I work in oilfield construction and I have a couple construction inspectors that spend upwards of 80,00km a year driving on a variety of terrain (highway, gravel, mud, snow/ ice)
One of them has run through 2 sets of 37" Toyo Open County MT's on one Sierra Crew Cab and is now on a set of 35" Open Country MT's on a new sierra crew cab and he really likes them.
Another swore by Interco TRXS STS radials. He claimed they were the best mix of on-road manners, snow & ice handling and off road traction tires that he'd found. He had 35's on an H2.
I've had a set of Pro-Comp MT's (31'a) for about 3 years and I'm pretty happy with them, however I've only had them truly off-roading for maybe 6 or 7 days in the last three years though so I can't really say much about their off-road durability. They make the most noise around 50 km/hr but quiet down some at highway speed. As mentioned by others, they're an MT and aren't a very good winter / ice tire.
Hope that helps
