I've been running 255/80/17s on whats now commonly known as the bronco black diamond wheels. No issues other than a tendency for the rear to get light in very wet conditions while trying to corner fast. So no real issues haha!
I got mine early on so there wasn't many options available.
I have the tailgate damper which is nice but there have been sometimes when I was in a hurry and I thought it was too slow. Other than that it's really nice. I have a video on mrtrucktv on YouTube of the install.
I'm looking to buy the black 17in steel spare wheels found on fx4 models. I'm trying to find 4, with or without tires is ok. I'm located near Royston GA
