SUBJECT
Noise and/or Vibration Caused by Irregular Tire Wear
MODEL
E60 (5 Series) equipped with Dunlop SP Sport 01 DSST Run Flat Tires
[NEW] INFORMATION
The affected tires can be identified by the sixth and seventh digits of the DOT number, which is embossed in the tire's sidewall.
Refer to the chart listed above to determine whether a tire is affected by this bulletin. Note the specific tire size and compare the tire's DOT number to those which are listed in the chart. Please note that the
last four digits of the tire's DOT number will be numeric. The chart listed below shows XXXX for the last four digits of the DOT, since these numbers will vary from tire to tire.
Only tires which have been produced with the DOT numbers listed above are eligible for replacement under the guidelines outlined in this bulletin.
Tires which carry the Run On Flat designation, embossed on the tire's sidewall, are not affected by this bulletin.
SITUATION
Noise and/or vibration caused by irregular tire wear on Dunlop SP Sport 01 DSST Run Flat tires may be objectionable to some customers. Irregular tire wear may also be noted during a service visit.
CORRECTION
If this situation is detected based upon a customer complaint and/or during a service visit; and only if the tires have less than 20,000 miles, replace all four (4) tires.
PROCEDURE
Check all four tires for proper inflation pressure and tread wear each time a customer comes into your center.
Noise and vibration may be caused by the irregular tire wear referenced in this Service Information. The wear only occurs at the tire's inner shoulder as indicated by the shaded area in the illustration.
The tires will have a feathered or scalloped edge on the inner tread blocks. If one or more tires are found with this condition, and the tires have less than 20,000 miles, all four (4) tires should be replaced with similar Dunlop tires, or when not available, with other BMW approved tires.
Assistance for situations outside of the scope of this Service Information will require submission of a PuMA case with required tire information such as DOT number, tire pressures, tire mileage, and digital pictures (if possible).
