Your not going to have a flat wheel with 12s, the section on the 335 is 13 1/2, so you have a good 3/4 buldge which is the way I like it. When you go to 13s, the rim is basically as wide as the tire. Anything less then 12s will actually pull the corners of the tread up and create a high spot in the center of the tire.
