Tire Pressure?
#12
The best tire pressure for handling will be different from car to car, tire to tire and many other conditions (like load). I have seen video clips of one of the best ways to find your pressure. (You'll have to a search on it... I am at work right now) Basicly you mark your tread and sidewall with white shoe polish, chalk or something like that. You do some hard cornering... like figure 8's in a parking lot. You adjust your tire pressure to where you wear off your markings on the tread but NOT the sidewall. (This will take a bit of trial and error.) The pressure you come up with will be the best for traction as you are using the whole tread. The best pressure for gas milage will most likely be a little higher.
Unless you are very **** about checking your tire pressure, I would put in a few pounds more than the "best" pressure to allow for a little leakage.
See this link -- It is not the video but it is the procedure:

Audi suggests you use original sized tires (maybe because they were tested at high speeds and cornering at Nürburgring) and always put the front and rear pressure (driver door frame) those sized tires should be at when the tire is Cold..once you change tire or wheel size then need to use the markings on the tire according to load.

Well, I'll answer up, even though it an old thread
I keep my tires at 38psi. The sticker on mine (in the gas door) says 36psi with 1-2 people, and 42psi for 3-4 people and some load. The tires (Michelin Exaltos) are Load Range 'C' and 44psi max rated.
These cars are heavy and I absolutely believe that the recommended pressures are higher than the 'econobox' normal 32psi.

Always check tire pressure when the tire is cold. The rear right doorjamb should show a pressure table. Mine states 35 lbs for 17" oem wheels with normal loads; 41/46 when fully loaded. I generally run 36 lbs because I do mostly highway driving. Result: second set of Pirelli P6 Fourseasons were just replaced after 50k miles (rated for 40k). Correct pressure and rotation every 5-6k pays off in long tread life.
