I have been running the Bridgestone Duelers 255/55/18's for almost 2 years. Here in Oklahoma we get it all. Huge thunderstorms with torrential rains, flash floods all the way to the most recent ice storm that left us with 6 inches of solid ice on all the roads. I have to say that the Duelers have really held their own on all the slippery stuff. In rain they hold the road like a champ. In snow they are the best non studded tires I have ever driven on. Even when the conditions get slushy my X5 is still rock solid even in the turns and up the hills. As far as driving on 6 inches of solid ice I firmly believe that no non studded tire can hold well in those conditions. However I did drive 25 miles each way to work on that ice for a week with no incident. I drove VERY SLOWLY I have to admit and used mostly engine braking. I have to say the Duelers are much much better in wet and snow conditions compared to the stock Michelins they replaced. In fact they rock in snow and water. They inspire confidence and feel solid and safe. On dry roads I can't really tell the difference between the Bridgestones and the Michelins to be completely honest. The Bridgestones might be a little quieter, but they both hold the road pretty well overall when its dry and level. Hope this helps.
