A little late to the thread here, let me chime in with a product that has served me extraordinarily well over the years. It is the BigO XT. It's kind of a cross between an AT and MT. Anyway, I can't say I'm a fan of the BigO
comporate entity especially its sales folks, in fact quite the opposite, but I have had amazing luck with this product.
It is studdable, without siping performs amazing in snow & ice, and has taken a serious beating by countless offroad trips. The last pair of XTs I had for 6 years and about 60k miles, and still a lot of lug left and are on my 40 series now. I have heard folks really badmouth these tires because of the sidewall, but I'm the only one I know that has ever run them; I never had a puncture and those tires ate many hundreds of miles of rock on their sides, not once in 60k miles had a flat or even a small leak? Lucky? Maybe.
I bought them because by default the XT is a free fix & replacement for the life of the tire, yet never had to employ it.
Anyway, I am now on my second set with only 3k miles in. If you can find a decent store, I by all means recommend you at least take a look at them.
Another tire that I don't think you can beat for your $ is the Dunlop Mud Rover:
