I have ran a bunch of different 35x12.50s and I measured the ridge grapplers and they are very much so true to size. I have ran a couple other brands that were significantly smaller than the ridge grapplers.
2021 Trail Boss stock (no leveling kit) with stock wheels on 35x12.50R20 Nitto Ridge Grapplers. ZERO RUB on level ground. Going to level just to get rake out.
Just got my 2021 Trail Boss. Done extensive research through this forum specifically and I appreciate all the help. I was still very hesitant but I had my tire store put 35x12.50R20 Nitto Ridge Grapplers on my truck before I leveled it. On flat ground, there is ZERO rubbing. It can be done, but I am still going to level for the looks.
