I am running the 35" MT/R's and I love them. I went from Swampers to Goodyears, bias ply to radial, thornbirds to MT/R's... as you can imagine, I felt like I got a new ride!
I looked at all the tires out there, the Goodyears have a very impressive side wall, and mine are wearing really well, and mine is a DD.
FWIW, I bought mine online at Summit Racing and Walmart can get the MT/R's if you special order them, but then you can get the lifetime balance and rotation, they had a great price too.
I have heard the MT/R's are hard to find right now, but that might only be the 35x12.50's.
Either way you go, they are great tires.
