What tyres for a better ride?

I have a 2003 BMW 320d touring sport which is shod with staggered 'run-flats' - 255/35/18ZR (rear) and 225/4018ZR (front). The ride is too harsh and tramlines a lot too. I'm considering switching to 17" rims - what 'non- run-flat' tyres would you recommend for improved ride and handling?

Michelin Pilot Sport 3 or Michelin Primacy 3. Same size front and back. May need re-aligning and the steering angle sensor re-set.
