You know Kumho makes a Road Venture M/T KL71 that I just got on my Chevy (37x13.50R20) and they look sweet and everyone I talked to about them said they were worlds better than any other tire they have ever ran....
I trimmed the front valance about two inches or so and did some minor trimming on the rear of the inner fender plastic. The t- bars are cranked up a bit also. They still rub a little on a full lock turn. I need to zip tie tha parkbrake cable back. It doesn't rub enough for to worry about.
When tying back the park brake cable and fender liner, you may want to use some type of wire ties rather than the plastic ones. Plastic ties can stretch and eventually break.
So far these STT's are the best M/T's I've run. I've run Goodyear MT/R's {shortly},Toyo M/T's, BFG M/T's,Pro Comp M/T's {shortly},and been around X-Terrains and Maxxis Bighorns.
I'll probably put BFG KM2's on my dually ):h and give them a shot
