Mercedes told me I had to buy winter tyres due to all year tyres crabbing at temps below 7c, this combined with their crap 4matic 4 wheel drive. They would store them and fit them each year at Bolton, declined them as they wanted £3.5 k for wheels and tyres!!
Going to be a cold one tonight, was 3c 30mins ago already down to 0c, skies clearing too, can only hope showers reinvigorate, convection will be dying away now.
Will no doubt be better for you with the altitude!! I was working in Oldham Town Centre in winter 2014/15 could be bloody tricky up there, and was just raining here in Worsley.
