I don't use CO2 cartridges, but I believe you can use them on any size bicycle tires.

I use a Topeak RoadMorph pump and haven't seen any need to switch to anything other than the pump. I don't like the idea of creating more trash every time I need to deal with a tire problem on the road. (OK, OK, I may be in the minority on that one, but it's still the way I feel!) If you choose to go with cartridges, I hope you have a place where you can recycle them.
