I have 31's with the 6" pocket flares, but I have just enough backspacing that the tires are about 1/2 inch wider than the flare. I have never seen 4 1/2 inch pocket flares. Where have you seen them for sale?
Dake, I love your set up! It is exactly the look I am after. I have the 4.75 Bushwacker Pocket Style flares also and I need to know what suspension lift and or body lift you have in addition to your rim and tire size.
