Tires: tire pressure, recommended tire pressure, german cars

Question
i have a 2006 audi a4 2.0t, i just recently bought pirelli pzeronero tires for it , what is the recommended tire pressure? the tire size is 235/45/zr17

Answer
Thomas,

If my book is correct, this is the original tire size so the vehicle's placard will have the information.  The placard is usually located on a doorpost or in the glove box, but I've also seen it in the trunk and on the fuel filler door.

My book says 32 psi all around, but many German cars list several pressures dependent on the driving condition, so it's best to check against the placard.
