Tire Pressure

What tire pressure do most of you use for your Q5? The manual and the door jam sticker recommend 33 psi. But when I picked up my Q all four tires had 42 psi. I reduced that down to about 36 psi (cold). I assume the dealer checked them and must have considered 42 to be correct. It does seem to ride less harsh now with 36 instead of 42 but I don't want the tires to wear unnecessarily.

Audi engineers in cooperation with tire manufacturers with testing have found optimal pressures in the tires and you have the sticker on the door with the necessary pressures
Tolerance is 3%
Factories puts more pressure in the tires because of transportation and because it is not known how long the vehicle will stand in stock

It is not correct
When the car is under load, then a recommendation 2.7bar = 39 PSI 3.0TFSI, For 2.0TFSI is less 2.4bar =35PSI
This is Audi recommendations
