I think that depends on whether other mfrs start using the run-flat system.
Remember back in the late 80s, only BMW, Ferrari, Ford Mustangs and maybe
another mfr or so used metric tires. Once those cars ended their production
cycle, and tire mfrs saw nobody else using it, metric tires were doomed.
I don't know how many other mfrs are using run-flats, but if it cuts
production cost and save weight, its going to be attractive to them. If that
is the way things are going, then let's hope everybody picks up on it.
Otherwise, it can be an expensive lesson for those with it....
