I had been planning on replacing my stock rear 19" PS2's and I found a bubble on one of the fronts yesterday so my plans changed. I bought a set about an hour ago of the Hankook Ventus V12 evo K110 in 255/35/19 and 275/35/19. I have these tires on my E46M3 and I like them and they were $425 cheaper for the set than the Pilot Super Sports (after all rebates were taken into account - $60 on the Hankook and $70 on the PSS). The Hankooks got a great review in the
C&D tire test of 2009.
