According to tests made by a German magazine (Auto Motor und Sport), these tires came out on top:
1 - Pirelli P Zero Nero (not M+S), 194 pts (99 pts on wet, 95 pts on dry)
2 - Dunlop SP Sport Maxx, 191 pts (95 - 96)
3 - Michelin Pilot Sport PS2, 187 pts (91 - 96)
4 - Goodyear Eagle F1 GS-D3, 180 pts (89 - 91)
5 - Uniroyal Rain Sport 1, 179 pts (95 - 84) Note: not sold in NA
6 - Falken FK 451, 176 pts (83 - 93) Note: it got 10/10 pts in both Straight and Curved aquaplaning
All tires were 225/47/17 (of course!). These tests include wet and dry, braking, handling, roll resistance, noise, hydroplaning and so on. They are very, very professional tests (tons of sensors, many sets of tires)
In another test (Another German magazine) the Flaken 451 came 2nd, but the other tires tested were older models (not the ones here) but it did beat Toyo T1-S and the old Pilot Sport. The winner on that test was the Dunlop SP Sport 9000.
Personally, I'd love to try that new Sport Maxx (it's the offical tire of the German DTM series). But in the category "best bang for the buck", the Falken 451 is also very interesting...
