Trxus are by far my favorite. The aggressive tread is great for mud and rocks, but the biggest seller for me is the wet road handling. All the siping per lug is a big plus when compared to other MT's that may have one sipe per lug, but usually not any at all. The Trxus are heavy, and a little more difficult to balance, but they balance better on an aluminum rim in most cases. I've never cared much for directional tires. They seemed to want to wander more IMHO, and if you need a spare, it will only face the same direction on one side of the vehicle, so hope you get a flat on that side.
I have 31" Trxus MT's on the wife's ZJ right now. I had 34's on my XJ, but going up to 35's real soon, then 37's next summer when I finish my full widths. My first set of 34's I got almost 50,000 miles out of them and kept two for spares since they weren't to the wear bars yet.
