I was also running a 255/55/18 up front with 305/45/18 in the rear. The 255/55 fits perfect on a 8" wheel and ~3" drop on a GMT800. I am in the process of lowering mine and extra inch up front and went with a 265/50 for a slightly wider and shorter tire. It's about as wide as I would go on a 8" wheel and 28" tire height. Many moons ago, I ran a 285/50/18 on an 8.5" wheel with a 2/4 drop and they looked and fit great. I dug up an old pic for you...

You've had some tires on that thing! Is that truck original owner? Those headlights look clean enough to eat off of. My Centerline Galaxies are an 18x8.5 wheel, and measure 9" lip to lip. Choosing tires is tough! The advantage of a 31" or 31.5" tire is that they fill the wheel well up more and the ride is a bit better. Whereas, a 30" or 30.5" tire will shorten my final drive a smidge and lower the truck even more. Ultimately, I need to choose a tire that doesn't bulge excessively, and is a commonly available size. There isn't much available in 285/55/18. I wish tire shops had mock-up sets laying around... A little more or less sidewall can make the difference between a truck popping and another run of the mill truck with rims. My wheels come back from repair/ polishing later this week so I've got a couple days to decide. Here is the truck with bald down to the cords 285/60/18 that the wheels came with (couldn't mount the rears as one of the tires didn't hold air):
I photoshopped 2 more Galaxies on top of my stock 31.5" 265/70/17's:
