A good mud tyre will be at best average on road, Muds have large spaces between the tread blocks so you get very little rubber on the road when on tarmac. You've really go to decide. If you want road performance too, then an A/T tyre is the most aggressive you can go for. Compromise the road handling and buy a mud tyre.I guess 'snow' would be the area to compromise on as we get very little of it, so a good on/off-road tyre would be best, albeit with a leaning towards some ability in the snow too!!
