Anyone who says otherwise has not made the rft-->non-rft switch on 19" wheels. He cracked one of the wheels when he had the runflats mounted but despite moving to downtown Baltimore where the roads are horrific he hasn't had any issues on the non-rft tires.
I am a firm believer in non-rfts to save the wheels. My soft gravity cast m6 replica wheels have lasted 3 years and still have no cracks/bends despite my fully modded suspension and hitting potholes head on that cracked my brother's 135i 18" msport wheel (also using 050a runflats).
Great post & thanks strat...Agree on all fronts I too would remove those horrid RFT's as they "are" the cracking culprit no doubt. On the bright side flipping tires will save you nearly 5 hundred $$$ compared to purchasing Rim/Tire insurance priced @ 1,600 Ouch!! 19's with run flats do not work BMW!!! 18's there's a prayer of a chance.
