on the gas cap i think it says like 26.... but thats way to low the tires show wear on the outter edge from under inflation.. i have them set to 32... and the seem alright .. but what doest everyone have theirs set at.. i have the stock wheels with 205/65 sooo stock tires as well...

that's funny on my gas cap it says front 32 and rear 34...unless you carry a heavy load...maybe it's different the 420 compared to 560...
I'm in europe, my cap says 2.2bar on the front and 2.3 on the rear - the tires look deflated, but hey - it's a heavy car and they knew what they were doing 
it's supposed to be soft, not hard...
Side wear is normal, it's because of declination of the wheel when turning.

The sticker on my cap has three settings, two for summer and one for winter.
Summer normal front 29 PSI, Summer normal rear 30 PSI
Summer maximum front 30 PSI, Summer maximum rear 35 PSI
Winter front 33 PSI, Winter rear 38 PSI
Warm tires: +7 PSI
For driving more than 100MPH: +9 PSI
I run mine year round at 30 PSI in the front and 33 PSI in the rear, and I don't have any in irregular tire wear issuses.

well so far like i said the 32 seems alright.. ill see how it goes after i put some mileage on them
Remember guys. The tire pressure amount stated on the gas door is for OEM tires. (whatever brand/size/models came on the car from Mercedes.) I'm sure that all of us have some other brand on our cars by now. It all boils down to the type of rubber used by a manufacturer and side wall strength, blah, blah. Two tires from two companies with the exact size dimensions will probably have different pressure ratings.
A good rule of thumb is to put about 6-8 psi less than the stated maximum allowed for your tires. This allows for tempurature variance and road conditions. Too little air in the tires puts major strain on the sidewalls.
BTW, I'm running 38psi on tires with a maximum of 44psi. Very smooth. And I rotate 'em every 5K.
