I went wheeling with a friend over the weekend who had a brand new set of the new MTR's and I was overall not impressed at all in the snow. Hes locked front and rear and had problems going anywhere that wasnt tracked out. I drove the truck and it just wouldnt cut out of ruts and it seemed to struggle when breaking trail.
compareably in all the same places I had 0 problems in my truck with the original Bfg Mud Terrains.
Personally I wouldnt buy a set of the new MTR's.
