After much research on this board, I went with one person's favorite of 35f/32r. The ride is a little more stiff, but it feels much better.

The listed pressure's in your door jamb are WAY TOO LOW. When I had the stock 92's I would run 40lbs. all around give or take 2 lbs. If you do any aggressive cornering with 32lbs. in the front you will notice that the tire is folding over and your running on your sidewall. Thats not good.

35 Ibs all the way around! And YES the factory door jam Ibs are WAY to low! Door jam level is for the Joe Shmo driver that doesn't do much hard cornering

Depends on the tires and the use....
when I'm wearing out the RE-92's that came on some 99 RS wheels, 35 all around. With the 215-45-16 Azenis: track: 38F 34R street: 40 all around this balances the wear jack |

Changing your driving style is probably better than just blindly adding air pressure. I switched to the higher pressures not because of rollover but because I simply liked a snappier feel. Even with the stock 32f/29r I never roll over during spirited driving. Smooth lines equals zero rollover under most circumstances.
My first autocross season, even when I was running 45f/45r, I still rolled over because I didn't know proper braking and cornering. Now that I've learned proper braking and lines, I can easily autocross on stock pressures and just barely roll over. I'll be slower but being smooth is more important than being fast when you're first starting out.

Mine came 41f/40r from the dealer and I haven't made any adjustments yet and have never rolled over the sidewall arrows.

To find out if you really need more air, mark your tires with chalk or shoe polish. If you rub off the marks past the "safe" line, you need more air. Look at the marks on this tire and you'll see the pressures are absolutely dead on for the conditions of the track because the marks line up exactly with the rollover line (NHIS road course, November, 60 degrees, 38f/35r, Bridgestone RE730 215/45ZR17):
The fronts, however, had some rollover and should have been upped to around 40f: And warm tires are gooey tires: Of course, the pressures can be fine tuned further for desired performance handling but the rear marks show how to set pressures initially and then fine tune later.

Should be the same pressures. There is no "correct," only what is correct for you driving. Experiment with it until you find something you like.
Despite what I said 3 years ago (eek), I have since moved on to 35f/34r |

thanks gjhsu
ya i understand there is no correct pressure but i m just wondering what tire pressure will be optimal for my tires in the sense of tire wear cuz i understand the fact that too much or too little pressure will cause the tires to wear out a lot of quicker |

I ran something like 44/42 in the RE92s...took out some of the wallow, but they just have very soft sidewalls...still, that was much better than the suggested placard pressures.

Sorry to bring up an old thread,but I had been running 35-38psi on my stock tires and just changed to 28 front/32 rear at a fellow owner's advice,and the steering actually feels great! Probably the added weight of the lower pressure helps,plus he said this is a good setup for weight transfer in straight-line acceleration.I first thought this was a weird setup,but it feels good.
