What tire pressures are you guys with stock 15" SE-R wheels running?

Right now I am have 205/50 Pirelli P700z's with 37-38psi in the front and 34-35psi in the rear. I got those numbers from Kojima on SE-R.net. Anyone else?

I usually run 33psi front, 30psi rear cold. The tires are Bridgestone RE71, 205/50R-15 on 15x6.5" Power Racing VS-04 wheels. On the NX (Bridgestone RE71, 195/55R-14, stock wheels) I run 35psi front, 30psi rear cold.

Shouldnt you run the pressures that are on the sticker on your drivers side door jam? I run 32 front 29 rear like it says to.

Ok, now is this true....that both slightly over-inflated and under-inflated tires will make the car handle worse?

I know drove home once from the dragstrip after I dropped my front tires to 22psi, the car handled very sloppy and seemed to lean more. I'm wondering thought if what I have now (38 front, 35 rear) is too high which might also cause handling problems.

I use 33/30 (F/R) on my 195/50 ZR 15's. The sticker on my driver's side door frame says to use 33/29 for the stock 185/60 14's.

Do you happen to have a link to Kojima's information on SE-R.net? I'd really like to read it. Thanks a lot.

Tire pressures *should* depend on how your car is handling, in general. On the street, though, you should be fine with the pressures you listed.

The pressure difference between front and back can vary by as much as 8 psi when I autocross. 1 of 2 psi out of the rears can do wonders for a car that pushes (oversteers).

For the street, though, I'd keep all 4 within 2-3 psi of one another. Should be fine.

SE-R.net under I think Engine Tuning Tips or something. It's a huge database of stuff, all from Kojima.
