What tire pressure do you run? STOCK CAR WITH STOCK S-02 TIRES ONLY PLEASE.

May I add to this question?
How many miles are you getting on your rear S-02s? I guess I have a heavy lead foot because I just had to replace mine with only 7,469 miles on them. This is my 5th set of rear tires including my original stock tires. I now have close to 39,000 miles on my March 2001 S2000. I got 11,612 miles on my first rear set of S-02s, then changed to other tires before coming back to them for my 4th and 5th set.

I've experimented with a variety of pressure - both street and track. In the end, I've settled on 32 all around for the street and 34 all around for the track (at least to start with). At my last track event we took temperature readings - inside, center, and outside - on all four tires after several hot laps. I only had to adjust the right front by 1/2 pound, as all the others were good.
CORRECTED
As for tire wear, my Rears were replaced at 12,000 miles and I expect to get about twice that on the Fronts.

I used to put more like 36. Can someone explain tire pressure and ride quality, mpg etc.?

Dave if you could add some thoughts to this thread it would be great.
Thanks.

Ops...... corrected my earlier post where I mis-spoke on front & rear wear. It's the rears the wear out twice as fast as the fronts.
I think that proper tire pressure is essential to good proper handling of a light weight short wheel base car.
Always check the tire pressure, if you can, when the tires are cold (ie, sitting for 1/4 to 1/2 hour) for the most accurate reading. I have my own compressor so that helps; but, if I didn't I'd stop at the closest restaurant/gas station that has air and park the car near the air hose. Go in and have a beverage or whatever. Then go out and check the tire pressures and add/delete as needed.
I don't care for the pencil type gauges that generally are very hard to read and go way too high. I prefer one that allows you to easily read the difference between pounds, actually in 1/2 pounds. It needs only to go to 50 or 60 pounds. A good one can be purchased for less than $25.
Naturally proper pressure is designed to give you even wear. Too much and you wear in the center of the tire; too little you wear on the outsides. With our tires and the stock camber settings eventually you will see inside wear first, even with proper pressure. Especially the rears. So keep an eye on the wear bars on the tires which tell you when to replace them.
When driving hard if you notice the front tires slide out first (push) in corners you can correct this understeer by raising the front pressure or lowering the rear. On the other hand, if the rears slide out first (loose) you do the opposite and lower the fronts, or raise the rears, or both for oversteer correction - which is more common with our car. This type of variation is used more when auto crossing or tracking but for most, the car is so well balanced an even all around pressure works best on the street.
That's my 2 cents on the subject.
