Wheels and Tires:
I wanted 37's, I dont need 37's, but I really really wanted them. All reports were that they fit pretty well on the 2018 trucks, but no one (that I knew of at the time) had been down this road with a 2019. I will tell you they fit, and I did ZERO plastic trimming. I did use a heat gun to "push" the plastic at the rear of the front wheel well back, but that is it. Not trimming away plastic is important to me in the salt belt, so this was really ideal.
Was able to sell the stock wheels and tires for what I thought a good price was, so that offset some of the "hit" on this upgrade.
So far, I have not experienced any rubbing with my combo, but I still need to really flex it hard to be sure.
The new 8 speed transmission has a lower 1st gear then the previous 6 speed, and I dont really notice a difference around town. I have not towed anything with this combo yet, but so far, I am really pleased. I may regear in the future, but for now, it seems to be working pretty well with the stock 4.10's
The wheels are AEV wheels (17x8.5, +27mm offset), and the tires are 37x12.5r17 Falken AT3W's. So far, I am a big fan of this tire choice, they are quiet, and I read only good things about their snow traction. My FJ had BFG K02's on it, and these are quieter, and I believe will wear better. Snow traction is important for winter hunting trips, so hopefully I made the right choice!
