Tire pressure for 285/75/R16

I just put on some Nitto Ridge Grapplers on my 09 Tacoma trd offroad short bed with arb campershell.

After going through some light mud I noticed the tire contact patch in the rear is only in the center and not the whole width of the rear tires. They are currently at 38 psi
What tire pressure should I be running with these?

 

31 PSI

 

ok ill give that a try, Im running 33 psi right now and it seems to be better. What psi do you run in the front? Im at 35 in the front right now?

 

I have been running between 33 and 35 psi on my 285/65/18 Trail Grapplers for the past 3 years with nice even tread wear. When you start getting below 33 psi a change in the weather can make your TPM sensor go off.

 

Your tire has slightly less volume, requiring greater pressure than a LT285/70/17.

In fact, 31 psi in a LT285/70/17 is equal to 33 psi in a LT285/65/18, as far inflated load capacity of the tires.

 

Wow I learn things on here every day. Guess there is a Science to everything. Thanks Guy's

 

I run 37 psi all around, but my tires are LT265/75/16...

Between 30 and 35 PSI , your tires have a load capacity value of 42 lbs a tire per 1 PSI.

Guys who run a front to rear bias usually 'underinflate' the rear tires.
