Well my buddy fit 215/60's on stock 4" wide bus rims but it looked like ass
The taller the tire is, the better a wide tire will look/fit on a narrow wheel. Will it be lowered? A 165 in the front will be too tall if you plan on lowering it. Also, I don't think a 185 will work with a 165 up front (assuming you want a taller tire in the back), because a 185/65 is shorter, a 185/70 is about the same height (and expensive), and that's about all that's avaliable! Same deal with 195's... so if you want some width and height go 205/65 or 70
