A question of tyre air pressure – 2013 Road King

My mopped was at my HD base for the 16,000 inspection last week and now I am slightly irritated, because on the inspection documents issued to me it says that the rear air pressure was set to 3.2 bar…?!? Lt. of my boardbook is the factory-side recommendation at 2.7 bar…?!? My workshop has not yet responded to a corresponding mail. And so…??!? Should I rely on a correct + conscientious work of my HD dealer, or should I address myself nac h the log, or was there from Milwaukee a revised recommendation on tyre pressure…?!? – Greetings Nico
