My dad ran them on his power wagon and jeeps (17"). They performed excellent on the jeeps but only so-so on the heavier wagon. The punctures, mostly sidewall, is the draw back. We had four flats, 3 sidewall and 1 in-between the lugs, in 6 weeks of offroading. The punctures were from rotted iron wood tree stumps hidden under the sand.
The environment might have had something to do with our tire failures. We working in the CA desert in summer with 114 degree air temperature. No telling how hot the ground was and how hot the tire was from normal friction. Add those three aspects together and no telling how hot the tire was.
Toyo Open Country M/T is the way to go on heavier vehicles. I have them in 20" size on a 2500HD Duramax. Drove through similar terrain, as the power wagon did with Hankooks, with no punctures.
