I once saw a program about trucks like these in the arctic. To deal with flats they had some sort of mentod using lighter fluid and a match. They would strip the tire of the rim, plug it, put it back on the rim most of the way, then put in the fluid. When ignited it would inflate the tire, seal against the rim and the fire would go out (no more O2). Cool, but if you get burned up in that deserted place you are in biiiiig trouble.
