For an offroad tire of any type to be used in all snow conditions (icy hardpack to deep offroad), I do not think the trxus MT can be beat, for these reasons:
- Soft compound that does not freeze even at very low temps;
- Large center lug siping that is perpendicular to the tread;
- A curved outer lug design that only keeps the inner 10" of tread in regular contact at highway PSI. This is the tightly packed and highly siped portion of the tread and gives the benefit of a narrow tire tread contact patch without losing the large TSL outer lug for deep (2 feet plus) conditions paddling.
- Large open center channel that supports excellent lateral traction and predictable easing to the limits.
I always look forward to snow because my 80 is so fun to drive in winter weather. My comments do not include black ice (freezing rain) as we really don't have that in Colorado and no offroad tire will handle black ice well.
The downsides are:
- A soft compound limits treadlife. Anybody getting 40K is taking them down pretty far.
- You have to care for balancing, although I've had no issues and I am about halfway into useful life (2 years and about 13K miles).
- This much siping can lead to chunking. I have had no serious issues with some pretty good rock crawling, but an every week wheeler might see more. Of course, Toyo MT's aren't going to hold up forever as they get rounded and dinged from rock abuse either.
I have abused my sidewalls big time, and they don't show any issues, but that's not a statistically relevant data pool.
I'd ask Nakman - he ran my old 33" trxus (to the statement that going from BFG AT's to trxus MT's was like being a cat and discovering you have claws

) and is now running 35" Toyos. I've been waiting for his opinion as somebody who has actually run both.
There is no question to me that the design of the Toyo delivering AT type roundness on the highway along with its offroad performance and relatively good reviews in the snow ("as good as a BFG AT") makes it a player. It has greater tread depth in a 35" size, probably has a better treadlife, is more likely to avoid day one out-of-round issues, and probably is more likely to be backed by the manufacturer if you have an issue.
I don't like the extra weight and the idea of a flat contact patch across an 13.5" wide tire, but for a guy praising Interco that's splitting hairs at best
