I just changed the tire size on my SuperCrew from the 255/70-16 to the 275/60-17. Can someone whose truck originally came with this size tire tell me the Ford recommended inflation pressures for them? Any thoughts for pressures other than factory spec? The tires are Duplop Sport Rover on factory 17 inch aluminum sawtooth wheels with custom paint.

I have a SuperCab so it might be different than a SCrew. Ford calls for 26 front, 32 rear with 275/60R17 on mine. I run 32 all around.

 

i run about the same, 32-33 up front, 35 in the back
