When I initially got my Raptor a few weeks ago it had an aftermarket wheel that I had the dealer replace with the upgraded Ford Forged beadlocks. The aftermarket setup had the stock tires on it and they were set around 38 PSI. I believe when they swapped out the wheels they just kept the tires on from whatever vehicle they took them off of (which is fine as they were brand new and still had the manufacturing marking lines on them). However the PSI is not 46-48. What is the correct pressure to be running a daily driver at on stock tires with the forged bead locks?

38 PSI is the door placard / owners manual recommended pressure for stock tires, stock wheels on a Rap. The ride may be a little harsh at that pressure, and there are a lot of folks running slightly lower pressure. I’ll run 38/37 on trips where economy is more of a concern, but tooling around I’m good with about 36-37 front, 34-35 rear.
the 46-48 psi most of us see at delivery is that way to stabilize the trucks on rail cars. A firm tire will not bounce as much in transit reducing the potential for damage. especially on a truck with so much suspention travel as the raptor.
Inept dealer deliver process is to blame for the 46-48 deliveries, The tires should be aired down to door jam specs of 38 at delivery.
I run 38 front and 34 rear.

I'm 38 Front and 37 rear.
California Freeways are my reason. Going to play with the pressures later this weekend. Going to try 36/36

Hard to say. So many variables on a tank of gas.
I GENERALLY get 17-19 mostly highways regardless of 1-2 lb variance. Ride changes though.
That is why i keep the fronts at 38. Lowering the rears keeps the back end planted and less jumpy on highway expansion joints ...especially when in a curve.
19 mpg is possible on the highway at 64mph. Hit 67mph, and it drops to 15mpg. As soon as you start boosting, you are toast. My problem is, i tend to run 85-90mph.

I didn’t believe it until I tried it. 38 psi front and 34 psi rear. Haven’t noticed a change in mileage but ride quality is much better.
