Not very much experience, but bought them last year and absolutely no wear and no problems so far. You'll notice they are heavy in actual weight and, maybe due to more stiffness and less flexibility, my MPG dropped about 5%. Like you, got them for the higher load rating and because Hankook is a South Korean HQ company with plants also in Europe and the U.S. and also, because my extensive Peoples Republic Of China business experience taught not to trust the business practices of that culture when it comes to life dependent products like tires or critical medical devices. One of my biggest fears is a hot weather blowout under a heavy trailer. Oh, they require 110 psi, so check your compressor capacity.
