Lifted, need tire and rim recommendation

Hey everyone, so I did the 3 inch spacer/leveling kit, and I'm ready to do rims and tires, i am just going to do cheap black steel rims, my question is what would be the best size for rims and tires? any examples from any of you? I want to go bigger.

 

37s for sure. There is an entire wheel tire forum that you can browse for days. I'd check there fist, 100% this question has been answered already multiple times.

 

Most 16" steel wheels won't fit, pro comp makes one but it can be hard to get. 17" wheels will need to be 9" wide so they'll stick out from the fenders requiring more trimming to get the tires to clear.
285/75-16 or 285/70-17 are very popular, and pretty much the biggest tire you can fit with some moderate trimming to clear, possibly also requiring the CMC (cab mount chop).
