Funnet en god review av dekkene her:

I have had opportunities to use these tires in rain, snow and rocks since my last post. I am very happy with them in all of these scenarios. I have had them in mud, but hardly anything that would qualify as a substantial test. (and that is fortunate, because I dislike mud driving). I have been really impressed with these tires on the "rock crawling" type of trails. They "hook up" and stick very well for my truck. I was also really happy with them in the snow. I managed to drive some roads and trails where I broke the first tracks, and they did very well.
As for pressures:
I run 34-35 psi on the street. (With my old 32" BFG A/T's I would run them at 32 psi.) Since the lugs on the MTR's and STT's have a bit more resistance (and consequently worse fuel economy) I run them at just a bit higher pressure than an A/T tire.
For trail use, I run anywhere from 20-24 psi for mild trails depending on the surface conditions. For very technical trails on rocks and dirt, or the occassional severely corrugated (or "washboard") roads, I will go down to 17-18 psi. For sand or mud, if 18 psi is not performing well enough, I will go down to 12-14 psi but it is rare that I am in those conditions.
Keep in mind this is for a 32x11.5x15, Load Range "C" tire on a truck weighing in the low to mid-5,000 lbs. range with even weight distribution from front to back. - bajataco.com
