Are you towing with the stock size tires? I am running 285/75s (BFGs) on mine since the truck also sees a bit of off road beach use but it's time for new ones. My OEM size is only a 265/75, since our AS is now on the horizon I am wondering if there are any disadvantages (besides MPG) in staying with the slightly bigger tires, which I really like BTW. I have the diesel so no noticeable loss of power with the 285s.

My 2016 F350 diesel 4x4 double cab came with:
Michelin LTX AT2 LT275/70/R18E
The tires are rotated on each oil change for good reason, as well. The front tires will wear, I say 'cup', if they are not rotated each time. The Tundras I have owned never had this issue, but the Ford will and quickly. Learned that when going in for the first oil change.

Must be an issue with your truck. I got 75,000 miles out of my first set. Rotate every 10k miles, no problems.
Ray, just yesterday I got my new wheels and tires. They are the same size as what you have. I bought a set of Lariat 18" rims which have the proper offset for my truck (they were an available option at the end of production on my chassis) and just got the new tires mounted up. First impression was the ride was slightly rougher than with my 285's but then I gave up almost an inch of side wall with the 275/70s mounted on 18" wheels. The side wall loss from my OEM 265/70s is less than 1/4" however. On the plus side I noticed tighter handling with the stiffer side wall of the 275/70. The tire shop aired them to 60 front and 80 rear which I reduced last night to 55 all the way around (unloaded at this time) so tomorrow I'll take it out again to see if the ride softened. Time will tell.
On the cupping I wonder if you have a shock issue. Although I have an older truck than you do my tires always wear very evenly. I run Bilsteins as well.
