My apologies if there's an FAQ on this I didn't find. Redirect me if appropriate. I haven't been carrying a jack and tools to change a tire if necessary; in general, I have road service for that. ...
Lots of good suggestions for the challenge of tire changing. I carry a torque wrench multiplier which helps me get the gorilla tighten lug nuts off. Just have to make sure you are turning in the right direction. Cheap and (although one can break the bank getting high quality ones.) no power or batteries needed.
