Completely right! I have considered them and still am. The 285s provide a lesser speed variation than the 35/12.5s though and from everything I've been reading here and elsewhere, the 35/12.5s also slightly rub at full lock on stock suspension which I'd like to try to avoid. Thus why I sought out anyone running either set up to get input and pictures if possible. Plenty of photos of the 35/12.5s but they're usually on Raptors with front springs or perches. I haven't committed myself or my money to one fitment yet and am open to ideas/suggestions - just like those suggestions backed up with pics and data.
The rubbing is only at full lock and it's very, very minor. If you're driving a 2019/2020 truck, you may not have any rubbing at depending on your tire choice and size. I'd recommend running the BFG K02 in a 35x12.50R20. But, there are some 35x11.50R20 options out there that will work as well if you're looking at a narrower tire.
If you're wanting to keep the wheels in the fender, the VR series wheels sit flush with the edge of the fender flare so the only part sticking out will be some tire sidewall.
This is the profile of a stock height 2019 with the VR-601 on a BFG KM3 in a 35x12.50R20. I would not go with the KM3 due to the side biters causing a potential rub issue, but you should be fine with the K02.
If you do have any rubbing, it require only minor trimming to plastic fender well liner on the front end. Roughly a 1" x 2" cut on either side. But again, we could eliminate this with a slightly narrower tire, say a 295/65R20 which would measure out to 35.1" tall and 11.8" wide. That tire would actually be slightly taller than stock.
