You will notice the following with the Michelin PSS
- Smoother ride

- Substantially more grip in dry - and especially so in the rain. In florida tempertures I can't chirp the tires even under full throttle with a 550i. In the rain the car seems almost as grippy as in dry.
- Much more stable over expansion joints
- Slight loss of response on turn-in (same for all non run flat tires but PSS is the best in this regard)
- Noisier on concrete (much noisier buy still quiet on tarmac)

If you do it replace all 4 otherwise you will get oversteer given the grip differences.
Thanks. I'm thinking that and springs will work. Dinan or H & R super sport springs?
