I've had a set of Winter 909's (discontinued) and loved them. They also survived summer* driving without the typical snow tire wear and wallowiness(sp).
Alex.
*I was going to get rid of the car, didn't want to buy new summer tires for it, ended up keeping the car an extra two years and still was pleased with the performance of the 909 in the winter. By contrast, the BFG Winter Slalom is the biggest peice of crap when the temperature warms up, I didn't even bother to burn them off as a final hurah.
