I bought a used Ford F150 STX 4x4 with these on it. They are a good tire, quiet and long wearing but for me, I have to shift into 4H to get up my dirt driveway. They just don't grip to climb up a loose gravel and dirt driveway at about a 60 degree uphill for about 100 yards. Probably a great flat land tire but not in the mountains. Haven't really gone to far off road with them yet.
