Well now with my tyres on 3.3 bar. It feels like I'm riding on bicycle tyres. Steering feels much too light and on the highway I need to correct the steering every second or so, gonna change my tyres back to the original RFT
e90 / e91 suspension is rft specific as well.

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:

http://www.thetyrepressuremonitor.co...sures_bmw.html

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.

I was in my wifes car yesterday (little VW polo) and braced myself for a crash when she went over a pothole .... and the suspension just glossed over it.

I'd have felt a major thump in my car.

That's the price you pay for crisp turn in and zero body roll.

Well all my problems seem solved ... stable cornering and very stable @ 155mph. But they are very harsh, and the tyres make a lot more noise, especially when cornering at a roundabout for example.

so it was the tyres in the end?

sounds like the car wants to crab around corners?! is it worse dependant on what corner you are/were going into to LH/RH?

get an alignment check like i said also gt the car up on a ramp maybe the subframe is bent?
