I have two German Tyre Tests for premium tyres, 225-45 x 17, scanned from the magazines. Test one had Goodyear Eagle F1 Assymetric from Hankook Ventus V12 and Bridgestone Potenza RE050a. Test two, same size, had Goodyear and Hankook first and second, with the Pirelli P Zero third.

They were very thorough tests (I speak German), and I would go for the Hankook as the top three were very, very close but the Hankook is much cheaper.
