I'm running 31x10.5x15 Hankook Dyna Pro ATm on my '91 yj with 2" body lift, but pretty much stock otherwise. I don't do real hard core off road, but I've been places that one of my ATV friends was surprised that I got to. I haven't used them in mud, I don't think they would be good for that, but I've run them in up to a foot of snow and they do excellent when in 4x4. They run on the road as well as any all terrain tire I've had before, and I was very surprized/pleased with their off road performance.
I live in Winnemucca, NV. and a lot of the mine trucks around here run this tire.
Today, we need a nation of Minutemen, citizens who are not only prepared to take arms, but citizens who regard the preservation of freedom as the basic purpose of their daily life and who are willing to consciously work and sacrifice for that freedom. — John F. Kennedy
