255 tire on a 9 inch rim

[hearno]

When I upgrade my wheels, I really wanted to pick up a set of Konig 6 shooters in bronze. I like skinny tires tho and I planned to get a 255/80 as an upgrade from my current 255/75. The problem is, BFG recommends an 8.5 inch wide rim max for the tire I'll be running. I've googled and found a Tacoma with a 255 tire on a 9 inch rim and it looks ok. Should I be concerned about the .5 inch variance from the recommendation or put them on and call it good?
