Before and after shots. Top is after 2in ready lift. Bottom shot is after putting on some 20 inch American Outlaw Bunker wheels and 275/65/20 Goodyear Duratracs. No rubbing at all. Drives like a Cadillac!

Looks good. What offset on the wheels?

Dude, I'm guessing those tires weren't 100 a piece, and if I'm right then you seriously need to get new rims QUICKLY! You have to understand what happens to tires of that width when put on a 7.5" rim. Yes your rim is 7.5" not 8.5" (if you know this, sorry I sound condescending but other who don't will be reading this). Again directed at no one in particular, the stocke ford rims regardless of model measure 8.5" outside of bead to outside of bead, but the the "real" measurement of a rim is inside to inside. All ford rims's on new models (except for the raptor, although I am not familar with its dimensions) are 7.5" by "X". What happens when you throw a wide tire, like a 12.5" or in my case a 325mm on a narrow rim is that the sidewall at the bottom edge of the tire is sucked inwards. When you do this, especially on tires that have little sidewall, (for this purpose a 35/12.5r20) (tho it gets worse on a "shorter" tire) is that the tire bends to fit the rim it has been installed on, even after airing up. This bend causes the tread to not sit flat, but rather at a curve, which does the dame thing as overinflating your tires by 50-60 psi. In short terms, the tires (mickey thompsons in this case), which should last 50k miles will be worn out after 25k miles. If you buy actual good tires (goodyear wranglers) it will go from 80k miles to 35-40k miles. With the price of tires nowadays, and how cheap nice aftermarket rims are, you are certifiably insane to put too wide of a tire on a rim. Best rule of thumb is 3.5" difference between rim width, and tread width (remember that rims are measured inside the bead), although a 2.5" rule would be a better goal. To the poster, again I apologize if I'm telling you **** you already know.

Actually dude the Platinum and all other Ford factory 20" wheels that came on these trucks measure 20x8.5". The 17" and 18" wheels are only 7.5" wide. His setup is fine. No, he probably won't get maximum mileage out them but he doesn't need to replace his wheels.

Thanks for the concern... In the end I'm not too worried

What's the biggest tire i can use on the 7.5" factory wheel without any issues?

I wouldn't run any bigger than a 285 on a 7.5" if it were me.

I ran 295/65/18 Nitto Trail Grapplers on the stock 18s of 7.5" width. Every tire will have their "Approved rim width" posted. These are listed as 7.5-10.0. Looks like it'll somewhat depend on the actual specs of the tire you're looking at. Obviously people run tires on wheels narrower than the "approved" width and not have any issues (I ran tires on my 4runner on wheels 0.5" less than the "approved" width for the tire). It's really up to you what you're comfortable with
