Had a flat (non-RFT) last week, took 15 minutes to change tire, and got tire fixed for $35, so I'm not sure what the advantage of run flats is, unless you are unable to change a tire I suppose. (but then you probably have ama or some other roadside assitance). So why is bmw doing this; just to save space and cost? seems very short sighted for such a sucessful company. Anyways, I may leave the bmw fold if they don't change this policy.
