I like in Northern New England, and worry about winter weather when it comes to my tires. Normal tires I worry about how it interacts with things like snow, let alone these; 'normal' all weather tires tend to pack snow in the threads and make it seem like you're driving on bald tires, so I need to research all weather tires based on winter weather performance. When I'm dealing with cars, safety is number one on my priority and drive-ability is number two. While efficiency is important, its much lower on my priority list than most things.
