If you do a quick search there's a good amount of threads that have the information, including pictures, you're looking for. I think if you run a 2" spacer lift you're looking at 295/70 (34). Some have even put 35"s on without any issues. My personnel opinion is I like the look of the 34's better with the 2" spacer then the 35's. FYI, the FX4 has about a 4" stock rake.I ordered a 2021 XLT 302a FX4 sport with the 18" gloss black wheels.
Id like to put a 1.5-2" level on it with as big a tire that will fit without any rubbing.
Anyone have an idea what the max tire size would be? I was thinking of trying 275 85 R18s...
Yeah I may just opt out of the FX4 and get a small lift. I don't like the look of that big of a rake.This is a FX4 with a 2.25" spacer lift and 35's. You can see how much rake is still left in the truck with the 2.25.
