Took the Blizzak WS-50's for a test drive around in the snow storm we got here last week.
I tested them after the roads were plowed, but were still snow covered. I was able to pull out from a stop on a steep hill with no problem. Stepped on the throttle a bit to see how it would accelerate. It fished a little and recovered quickly tho, handled turns nicely, while braking they gripped fine also.
Then we got a rain storm later on in the week and melted all the snow. My wife took the Bimmer to work in the rain and she said it hydro-planed like crazy. As compared to the stk Perelli all seasons that came with the car, which were great in the rain. When looking at the treads on the Blizzaks you can see why they are not made to handle the rain well. This is the only complaint I would have about the Blizzaks. Then again, they weren't designed to handle rain. I guess you can't have it all in one tire.
Just a warning to everyone to be extra careful when using these tires in the rain!!!!
