Road trip Nitto tire pressure?

I'm taking off on a 500 mile road trip tomorrow and am wondering if anyone has any recommendations on tire pressure for the stock (TRD Pro) Nitto tires? I typically run them at 36psi and am wondering if anyone goes higher for all highway driving. Suggestions?

 

Keep at recommended pressure

 

Nope. No need to do anything special for long road trips. Any incremental mpg you might possibly gain from over inflation, you would suffer with ride quality and uneven or premature tire wire.

 

Generally, the recommended tire pressure will be best.

That being said, if your tires are not stock, or if you are hauling a significant amount of weight as (you probably will be, for a 500-mile trip) the optimal tire pressure for your specific rig may be different than the recommended pressure. In the same way that one rig handles a little different from the next, your tire pressure requirements will differ slightly as well.

One easy way to get a fairly accurate optimal tire pressure for your rig is doing the chalk test (see video below, complements of @WanderlostOverland )

I would suggest starting at the recommended tire pressure and going from there. Once you chalk your tires and drive in a straight line the chalk will either wear evenly across the entire tread surface (optimal) or you will wear the center first or the edges first. If the chalk on the center of your tire wares first, that means your tire is overinflated. If the chalk on the edges ware, leaving chalk in the center, that means your tires under-inflated. Adjust accordingly and re-test.

Keeping your tires we're evenly across the tread surface will maximize the life of your tire.

Hope this helps and hope you have a great trip!

40psi unless I’m running trails or it’s winter.
Ran my previous set at same specs and had just about 40k miles on them with plenty of tread left for another 15k-20k miles.
