heith is right, there are a million things to consider when setting your tire pressures. A few tips, when you set your pressures be sure to do it in the morning when the tires are cold and don't reset them! 30-30 on street tires should be fine. If you're on race tires the pressure are usually within a few pounds of each other.... unless.... you're on the pilot power race. The rear pilot power race needs to be run with as little as 20-24 pounds or you'll cold tear the shit out of it!! Only the rear needs to be that low, the front pilot power race is just like any other slick.
