We had Eagle LS tires on Steve. They had little grip below 50* or if it was damp and if there was any snow on the ground they were about as grippy as skis.
The Eagle tires on the Cobra were great in anything, but they were a full on race tire. Of course on a gravel road it sounded like you were in a hail storm because the rubber was so soft the gravel would stick to them. They also tramlined terribly if there were grooves in the road.
If there is much snow we just take the truck with Blizzaks on it. Supposed to get 1-10 inches this weekend. I love weather people.
