Anyone hear any rumors about what the winter tires will do to range? I remember reading somewhere that the 21" wheels come with a 5% reduction in range, but can't seem to find any comparable info on the Pirelli's.
Last winter I was loaned a set of Pirelli tires for my Roadster. At freezing temperatures I had about a 10% loss in range. I had the same loss at freezing temperatures with my summer street tires. (I once hit freezing temperatures (unplanned) while running A048 and it was much worse than that.)
