I also think your pressure may be a bit high. I would have thought that the pressures for an e46 coupe sport with similar sized mixed tyres would be a good indicator:
That site is talking about 36/40 psi which is more like 2.5/2.8 bar.
I would have another word with the tyre fitter about the pressures.
Well my tyres were on 2.6-2.7 originally.
Anyways now with 3.3 bar ... it drives bad BUT taking corners is awesome! I don't think run flats can't be more bad in ride comfort then tyres @ 3.3 bar. My car is at the dealer, I will have it back tomorrow with Bridgestones RFT. The ones that came with the car.
I hope everything is solved then.
