The correct tire pressure depends on the tire. The max pressure will be listed on the sidewall of the tire. I usually run about 5lbs less than the max. Always check your tire pressure when the tires are cold.

Check the label on the driver's door jamb or in the owners manual for the proper pressure. The pressure listed on the side wall of the tire is the max safe pressure of the tire only.
