quick question? if i change my tires to 13s what should be the tire pressure since my 15s requires 32psi-34psi as seen on the sticker on the car.

Tire pressure is very subjective and its a trade off no matter what pressure you use. However, you can probably run the same pressure and be fine.
I run all my tires at higher than recommended by the manufacturer though. It gives better fuel efficiency, gives better steering response, better wet traction, and reduces tire wear. Lower pressure can give better snow traction, and a more comfortable ride.
I encourage you to play around with the pressure no matter what tire size you use. Even changing from one tire to the next can lead to huge changes in handling. Tweaking tire pressure allows you some control over how you want your car to handle and ride.
