Disclaimer: i am fortunate so far to have never had to use any of this to repair a flat tire, with the exception of using the portable compressor once to air up a low tire.
I have a harbor freight aluminum floor jack that breaks down and fits in the trunk. I dont keep it in the trunk at all times, only when I go on long road trips. If I have a problem close to home i'll probably call a friend or AAA.
I keep stowed in the trunk at all times a portable air compressor and tire repair kit:
The tire repair kit i got from Amazon:

The compressor came from Griot's Garage, and has two modes: air only, or also the sealant goop.

I figure this is good cheap insurance in the event I'm completely stranded. Hope I never have to use them.
