G80 5.0 was delivered with placard recommended tire pressures [F=33, R=35]. Also, believe inflation was with "N" (nitrogen), but that's a separate thought.
Over years, I've been best served having cool pressures set 2 to 3# higher than placard. I prefer easy rolling and response versus "the ride".
Would appreciate observations/comments relating to G80 "numbers".
