I just removed a set of Hankook's from my 3/4 ton Chevy Diesel pickup. They had about 50K miles on them and about 1/3 of the tread left, but they were an "off-road" type tire and I needed more open tread style for pulling in muddy conditions. I was happy with them UNTIL we took them off. The passenger side steer tire had two place on the inside bead/sidewall that had seperated, were bulging and looked like they were about to blow. as a result, the steel belts in the tire had eroded the rim of the wheel enough that it required replacement. Needless to say, Hankooks are no longer on my list of tires to consider.
