What is the max tire size I can put on a factory 2003 Rubicon? What if I install Bushwacker FLAT fender flares? I want to install 265/75/16 = 31.6"x 10.4" on the factory wheels. Would this fit? This would be an increase from the stock 245/75/16 = 30.5"x 9". I can't do any suspension lift. Thanks for any help.
