I have studded Nokian 8 tires on one Camry, and Bizzak WS90 tire on another Camry. We have had every snow/ice condition possible lately. The studded tires work great for some conditions, like wet ice and fresh wet snow but the traction is unpredictable at times, and if you overdrive them on hard polished ice they will just skate when you would expect them to grip. For all around winter driving I have always been happy with how much more predictable the Blizzak's are, plus much quieter. I've had Blizzak tires on all of my vehicles in the winter since 1996, and have been disappointed when I tried something different 3 times. The X-ice tires on my Tahoe PPV have been very disappointing.
