Thanks for info everyone. I'm leaning towards the Dunlop Wintersport 3D, on whatever decent-looking wheels that fit. Preferably 18" staggered, unless the experts say otherwise. Don't think I will be able to avoid driving it in the winter. If some people drive a 911 in the winter, then I should have no problem driving a 1M.
