The problem is always the design of the front suspension the hub carrier arm extends around and over top of the tire on the inside and connects to the upper control arm. This stays fixed in place and does not move, even with a lift. The largest exterior diameter you can get is 265/60R18 without touch the top. But that isn't the immediate problem...the hub carrier arm bends inward toward the tire as it comes around the top so for the wider tires you need to push the rim and tire farther away from the arm using spacers or having rims with a lower offset.
This low offset and wide tire also means you need to get fender flares if your vehicle doesn't already have them. I have the fender flares and running stock rims with 20mm spacer front and 30mm spacer rear.
If you want bigger tires than 265/60R18 then you will need to wait for a company to design a legit suspension lift complete with redesigned control arms, longer axle shafts, brake lines, wider fender flares, and rims with super low offset to completely clear the hub carrier. You would need several inches of lift to clear the wheel well and prevent the tires from rubbing on the front and rear of the wheel well. I doubt anyone will make a legit lift for this truck since it would be a lot of R&D for an almost non-exsistent market. I'm not sure it can even be done because of the front differential design.

So do u think my ET40 8.5x18 rims with a 265/65r18 bfg ko2 would fit it ok with a 1” spacer? On stock suspension so far, I’m looking at a 3” front spacer I found for pretty cheap and programming the aired rear to sit higher
