The factory recommended are found inside the door jam, but its fairly safe to go up the max sidewall pressure on the tires, this is safer and more efficient, but the ride is not as smooth, if you want to play it very safe go somewhere in between these two numbers, but unless you find the ride to become annoying, a higher pressure than the recommended is fine.

Many people say that you can exceed the max sidewall, but i just dont think that it is a good idea, its up to you though!
