Changing a flat tire

I use a bottle jack on the frame next to the spring hanger mount. I carry my small floor jack with me too. The one time I had a flat the bottle jack did it. Taking this in a different direction, i also had to add a lug wrench. That one time I had to change a tire I was on a long deserted road. About 100 degrees and I discovered my lug nuts were rusted on. Took an hour to break them loose. I searched and found a Kawasaki high torque 12 Volt impact wrench that I keep with me. An hour to change a tire, still less than waiting for roadside assistance, but I confirmed I am not qualified to be part of a NASCAR pit crew.
