Continental DWS issues

[igota21incher]

Just replaced the original bridgestones after 27k miles with a pair of these highly recommended all seasons. First thing i notice after the switch was how soft these side walls really are. No biggie. My issue with these tires is that i feel a pretty noticeable shaking of my steering wheel at speeds >60 never had this issue with the old set so i dont think its an alignment problem. My next complaint is how disconnected i felt with the steering wheel, with the old set any slight turn i would feel right away, now there is a little play that i noticed when moving it slightly left to right without the car actually giving me any feedback of this adjustment. Is this just the nature or this tire overall or am i looking at something a little bit more complicated involving incorrect balancing or an alignment problem? Thanks!
