I have now driven back and done over 2000 miles. They have been great in snow and also in the very wet condition in the past few weeks in the UK. They are not noticeably noisy, perhaps 5% less efficient than my last summer tires, and appear very stable. I expect them on the evidence of a few warmer days before going to the Alps that they may be slightly less precise in warmer weather, but the trade off is worthwhile, given the stability they have showed in difficult driving condition
Regardless as to how good the tires are, any tire will have a limit on snow, so even though I recommend these tires, you still need to drive with caution, but they provide the edge required when encountering snow and wet in winter conditions
