Like several others, I carry an inflator, slime, a plug kit, and have emergency roadside service with my insurance.
I haven't had a flat (that needed changing) since the 1980's (or early 90's maybe). I've been carrying a big ole spare around on my "other" van for 130,000 miles. I'm not sure I could get it out of the continental carrier if I needed to. The "slime" people "claim" that 96% of tire problems can be fixed with their product and an inflator. Hopefully, if I get one of those 4% type flats, I'm within cell range
