I ran a set of STS 33x12.5 for about 20K miles. 80MPH they were fine.
Great on sand and rocks. Not so much in mud.
My problem is that the sipes are shallower in the center of the tire. By 20K miles wet traction was almost non-existent.
Also, to keep tread wear even across the tread, you have to run them at 20 pounds for daily driving.
Now, the TRXUS MT is another story. I am on my third set. I love them. Not a high mileage wear tire either. But great on and off road. The best on road wet traction of any mus terrain tire. Great in New England snow, rocks, mus and sand. This was my first NC winter. I was stunned by how little it takes to shut everything down. Ha!
