Compared to the stock Pirelli Scorpion Zero Asimmetrico tires, the Michelin Pilot Sport A/S 3+ in 255/45R20 size are better in every way. Most notably the ride comfort and road noise are excellent. Wet and dry traction are much improved over the Pirelli. There are not very many choices of tires in this size but regardless I am completely satisfied with these tires. I will most likely be putting them on my Saab 9-3 convertible in the fall.
