The Bridgestone Blizzard neither gripped as well or lasted as well as my other winter tires. Particularly lacked grip very badly on wet roads which became greasy after night frost had thawed in the day. I think what happened is it slipped more than my other tires and because of that it actually became polished when on the front of my front wheel drive vectra estate cdti 150 where it was balanced by a Hankook winter due to the frequent slipping of the Bridgestone. It was so bad that I swapped the Nokians I had on the back. Once I had put the Nokians on the front I had great grip again, it seems that on this car I need really good grippy tires on the front and the rears are less important, which is not consistent with other advice I have had to put best tires on the back. That advice would seem sensible for a rear wheel drive car. I think a critical thing is to have balanced tires on each side to avoid one slipping more and becoming polished at times when the roads are extra greasy and slippery. This Bridgestone also wore a lot more quickly than the others, probably due to the regular spinning due to it not coping compared to the other tires.
