I am wanting to replace my stock 16 steelies (2013 rku) with some aftermarket ones I have only found a few aftermarke wheels in 16X7 size. I am running 245/75-16 wildcountry xtx sports 10ply and want to keep them as I like how they ride and feel on the road and for the kind dirt/gravel roads I drive. my question is how will wheels with 4" of backspacing and 0 offset look compared to the stock steelies? I don't like how flat the stock rims look and would like something with a little deeper dish. I am Looking at some Black Rock series 942D's or or 997's. the 942's have a 1700 pound rating and the 997's have 2200 lbs rating. Is 1700 lb enough for a JKU? thanks jeff
