Right now I just have 33/14.50 swampers. This is a start from scratch build though, I haven't bought tires yet but when I do they will be in 37 radial range. I completely gutted this Jeep, I have to figure out how to run all new wiring. It's got a 383 sbc in it. I am starting to realize what a mess I have myself in as far as wiring. Not sure if I am going to be able to use the factory window door locks controls.
