Get the 37s and decide afterward. I ran 37s on my JTR gasser for 2 years before regearing to 5.13. Daily driving was fine. It's the mountain passes thats a pain. I also started to hit the mountains more regularly in SoCal. I added a small offroad trailer. I trip up the mountain with that trailer did it for me. There's no way in hell I would do that again without regearing.
