While I had heard over the years that Blizzak tires were really awesome in the winter my experience with them so far has been pretty poor.
One icy roads, and in snow, they perform quite well and you'd expect this from a winter tire.
In slightly warmer temperatures where the road is wet and it rains heavily the tires are EXTREMELY poor for handling. It doesn't take much throttle on my car to spin the back out when it's wet outside with these tires.
They might be OK for a normal economy car, but for a high performance sports car they're very poor. I should've sprung another $400 total and just got performance winter tires, but lesson learned. Will not buy these again.
