I've got MT/R Kevlars on my 40, and Duratracs on my 100. I am thoroughly impressed with both tires. If you're going to stay with a 285/75r16, I'd go with the Duratracs. Mine are load range E (10 ply), while my MT/R-K's are load range D (8 ply). I've sufficiently stabbed both sidewalls, and have some good road miles on both sets. Either is a good choice, but I would try the Duratracs first.
