Proper tire pressure

I just bought a 2013 Toyota Tacoma V6 TSS Sport Series. This is the cleanest used vehicle I have ever seen. One owner with 79,000 miles. All tires are new Good Year Wrangler 265/65R17 112 T. the pressure shown on tires is 51PSI. This is not what the manual calls for and it rides sort of rough. The truck has the tire pressure warning system.
What pressure should I use? any assistance will be appreciated.

 

Look inside your driver's door jamb it tells you the correct tire pressure for the 265/65/17 tires

 

Thanks, Unchained. Found it in the door jam.. Have a fantastic day.

 

Anytime that's what we are all here for

 

The pressure on the tires is the MAX (for heaviest load ability) and since tires are used on different vehicles, you need to adjust for your vehicle and your load. The door jam numbers are a place to start IF the tires are the ones the truck was sold new with.
The true way to judge the pressure is to perform the CHALK TEST!

Sidewall max pressure is never the operating pressure.

Do what @Unchained 5150 says.

Then do a chalk test on the tread and tweak as required, assuming your alignment is correct.

 

Correct just did that chalk test myself with my new different size tires. But I would bet since he put the same size tires on the stuck tire pressure will be just fine

 

Different tires have different air needs... even if the same size.
