My door says 35 all round but it makes for a harsh ride.
275/55-20
Dropped to 32 and it rides much better.
Winter gas, mileage is horrible.

I also have the same wheel/tire setup as the OP, on a 2015 Lariat Supercrew FX4 3.5 eco with 3.31s.

I run 37 psi front and 34 psi rear. I find lower psi in the rear helps some with the rear axle hop.

Daily commute average mpg runs between 19-21.5, depending on outside temperature and whether it's summer formula or winter formula gas.

My truck came with the wrangler LT265/70R17s. I run at 60 psi as they are E load tires. Ride is a bit harsh, but it probably keeps my mileage up.

I've been averaging 22-24mpg mixed.

It took me forever to arrive at 35 frt 32 rear. I wanted less in the light rear end. I wanted lower but when it gets cold the dinger starts talking. I could go lower for a better ride ~30-32 would be idea for me..
