Does anyone have an explanation to why the recommended tire pressures in a dually the fronts are 75psi and the rears 60psi? With a payload figure of 4995 I would think you'd want more pressure in those rears too. I know it's spread over 4 tires but still curious.

Any thoughts, opinions, all knowing answers?

 

The 2015 F350 placard for my dually shows 65psi in all positions regardless of payload.

 

Mine is an 08 and has 75 up front.

 

My dually states 75psi front & 60psi rear also. I run 75psi all around.

I would say they recommend 75psi front & 60psi rear for best ride & drive quality, the 75 in the front for the weight of the engine (running 60 may result in wishy-washy steering), the 60 in the rear for a smoother ride (running 75 in the rear will result in a rougher ride), this is because the weight is spread over four tires instead of two.

I saw a section of the forum that was titled "ask ford engineering" or something like that....and of course..you couldn't post any questions...but this would be a good question to post in such an active section.
