The lift mate does not really work to change a tire. It works to get something under the tire or axle though and can be used to reset the bead if it came off.

In all honesty, that situation I was in was unusual due to a worn out crappy tire that was aired down too much. Once it lost the bead... it ripped the sidewall. If you keep your air pressure right and use a good offroad tire (the durability has gotten to the point where I don't even worry). You probably won't ever have a problem that can't be fixed with a plug to at least get you to stable ground. Spares are still necessary, but the frequency of use has gone way down from my experience. I have not had a tire failure in years now. Even in brutal conditions. I have hurt tires, but they are always good enough to drive off the trail on. But I only run MTR radials and bias plys.... If you are on a P tire.. all bets are off. Point is, best safety/recovery equipment possible is a good tire. Running P tires on trails.. is just inconsiderate to everyone else trying to use the trails IMHO. Stay on very moderate stuff if you run a street tire.
