BFG 285's will rub on a 2WD at full lock w/out leveling pucks.
Are you talking 285/70 or 285/75 R 17s? For height purposes, the 285/70 is 32. 7" tall, and slightly narrower than the 285/75, which is 33. 83" tall. I believe both will rub at full lock on the plastic inner liner. There is no size listed inbetween in an 8 or 10 ply tire in a 17" rim diameter. Try the 285/70 and just don't turn all the way... ...
What about with a leveling kit? Or are the 285 still too wide?
