Thank you, I'm going with the same width/aspect ratio tire in the back as you, if not a little taller. I'm running a 285/50-18 in the back right now, which is 29.5" tall and a 255/50-18 in the front, which is 28" tall, on stock wheels. I was checking to see how much room you have between the top outside edge of the front and rear tires and the lip of the fender well. I want to try keeping the fender wells as full as I have them right now. Thank you again.
