SUBJECT
Recommended Tire Pressure Settings
MODEL
E90 (3 Series)
SITUATION
There are two tire pressure labels located on the driver's side B-pillar.
The tire inflation pressures listed on the white tire pressure label (1) are for maximum vehicle load and are intended for speeds above 100mph. Although this label meets US regulatory requirements and the inflation pressures are valid, setting the tire pressures according to this white label (1) may result in a customer complaint of a harsh ride.
The yellow tire pressure label (2) is provided as a supplement to the white tire pressure label (1). The yellow tire pressure label (2) lists approved inflation pressures for vehicle use under 100mph. The tire pressures listed on the yellow label (2) are the recommended pressures for optimum ride comfort.
PROCEDURE
During the QC1 process and throughout the vehicle's service life, set the tire pressures to the specifications listed on the yellow tire pressure label (2) for optimum ride comfort.
