4" and 35's looks sweet and can't be beat for a daily application. I am the minority around here though most will say go big, but having been down that road I say go functional.
Most people can't look at 2 identical trucks 1 with a 4" and 35's and 1 with a 6" and 35's and tell the difference unless they are side by side. If you step up to 37's get the 6".
