I've run Continentals for the last ten years. A little pricey, but worth it. A few months ago, got some new ones - the sidewall says "duraskin - max grip silica" & they're supposed to be good for wet weather. They're the best tires I've ever owned. I easily have 700 miles on them & the little rubber strip in the middle of a new tire (does it even have a name?) hasn't worn off the front tire!

They aren't knobbies, but they do have a tread pattern. I road over some icy bridges this morning - no problem. I can't tell you about snow - isn't that that white stuff that falls from the sky in the winter? I've seen it on TV....
