Looks like the consensus on this thread is that the ps4s are an acceptable replacement for the ps2 tires and enhance the drive without inducing other issues.

As an aside I had a set of pss (no star rated tires) on the car for a season and the understeer was horrendous because the side wall stiffness of the non-star rated tire was soooo soft compared to a star rated version of the same tire.

Speaking of sidewalls... the ps2 tire side walls are really stiff. Are the ps4s the same stiffness when performing the finger poke test ????
