Hmm sounds like alot of $$$ to me. Either a whole new facility to mass produce these or alot of retooling.
And since when did the auto industry want to start making stuff that lasts longer ?
used runflats on my harley a few years back,cost was close to normal but local harley dealy would not take back the carcass of them when i replaced them
retreads are what you see lying all over the damn highways. They shouldn't be legal, those things can kill people on bikes, or even people in cars if they come off just right.
