Heres a pic of mine with a 6” lift, 35’s. It’s actually loaded down in the back in this pic so really sits higher then this too normally . Me personally I’d go for a 6” lift because the price difference isn’t much and it looks a lot better . Most lifts are going to require 20” wheels or bigger to clear the knuckles btw. With a 4” lift it’s a lot of money to not get a lot of lift.
As far as wheel width , a 9” zero offset is going to look tall and skinny on a lifted truck. That’ll pretty much stick out same width as fender . A positive offset definitely would look too narrow on a lifted truck unless you run 2” wheel spacers then maybe look ok but those things are hard on your truck . I’d go with least a 10” wide wheel . I’m running 20x12’s -44 offset if your going for the tall and wide . Looks more aggressive .
