I just recently put the R/T on my truck. I've always had great luck with the Toyo A/T but wanted something slightly more aggressive this time around.
the first set of tires I put on my truck were LT285/65R20 BFG KO's (not the 2) and I never liked them in snow. I had to use 4wd for winter street driving more than I ever had before. they just packed up and turned to slicks constantly. after about 15k miles they started getting a hum to them. they were still wearing perfectly straight. I checked the balance which wasn't off, played with the pressures a little, and it didn't get any better so I just took them off since I never liked them to begin with.
I replaced those with some Mickey Thompson Baja ATZ P3s I got for a good deal, ran those for a while, but just decided to spend the money on the setup I really wanted, so now I have the Toyo R/Ts in 35x12.50R20 and have been really happy with them so far. the day after I put them on, I drove 200 miles through very wet heavy snow that eventually turned to lighter powder when I got higher into the mountains, never had any major slipping and never needed to use 4wd or lock the diff. and then just the other day I went about 10 miles down and back on a muddy/rocky trail with lots of elevation changes and again, never needed 4wd or the locker and had no traction issues. they've also been quieter than the BFGs were, but they only have a few hundred on them so far. but as of now I'm definitely not disappointed.
can't really speak to the Duratracs, I swore off Goodyear a while ago because their truck tires just never seem to wear well.
