tire pressure

[Richie7]

What is the optimal tire pressure for stock '08 tires everyone is using for street driving? How about at a drag strip?
Thanks for the info,

2 bar = 29 psi. Sticker drivers door (street).

For the Drag Strip, work your way down to 19 psi and no less because with hard launches the wheel will start to spin inside the tire at about 18 psi
