Well the recommended rim width for the tire was 9.5-11" wide. I should have mentioned that earlier but I was just trying to show that you can fit in the outer ranges of the recommended rim width, plus people put 35x12.50 on there stock wheels all the time with a leveling kit. It's literally the most common mod.
