Well, I ordered the 285/70/17 Duratracs. They are going on my current level 8 tracker rims with 4.5" backspacing. Been real happy with the rims. The 285/70 will stick out just a hair from the fenders and I'm think the "D" load rating compared the the "E" of the Nitto's will help even out the ride. The Duratracs are slightly lighter. I was very happy with my earlier 33x12.5 Duratracs on 15" rims, but I wanted to move away from 15" rims. I'll post some before/After pics next week and update this with the ride difference.
