NOT A FAILURE, BUT I NOTICED A SIGNIFICANT LABELING DISCREPANCY ON MY 2009 MERCEDES BENZ SLK300. THE TIRE LABEL ON THE DRIVER'S DOOR INCORRECTLY LISTS THE OEM TIRE SIZE AS 205-55-16 FRONT AND 225-50-16 REAR. THE VEHICLE IN REALITY IS FITTED WITH 225-45-17 FRONT AND 245-40-17 REAR; THESE ARE NOT OPTIONAL TIRES/WHEELS EITHER - THEY ARE THE STANDARD SIZE AND WERE LISTED ON THE WINDOW STICKER AS SUCH. THEREFORE, IT IS ALSO NOT CLEAR TO ME IF THE SIZE DISCREPANCY ON THE LABEL ALSO MAY MEAN THAT THE LISTED TIRE PRESSURE DO OR DO NOT APPLY TO MY VEHICLE. *TR
