Our blue 2018 Budget Build truck had BFG KM3 33x12.50" tires on ICON 17x8.5" Compression Wheels with 6mm offsets. We were able to run this wheel and tire combination without trimming with the Falcons on their highest setting. Falcon's tire size recommendations are pretty conservative, but a lot of tire fitment depends on what wheel you're using, specifically its width, offset, and backspacing.
