I agree with everyone you shouldn't rely on 3 small canisters to inflate the tyre. 3 of the small ones does about 8 psi per canister. Enough I guess to get you out of the countryside perhaps (if you've actually plugged the hole). That kit is better, because the inflating tube doubles as a small pump, but you'd pump other things with a lot more success than a tyre... unless you have all day
I've got a cigarette outlet plugged into my bike and one of these: http://www.advdesigns.com/mitipukitba.html
Tis done a lot of work that little pump... including inflating bike tyres for a whole group...
