Let me make it easy for you... Get Goodyear F1 GS-D3's. I only here excellent reviews of these tires from many sources, including a Cadillac CTS-V forum. Many mention that they can't tell the difference between driving in the dry, and driving in the wet, they are that good. For an all-round, ultra-high performance tire, you can't go wrong. They are a decent price as well! Good luck in your search for tires...I know when my tires are ready to be changed, I'll be getting the Goodyear's!
