Ah right, duh, the truck weighs something. That was the stupidest comment I’ve ever left haha.
Is Offroading in a SuperDuty Really That Bad?

Yep, you are exactly right! I’ll stick with E loads, just might have to change tires. Will see, will call Falkena nd discount tire on Tuesday. At the very least, valuable lesson learned: don’t trust discount tire’s website specs haha.

I think your truck looks great with the 35's. Honestly from the factory, the HD trucks that come with 17' wheels look under tired to me.
I'm running 35x10.5r20's on my factory wheels.
I never noticed a difference in noise. MPG? Probably worse? I had the tires put on when the truck was pretty new so can't compare.
I'm getting about 20 MPG now and I'm fine with that,
Larger diameter tires will also give you a little extra ground clearance as well.
I went with Toyo AT3's in load range E.
(No D available in that size and I wanted something a little more stout than the factory P rated tires for trailer towing duties.)
Nice!
For those that care: I spoke with Discount Tire managers today, as well as an Engineer at Falken.
Discount tire does not base tires off of the manufacturer's requirements (this is bizarre) but rather the vehicle manufacturer. So Ford says a 35x12.50 can fit on their 7.5 wide steel wheels. Falken however, said that the tires were dangerous and need to be replaced immediately.
Nonetheless, I'm going to forego an inch and change to the same tire in 285/75/17 which is 34.1 inches in diameter rather than 35.1. Which is fine.

BS on both. I'm pretty sure that Ford doesn't spec 35x12.5r17 on anything, and DT going by Ford (with rim not specified) makes zero sense...
Never seen a 35x12.5r17 tire that says a 7.5" rim is ok. 8" is the minimum. Note that "35x12.5" tires are always measured on a 10" wide rim, so they aren't really very wide since most people put them on a 8-9". Figure about .4" of tire width per 1" of rim width.
285/75r17 will be fine.

I believe the Raptors (both F150 and Bronco) come with 35x12.5x17 (or 315/70/17). But the rims are 8.5” wide. Fairly certain they do not come on any factory rim with 7” width.

I *think* Super Duty Tremors come with 35's as well. Maybe on an 18" rim though?

This is correct. Super duties come with 35s on an 18x8" rim.

Yes, 18x8

And also correct they come 285’s, which are ~11.5”.
So I’m not sure why Ford would unnecessarily put out a statement that 7” rim would work. I’m guessing it was hearsay from a friend’s cousin’s second nephew who worked as a parts runner at a Ford dealership.
Buddha.
Finally in expo white.
This is the reason I went from 17’s to 18’s on my 2500. I like the look of the 17’s but you cant find many skinny 35’s on 17’s. 18’s was the easiest way to fit narrow 35’s (285/75r18) on my stock Chevy with the small wheel wells.
