What tire pressure?

[ArkansasMystic]

I am running Nitto 555's on my cobra (daily driver). What is the best tire pressure for good performance and traction? I know there is a range on the side of the tire, just curious to see what you guys are using. I will be dragging it a little, but my main concern is just for road performance. Thanks.

I run 40 PSI up front and 32 psi out back.

I like 35 lbs all the way around.

you could probably run 25-30psi on the street and then 20 at the track. Or run 20 all the time but they wont wear evenly. BTW are they just 555's or 555 drag radials?

They are the regular 555's. I am not gonna race much, but I thought about lowering the pressure to get better traction. However, I have heard that lowering too much could reduce speed. I am trying to find a happy medium so that it will be fine for the street (it is my daily driver) and also be good while at the track (would like to leave a constant pressure and not go up and down all the time). I will throw a gauge on them hopefully tomorrow and see what they are at, and probably lower them to 28-30. I don't race enough to justify buying the drag radials (atleast not until I NEED new tires), so trying to find a different way to help traction. Thanks, and any more input is appreciated.

32 in the front and 30 in the rear for street use

You should always run what it says on the door sticker. I think its 32psi no matter what street tire it is. You should never lower the air pressure on a street tire for the track you can ruin the tire and you will have less traction.
