Long time skier in the Canadian Rockies and these are the worst tires I have ever used. I feel taken by Mercedes for selling them to me. Probably only good for city winter conditions. On the highway there is very poor connection to the road in true winter conditions and very little comfort that the vehicle will stay on the road. I have been driving on these roads my whole life and these tires are bad. Actually sent them back to the shop to see if they are defective because these are not good on highway ice.
