Several people have fit 285/70-17's on 4x2's by using a leveling kit and the OEM wheels. I believe the Helo Max 6's are 9 inches wide but I'm not sure of the backspacing. Are you planning on using the 18x9's or 17x9's? Do you know the backspacing? You may be able to fit a 285/70-17 or 285/65-18 (33x11.50) but my guess is it would be a tight fit.
