My 2007 335i sport came with Bridgestone RFT, It was so fun to drive in summer, specially going on the Ramps which interconnects HWY, If i can recall I had tested this BMW doing ~90 MPH on the Ramp which to me is Cornering and ~150MPH on a straight shoot, the car behave like a car on a Rail Track, But once the tire start loosing the tread you feel the Noise and the bumps get worst, plus cant Run these Tires in the Chicago Snow. If I can afford RFT every season then I will stay with RFT for summer and Winter I will switch to Extreme Winter Tires.
MY current DWS are inflated at 38 psi and they are no way Near the RFT when I go over the Ramps or sudden Stopping or sudden lane changes. RFT Feels like tires made from Metal, non-RFT feels like rubber even at 38psi..
