I would advise passing on the MT/R's. Hands down a horrible tire. Tough to balance. Don't hook up well, at least here in TN. The whole thing was not a pleasant experience. I am running Toyo's right now and they have been great. 2 of them do not require weights at all.
I would be surprised if you didn't like the Patagonia's. Everyone I have spoke to absolutely loves them.
Really? Many of my local friends run the MT/Rs from 35s up to 42s and they seem to work great here in Ohio. A good friend of mine is running them in a 42 on his LJ with raceline beadlocks and can run 70+ down the highway and never balanced them...
I got the Cooper Sst pro on mine been good tire so far got about 15000.00 miles on them so far still have half tread on them. They stay balanced.
My STT Pros have around 30k on them and are getting to their last leg, which is why I am looking for new tires. I have really liked them, though I have sliced two sidewalls with one resulting in a full puncture.
I originally looked into the MTZ P3 before I settled on the STT Pros, I liked them as well, settled with Cooper because they were made in Ohio.
Ran them around 20psi that day. Hindsight is 20/20, they probably would have performed even better if I was aired down more.
I usually air down between 10-12PSI w/out beadlocks when wheeling, so I'm sure they would be pretty malable. I plan on getting beadlocks when I buy tires if not before as I am tired of breaking beads and will be dropping to 5PSI from then on.
