Their only saving grace is that they are not damaged by driving on dry days when its cold outside. Some tires are not to be driven at less then 30 degrees outside air temp...

run summer tires in summer and go with dedicated snow tires in the white stuff (blizzaks perhaps)

It's the big, light, wide, super torqued back end that is the problem. I usually can keep the front pointing but the back end goes full Tokyo drift mode at every bend in the road. I am not driving aggressively at all just trying to creep around my twisty hilly neighborhood.
