How Long To Get A Tire Replaced Via Roadside Service

We had a blowout in the middle of nowhere Texas about ten years ago. Called Coachnet, in about an hour, a guy came out from a truck tire place, and changed the tire for a new one he brought out with him. We then followed him back to the truck place to get the tire/wheel balanced. I checked around, he charged us less for the tire than any other tire place I could find.
