I have a 2013 BMW 335i xDrive sedan on order with 19" 401 Style wheels.
I am actually glad tires are run flat but may have to resign to the fact that tires will be replaced at some point.
My SUV has Goodyear Fortera Tripletred tires. These tires simply ignore any road debris - never had a problem of any kind. But - it's not a fair comparison.
