Open your driver's door and look at the sticker.

What would you reccomend for stocker's on an STi? They call for 36F/30R.

Thanks.

Depends on the tires, but as Uncle said you're going to want to increase the pressure. For example, I just put BFGoodrich KDWS tires on and am running 40psi. I just took off Bridgestone S-03s running about 35psi. Anything higher on the S-03s were too hard for my old butt.

I'd start at 34-35psi and see how that feels.

Nonsense. It's a fine place to start then adjust up from as you see fit. I do like to keep the 6 pt. difference front to rear in my STi.

The OEM RE070s do not require any additional psi for street driving, even spirited.

Since the 05 STi is a bit camber challenged (compared to the '04) you may benefit from a few more psi, especially for autox. Just increase in 2 psi increments (equally front and rear) until you find a setting you like.

If you can't tell a difference then 36/30 is fine.

Let's STOP talking about the STi and the re070.....those are NOT regular street tires.....OK!!!!!
Get past that. The OP does NOT have an STi and what works for an STi and the re070 does NOT apply to his issue.

...and my previous post stands.

The tire pressures inside the door are for alignment purposes as well. I'm not saying that raising your tire pressure will drastically reduce the life of your tires, but if you ever had to align a car you would know what I'm talking about. I aligned a car once and forgot to set the tire pressures. After I did that it threw almost every alignment angle out of spec. My suggestion would be if you are going to run higher pressures all the time get it realigned with those pressures on the car.
