I run with a jack and "dogturd" plugs as well as mobility kit + NRMA membership.
First point of call is the dogturd. Jack is used to get the wheel off for better access.
Next point of call is the mobility kit if it is in a location a dog turd is not suitable
Next is NRMA for when the sidewall is FUBAR.
If it is a long trip in country NSW i'll take a full size spare (space saver if i had one)
