Factory tire sizing and recommended inflation pressure guidelines on the 2023 Mercedes S-Class are managed by B-pillar compliance certification labels, owner manual charts, and vehicle load ratings.
How to Fix It:
-
Check Driver Door Pillar: Open the driver’s door and look at the placard affixed to the B-pillar to find exact front and rear tire size specifications and cold pressure requirements.
-
Review Sidewall Markings: Inspect the molded sidewall lettering on your current tires to match the approved width, aspect ratio, and load index.
-
Adjust for Load: Modify your target inflation pressures according to whether the vehicle is operating under normal loads or maximum passenger and cargo capacity.
