I'm now running wheels with 3.75 backspacing and 33x12.5x15 tires on a 3" Suspension lift. That backspacing will push the wheels out to prevent rubbing. Also needed that backspacing to keep the rear tires from rubbing the spring perch. But if your rubbing upper part of wheel wells then wheel spacers won't fix that. You will need a BL or SL.
