With any tire you choose I always say play with the tire pressure until you find a set up you are most happy with.
For me in this tropical climate 38 psi give me an overly bouncy ride.
I make sure the tires are cold when I check the pressure.
I use a digital gauge that read half psi increments.
What I have noticed is that the truck reads psi in full increments.
For example if I put 36.5 psi in the tires the display will read 37. So don't necessarily use the display readout when you are fine tuning your optimal psi settings
