2016 A7 recommended tire pressures
 

Either I searched wrong or this has never come up. Why does Audi spec 3# more in the rear tires than in the front on the 2016 A7? I have always run more pressure in the front with front engined cars. My rule of thumb has been to start with +2# for front engine rear drive and +3# for front engine front drive, including my former Acura RL with SH-AWD.

I have a Porsche Cayman that specs 32# all around and this has actually turned out to be spot on, so I am inclined to think Audi may have sound reasons. I just can't figure them out.
