I am well aware of the perils of summer tires in the cold. I bought an '05 RX-8 in '05 (which I sold a year ago last Friday, leading to the deal on the '05 Boxster 1 year to the day) that came with summer tires, and was absolutely useless in the cold. I also have two bikes ('97 Triumph Trophy & '10 Ducati Multistrada) that I have been known to ride like I'm perched on tiptoes just above freezing. Pick a dry window between storms, as warm as possible and get it home for the winter. Right now I'm checking the weather hourly, and it seems to be changing hourly
