Mercedes-Benz S400 Spare Tire

The Mercedes-Benz S400 is typically equipped with a compact spare tire for emergency use in the unfortunate event of a flat tire. This spare tire, also known as a "donut," is used as a temporary solution to get the vehicle to the nearest service station, not for long-distance travel or high-speed driving. The compact spare tire is usually smaller and lighter than the regular tires, which allows it to be more easily maneuvered and installed when necessary. The exact size of the spare tire can differ based on the specific model year of the S400, but it is generally smaller in width and diameter. It is always recommended to check the owner's manual or consult with a Mercedes-Benz dealership to confirm the exact type and size of the spare tire designed for your specific Mercedes-Benz S400 model.

Mercedes-Benz S400 models manufactured from 2010 to 2013 have tires with overall diameter of 27", allowing the use of a temporary spare tire with a near same diameter as the OEM tire. Tire diameter and wheel diameter clearance have been taken into account for the specific Mercedes-Benz S400 years and trims.

Listed below are compact spare tire sizes that can fit some Mercedes-Benz S400 vehicles based on acceptable tire diameter range of 26.2" to 27.8". Some S400 models may require the use of a traditional full-size tire as a spare. To ensure safe temporary mobility in case of a road emergency, always refer to the vehicle owner's manual for the correct Mercedes-Benz S400 spare tire size designated by vehicle's manufacturer.
