MOExtended tires (tires with run-flat properties)

MOExtended tires (tires with run-flat properties) allow you to continue driving your vehicle even if one or more tires are entirely deflated.

MOExtended tires may be used only in conjunction with the activated tire pressure loss warning system or the activated tire pressure monitoring system and only on wheels specifically tested by Mercedes-Benz.

You will find notes on driving with MOExtended tires in the "Breakdown assistance" section.
