This is the tread of my latest winter tires - namely the Pirellis winter sottozero . Note the none symetrical tread pattern. Winter tires reduce my insurance rates.Less spinning out on corners when I hit the gas. Way better than the symetrical Blizzaks.
Won't be putting on the Michelin pilot sport a/s until late April. They were not that good in snow/ice last fall. Feel better with snow tires on.....be warned!
