I received an ED confirmation email this week indicating that snow tires are needed..
Important information regarding pick up during winter months (October 15 until April 15)
Germany passed a ruling that requires drivers to properly equip their vehicles according to inclement weather conditions. During winter months, cars must be equipped with All Season tires (also called 'M+S tires'). It is the responsibility of the owner/driver to equip their vehicle appropriately for the prevailing conditions. The following website outlines a snow tire rental option and includes pricing and details of booking the tire rental in Germany. Please be advised that all cars must return to Munich to have the original BMW tires put back on the car before shipment to the U.S. www.edwintertires.com.
