Winter and Cyclocross tyres / tires

And while I'm here - just bought a Tricross single for winter use, which came fitted with Michelin Mud 2's - any use whatsoever on tarmac in wet/wintry conditions?

Been thinking about going for Vittoria Rands which seem to have pretty good puncture protection, lighter than MP's and fairly useful in most conditions - oh and cheapish too.

I'd swap them out for those rando's, and save them for dirty fun. They will be wasted on the road, a bit uncomfortable, and will ear down pretty quickly.
