Good to see you at SEMA, James!All I can share is a tease, but I've seen, photographed, and driven on the Mastercraft CXT tires in 255/80R17.

Where can I buy a set of 255/86/16 Cooper ST Maxx's online??
I bought the DC Extreme Country tires in this size. I haven't really noticed them being significantly stiffer or harsher than the "C" Duratracs that preceded them. A lot more tread noise for sure, and a big change in torque to the road with the larger diameter. So far I've been using similar pressures to what I used on the Duratracs: 35psi on the road, 22-25 psi on dirt roads (based on wear measurements, I might need to decrease my road pressure.) I haven't been on anything that required lower pressures, although I have been on several difficult roads that lower pressure would've helped quite a bit. Guess I was too lazy to let out more air.Thanks for the update on the ******** Cepek Extreme Country. What pressures are you running on pavement and on dirt? I just sliced a sidewall of my Duratrac (245/75-16 C), so I need to make a tire decision right away. I want skinny 33" tires, but I'm not looking forward to the switch to E range.
I really appreciate your feedback. However, it would be a lot more useful if we know what type of terrain you travel. It is cool that your location is listed as "my truck", but that gives us zero geographical insight into your tire experience. Sierra mud is a lot different than Georgia mud, which is worlds apart from Arizona terrain. And then there is Alaska, Northeast, Northwest, and that is just considering the differences in the USA.Ran 255/85 and 235/85 in ST MAXX, KM2, and bighorn. Ran 235/85 and 265/75 in KO2.
The original KO in a 33x10.5r15 is my all time favorite tire. Since I cannot get a comparable tire in similar dimensions for a 16" rim I'm left with what's been listed in this thread.
My personal opinion regarding both 235 and 255 sizes:
1st : KM2. Superb road and off road performance. Getting roughly 40k-50k out of a set. Balance well And Good weight. Louder than ST MAXX, quieter than Bighorns.
2nd: ST MAXX. Quietest, but still noisy. Lightest. Stiffest sidewall. 45 - 55k miles. Both sets I've had balanced well but had interesting road handling. Tendency to wander and drift. Great in the dirt albeit the load range E. Even with 10 psi on a tacoma I could barely get them to flex.
3rd: Bighorn. Didn't last but 30k miles. Noisy. Balanced well and drove on the road well. Offroad, they were wonderful, almost as good as a KM2.
If money was the deciding factor, ST MAXX every time. I can most often get them for a little over half of what I can get a KM2 for. Otherwise, KM2 hands down.
