Proper tire pressure is the same if the tires are 15, 24 inches or anywhere in between.

Whaaa? You don't inflate your tires to what the max psi on the tire says, you inflate it to what the manufacturer says per the model of the car. This is always on the sticker on the inner surface of the driver's door. You can adjust it from there to preference.

33 psi is 33 psi no matter what shape or size of a container it's in.

I'm not sure I agree with your answer. The load ratings on low profile tires are different than stock and require more air. I have 245/30 and 295/25 and try to stay in the 38-40 psi range. Running 33 psi may give you a better ride, but once you hit a minor pot hole, considered yourself screwed.

33 psi on a 30 profile???????? Yeah if you want dented wheels. The pressure should be at at least 40 psi to protect the wheel. The shop I used to go to would set them to 42-44psi. I brought then down to 40 and have had no issues.

i would say 37 or 38. you dont want too much or else when you hit a pothole, there will be no where for the air to go.

this is interesting. I just got 20's and ive been putting in 35.. now i might put in a few psi more...

Out of complete curiosity and off topic. when i had a shop put my 20's on the TPMS never popped up with an exclamation point. I thought it would pop up with some kind of alert but nothing. No lights on my dash....

there is no absolute right or wrong pressure, it's probably more of a personal preference than anything. it's absolutely fine to put 33psi in 20s, my friend did that and never had problems. but like some said, it's putting a bit more risk on bending your wheels, but that's another topic.

to me i never put more than 40, even at 40 i think is a bit on the high side unless you are fan of riding harsh.

Interesting. I've always put 33 psi in my 19" (35 series) tires. Maybe I should consider putting a bit more in as per the suggestions here...
