Or... just use some cans of fix a flat, or if it's really that bad, use the mini spare. I mean honestly, how often are you getting flats, and if it's a daily driver you're probably not commuting in the desert somewhere, so you have ready access to tire shops for repairs and such. Though remember to tell the tire guy that you put in the fix-a-flat. They get kinda pissed when you don't.
