By law, the correct tire pressure should be on inside of your door where the door meets the body and also somewhere in your owners manual. Do a search next time because whatever you need to know is USUALLY already posted somewhere else...and it should be around 45PSI.
As long as you respect the minimum and maximum recommended pressures I don't don't think you'll have a problem. Mazda recommends 34 psi front and rear for my 15s. Toyo recommends 44 psi. I run 'em at 44. The car is a bit more pointy that way and I figure the extra 10 psi may help fuel economy.

Just to note: The tire inflation on the tire itself is the manufacturer's MAXIMUM tire pressure. It has nothing to do with what they recommend. When push comes to shove, they will tell you to follow the vehicle manufacturer's recommended pressure.
what some of you fail to realize is that when you get different size tires, you can't always go with what's on the door. in that case, go by the tire manufacturer's recommended settings. i run 36-38psi in my 225/40/18's.
