First off, no way would I buy these tires again. They are on the verge of being completely unsafe any time the temperature is in single figures or lower.
Grip is poor in cool or wet conditions, causing understear (I have some older tires of a different make on the rear axle). If you follow another car around a roundabout, matching their speed you could slide quite easily.
If it snows, forget it! My Bridgestones are on the front axle, on a front wheel drive car. I recently got stuck in a carpark which was at an angle of much less than 5 degrees from the horizontal with about an inch of snow on the ground. It took one average sized man to push me out. Hopefully that demostrates how poor the grip is. Furthermore, my previous tires (some worn Westlakes which had a towards-illegal depth of tread) in conjunction with the car was beating many part time 4x4's up snowy inclines, around corners etc.
The dry weather grip is ok-not noticably lacking or amazing, but then I don't exactly push to the limit. Fuel economy has not changed by more than a few mpg up or down in comparison to the previous tires. After around 4000 miles the tires have not worn excessively.
