tire clearance

my 2003 prerunner came stock with 265/70/16 BFG's I just got the 3'' spacer, AAL kit put on and want to upgrade to 285's. i know i can fit the tires highthwise but need to know if 285/75/16 will cause any issues bieng a wider tire.
- im looking into the BFG mud terrain
- moderate offroading

 

Your gonna have to get rid of the front mudflaps(if equipped) and trim the fenderflare to do the pinch weld mod, that size tire will contact frame at full turn and maybe upper control arm when mounted on stock wheels, you'll need either spacers or a wheel with 3.75 backspacing
