January 8, 2013I just recently purchased a set of 285/65R/18`s Nitto Trail Grapplers for my 08 FX4 and I am wondering what the recommended tire pressure should be for street/highway driving - thanks in advance!

July 16, 2014i had a set on my 03 F250 4X4(gas).
I ran 40psi in the front and 35psi in the rear.
one thing i learned working for Discount tire is that each vehicle is different. the best thing for you to do is find some flat concrete, slightly wet the tire, then drive a few feet. the water will show you how much of a contact patch you have. over inflated will give a narrow contact patch, under inflated will give you two seperate contact patches(the middle draws up and does not make good contact.
hope that helps.

July 17, 2014I hadn`t heard of D144`s method - Seems simple enough.
I`ve heard of using chalk across the tire before.
Either way, it is to see how much and where your tire is contacting the ground.
