I've got the factory (a new set) Dueler H/T's on the VX i just bought, and I'm sold!

We're having a bit of snow (turning to ice & freezing rain) in Portland and they've been flawless. Great stopping & starting and good lateral grip even on this stuff.

I know you're looking for more of an open, mud tyre but if you're looking at brands, I'm pretty happy with the Bridgestones. I don't like most of their tyres, so coming from me this is a big compliment.

If you can find a Michelin in a size you want, they're always good too, other than they wear kind of fast.

Good Luck.
