Bought these tires to replace PS2's due to their similar tread pattern, high rating from those who have used them and the favorable price point compared to the PS2's. So far they appear to be every bit as good as the PS2's. I do not track my car but in normal and spirited in town and highway driving they will not disappoint. I have not had them out in the rain yet but expect them to be the equal of the PS2's. While they generally seem to get a higher overall rating than the PS2's my experience has been they are every bit as good as the excellent PS2's on the road not necessarily better. I believe their lower cost and their extra 2/32 of tread depth give you more value and longer tread life than the PS2's which accounts for their higher ratings. Great tires at a great price that I would highlly recommend for Porsche owners.
