I bought a set of four Blizzak tires from Tire Rack. The tires are totally ineffective in the snow. They slide and slip and don't provide as much traction as my regular all season tires. I had Bizzack WS60's last year and they were just fine. It is my understanding that Bridgestone reconfigured the W60S's and came out with WS70's. I wish I had left my all season tires on because the WS70's are a disaster. What is even worse is that fact that Tire Rack won't help me with the purchase. They just say there is nothing they can do which is hard to understand because they say they are revolutionizing tire buying. What a joke! Any retail dealer would take the tires back and put on another set. Tire Rack avoids my calls and in some cases won't even return my calls. My guess it that Tire rack is just a shill for Bridgestone because I wrote a negative review of the tires and they won't even put it on their website. Very disappointing behavior for a merchant.
