What tire pressure is best?

The max recommended psi on my Goelander stock tires are 44psi. The door sticker states 32psi all around, I keep them at 36psi.
 
I'm running the 265/75 R16 BFG T/A KO and have been playing around with the tire pressure this winter out here in Cali. I found that 50 PSI yields the best mileage and control on the freeway. Max pressure is 80 PSI. For summer, I'll run them at around 40.

Tire Pressure is "Pounds Per Square Inch". It should not matter the size of the tire. The pressure inside of them would be equal. If the manufacturer's recommendation is 32 then that is what you should use when driving under normal conditions on surfaced roads. For you guys increasing it 6 to 10 pounds, first you may be exceeding the max pressure indicated on the sidewall, and in the summer time when the heat and friction kick this up another 5 or 6 PSI, you are really exceeding the capabilities of the tire. Since when have you all decided that the manufacturer of the tire is incorrect and that what you think is better. Safety, tire wear, mpg, are all considered in this. You go outside these parameters and you are creating a possible problem.

I do agree that the recommended psi on the door jamb is important to consider.
But Im always amazed at Toyota's recommendation. 32psi seems very low.
I have a new Trail Edition and when I checked my tires they were at 40-42psi, and thats from the dealer when delivered new.

Doesnt 32 decrease the mpg? Increase tire wear?
It makes a bigger contact patch but at what cost?

The auto manufacturers make those recommendations based on best average mpg, ride quality, and comfort. Unless I specify differently my tire rotations almost always end up with the tire tech setting them at the max pressure on my sidewalls and the resulting ride feels like I'm running on basketballs. So when I get home I air them back down to what I consider a decent ride while not going below the door recommendation. I also usually carry a couple hundred pounds of gear in the back, so I am aired up a little higher than the door recommendation. I try to run between 35 -38psi, but that's just my preference.

I ran into the same issue with my 89 Land Cruiser. The door jamb recommendation was way low.
Some say it was a comfort issue.
I guess 35-38 is a reasonable compromise for my 4Rnr.
But I suppose I shouldnt look into the fact that the vehicle left the dealer with 40-42psi. Maaaaaybe not much thought went into that.
 
the TP in the 40's is due to transport shipping. during the PDI its suppose to be dropped down but its missed a lot.

I run 32psi but that's just for comfort since the 20's have such a short sidewall.

I would love to get 17's with a taller sidewall for impact softening, but I am on the fence of keeping or swapping for a 6th gen when they come out.

Yeah, the dealer was so anxious to get me out the door with this vehicle I doubt they did any prep at all. There is no pre-delivery service entered into the Service History log.
 
Just put my summer tires back on. Running a 275/65/18 tire with 35 psi. Seems just right.

32 PSI for all (including spare).

That's what I thought and am running but having a strange issue with em. If I leave em sit for a day or two without driving they will "flat spot" like a bias ply swamper. This causes the steering wheel to shake back and forth for a couple miles. It happened a couple times.
 
I have nitto ridge grapplers C load 285/70/17. 50psi on sidewall marking. Had them at install at 40front 40 rear. Did 10K service and dealer set at 50front 35rear. Rides fine not much front dip as stock Duellers. also not as much rear bounce as before.

So please correct me if I am wrong. Looking at that chart, the 4runner comes with p265/70/17 tires at reccomended 32 psi. If you change to a LT tire of the same size you should be running at 50 psi?

What load rating are you asking about?

Also, do be more precise you should weigh your vehicle

What's the factory load rating, I can't find it online

(Also keep in mind that if you do direct conversion it will be for more weight than you are likely running, go hit a weight scale)
