Snow traction does not matter to us-we just do not leave the house. I am concerned with wet, cold weather and the slop after the snow is removed. I have 2 tires in mind-Firestone Precision Touring and Avid Envigor. Firestone is too new for many reviews and the Envigor is mixed in snow ratings, but no cold and wet ratings. Any preference or other ideas? Car is a Nissan Rogue, FWD. Thanks.
