"4 x 16gm will fill Motorcycle 180/55/17 tyre to 32PSI/2.2BAR"

The standard BMW kit has 3 which gets the rear tyre close to opperating pressure, good enough to get you to somewhere where you can check and add a bit if you have to.
 
After you have plugged a tyre and used all three cartridges, only to find that the plug is leaking, you may want to give up with CO2 and buy a pump. Much better solution.

CO2 cartridges got Ferret back to camp last Sept, when trying to fix the puncture would have been nigh on impossible as it had gone dark. A pump wouldn't have put gas in quickly enough to inflate & ride on but each CO2 cartridge got him about 5 miles with the slow leak he had got. You're right that you can run out of cartridges & can't with a pump, but they work much more often than not & are much quicker when you're on the trail. As a group, we always have both available...

Great price BTW & they are the same people behind the Co2cartridges.com site. Check out their Innovations Ultraflate gizmo which, at £5.99, is a bargain tyre inflator.
 
I read somewhere that C02 will bleed through a tyre wall and so any tyre pumped with these cartridges should be inflated properly with air at the earliest opotunity.....Is this true? I don't know so so just asking if its true.

Here is my view.

I don't always carry a pump/compressor with me, so a few cartridges fit under the seat in case of emergency.

As you can not get exact pressure using the cartridge, then a visit to a source of air should be made at the earliest opportunity.

It is all about piece of mind.

And when you have emptied your cartridges you need to replace them, so I stuck a link to a supplier of cartridges.

CO2 is denser than Nitrogen (N2) which is a major component of air so there should be no unusual bleed through. Some high end tyres are filled with Nitrogen (although this seems to be more money than its worth unless you are in specialist aviation or high pressure diving). You may be thinking of Hydrogen or Helium which has a tendency to bleed through most containers (storage is one of the problems with Hydrogen Fuel cells if you are thinking of installing one).

By all means do a search, but didn't Steptoe mention months ago that these won't get the pressure up to normal, because the pressure in the tyre would be greater than the pressure in the cannister? :nenau

I'm sure they'll get you out of the cack and it's worth keeping a few handy though. :thumb2 If you get the chance, keep your hand on the tyre when you put the cannister on. The first time it was a bit of an eye-opener to feel the tyre expand so quickly. :eek

Just a thought, but the 2 cartridge pack works out at £3.50 a cartridge, while a box of 50 12Gm cartridges works out at 30 pence a cartridge. Could be worth splitting a pack?
