Mercedes-Benz C300 Spare Tire

The Mercedes-Benz C300, like many luxury vehicles, does not come standard with a physical spare tire, instead it implements run-flat tires or has a tire repair kit for temporary fixes. This approach helps with weight reduction and allows for more storage space. However, for those occasions where a spare tire is necessary, it is important to know the specific size for the Mercedes-Benz C300. It generally takes a size of 225/50R17 for front and rear wheels. Moreover, two types of spare tires can be considered - a full-size spare tire (matches the size of the car's regular tires and can be used as a normal tire once installed) or a compact temporary spare tire (smaller than regular tires, also known as a 'donut', intended for short-distance emergency use). Always remember to consult your car's user manual or a tire professional to ensure the correct spare tyre is purchased and installed safely.

Mercedes-Benz C300 models manufactured from 2008 to 2025 have tires with overall diameter ranging from 25" to 26.1", 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 C300 years and trims.

Listed below are compact spare tire sizes that can fit some Mercedes-Benz C300 vehicles based on acceptable tire diameter range of 24.3" to 26.9". Some C300 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 C300 spare tire size designated by vehicle's manufacturer.
