Ive got a 99 Limited 4X4, stock is 265/70/16 and picked up some wheels that are running 305/70/16, would that require spacers and if so where is a good place to buy some cheap but good ones, thanks!
With no lift, you will be doing a fair amount of cutting and pounding.
What backspacing are the wheels? Width too?
The wider the wheel and the less the backspacing (including spacers) will push the tires outward which will cause the tires (fronts) to have a larger arc when turning (steering). This larger arc will require more cutting. You will probably also run the upper fender lip when stuffing tires.
My friend that is running 305s has ~4"+ suspension lift in front and ~6" in back. He is also running a 1.5" body lift. The body lift will keep the tires from rubbing at full stuff (on the tops of the fenders). He has also cut the rear bottoms of his front fenders (~2" and the bottom edge tapering to the stock edge up about 6"-8".
Direct bolt on with little to no rubbing will be 265/75-16.
