Couldn't decide on PSS or AS3, went with AS3 as I live where at times when is does get cold but never snow ice on the road, North Georgia Mountains. Gets below 40 of course but I will take my chances. On way to work with AS3 hit the curves as usual and wow was it scary, seemed to flop/roll over when pushed into curves. My original equip were better handling. Good ride but nothing to write home about. Having the PSS put on Monday.

The PSS isn't going to be as stiff as a runflat either. The Roadster S requires 38 psi and my installer set the A/S 3's at 34. Correcting the pressure made a significant difference. You also have mold release on any new tire so the grip improves after 300-500 miles.
