Forgot to mention that I have an ARB bumper. Not sure if that changes anything and am running the TF 2" medium duty suspension.

 

When I get a new the type of tire on any of my vehicles I put the vehicle in the street and smear sidewalk chalk in a line on both left tires, drive a couple of blocks, and add or subtract air until the line wears evenly. Make note for front and back and be set. It is best if you have a few colors of chalk.

Having said that, I usually subtract a little for ride comfort. On my Toyo's (in m signature? Can't remember... about the same as yours) I have 38 I front and 34 in back.
