ok, the Kumho Supra 712s and Yokohama ES100s are horrible tires...

I'm currently running Kumho Ecsta MXs (Tire Rack calls them extreme performance tires). You simply cannot beat the MX's S-tires for the money. I'm waiting for them to go bald so that I can buy a set of Potenza SO-3s, Michelin Pilot Sports, or PS2s.

For the track, I'll be running Hoosier A3S05. (I was thinking about the Michelin Pilot Cups, but I don't like how they're so tire pressure sensitive.)
