Yet another newb question here, I tried to fit 285/75/16 on my sons 91 K1500 yesterday and they rubbed sick. The shop told me it was becase i have to much backspacing on my wheels 4" BS and -12 offset. I called a local off road shop and the guy recommeded a Zone 5-7 inch lift. Anyone have any input on how that will look with 285/75/16's? Pics would be very helpful.
