So after hemming and hawing, looking for best prices and to meet my needs, I came up with this combo. From the other threads I have read 3.75 backspacing is what I need for my JK with 15" wheels. Also going with 8" even though the 8.5-10 is the tire recommended, again from posts here. The pro comps are also lighter which I like. (I assume these are alloy wheels, not steel, please correct me If Im wrong). As for the tires, going with 35x12.5/15 saves me $100 per tire as the 315x75/16 which I had originally decided. My JK is my DD and I also want to wheel, so these tires seem like the all around best option for me. Any feedback would be greatly appreciated.
