What do you run? I'm planning on Nokians for winter but I'm torn between Nordman 7s (because I already run them on the ST) and Hakka R3s. The R3s are really tempting because of those crystals embedded in the rubber acting like tiny studs but I'm not sure they are worth the price difference over the 7s.
For summers I will run the general gmax as-05 which are considered UHP all season but are really just 3 season. I have found them comparable to the Michelin Pilot Sport A/S 3s that came on my ST from factory for roughly $300 cheaper per set.
