plug and some more from the funky adapter for the
C02 chuck.  Ended up needing to use a can of Inflate-a-Flat in a larger
spray-type can and tire still wasn't fully up and wobbly.

I believe after the ordeal those C02 things were designed for bicycle tires
and not motorcycle tires.  They say that one 16 gramer can inflate a
'Mountian Bike (i.e. bicycle) Tire" to about 40psi.  That's going to be a
lot of motorcycle tires.

Get a compressor like maybe the "Slime" one.  It's volume would amount to a
dozen of those cylinders and you'd still have fudging room should it still
leak.  It doesn't cost any more than a dozen of those C02 things.

Not yet. I think BMW packs two or maybe three in their puncture kits
(I'd have to check), and so I'd assumer they know the reality, and pack
that many.

Be aware that some of them, probably most of them, are utterly
shit and you are rolling the dice hoping to get a half decent
one that will last through inflating more than one or two tires.
I'm on my 2nd one after the first lived through a fair number
of flats on the car before being relegated to bike duty.

Also, you may want to fashion some sort of minimal shroud
around the big end/reduction gears so that you can safely let
the pump lie on the ground, it gets tedious holding it aloft
while waiting for a tire to inflate.

Also if SWMBO volunteers to hold it while you are inflating
her Ninjette tire, tell her to keep that shop rag away from
the gears, thank goodness for spare fuses.
