I currently own an '09 Cadillac CTS-V as my daily driver (my other car being an '09 GT-R). I admit I like what I've heard about the 2013 Shelby GT500, and am actually considering selling my CTS-V and buying the 2013 Shelby GT500 as a replacement daily driver. The problem is, I live in the DC area, and would need at least all-season tires, if nothing else than for driving when temperatures dropped below 40 degrees. I imagine I would occasionally need to drive in light accumulations (<3-4 inches). I was facing the same problem with my CTS-V, but went with a set of Pirelli Sottozero 240 winter tires. Though this last winter was mild and I do not think we had snow, the Pirelli winter tires did noticeably cut down on wheel slip and did increase traction during cold days. What options could I have for the GT500? I would like to go with an all-season tire, or dedicated winter tire. Tirerack doesn't show any options for the 2013 Shelby GT500, other than OEM.
