Dunno...it seems the "article" was referring to Bridgestone RFs.
My first & only exp w/RFs is on my VetteVert, currently. They came w/Goodyear F1 RunFlats or RunCraps as they are called on the VetteForum. In my experience, over the course of 25,000 miles in 3 1/2 yrs, they are "ok":
-they stick pretty well
-they have become noisy during the last 5K miles, but the Vette is noisy anyway
-they have some "feathering" on outside front edges; may be a bal. prob and I hammer the corners around here pretty hard.
-they do have a modicum of "safety net", though the prob is the 50-100 mile drive which becomes really a search for a high end tire joint that has your replacement tire and Knows how to change it w/the internal wheel sensors. Could be problematic on a long trip...it IS problematic here in hillybillyheaven.
-the "reports" of a tire "exploding" or catching on fire seem way overblown, but WTFDIK? I don't recall Any posts on this catching fire situ on the Vette Board.
None of this is BMW Runflat stuff, so it may be an application and/or brand issue.
RFs currently and in near future all seem to have some trade off in terms of ride quality, noise, real world grip, etc., for the "benefit". To call them a safety hazard, in general, or a pieces of crap, is imo, pretty sensational. I may relplace my Vette's RFs with new RFs or, I may go to a non-runflat which requires a m'cycle type patch/plug and pump situ, due to no spare. Nothing beats "regular" tires and a spare of some kind, imo.
They are not a panacea...they do allow Buffy to get her car home or to the stlr, which is the majority of the "marketing issue", methinks.
My Qtr's Up.
BR,md
