I already have a 2 inch spacer lift and thought I could fit some 285/75 R16 BFG. I put them on and they rub pretty bad. I trimmed the front lip on the bottom of the front bumper but they are still hitting fender liners pretty bad. My question is should I go up to a 3 inch spacer or would wheel spacers help? Also, if I do go to a 3 inch spacer is there anything else I have to worry about as far as shocks or drive train? Thanks.
