2015 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.

2015 Mercedes-Benz C300 comes with 3 OEM tire size options. Select the original equipment the tire size installed on your vehicle to see all spare tires that have roughly the same tire diameter and can be used as a temporary replacement in the event of a flat tire. Remember that load carrying capacity of the spare tire must be the same or higher than the load carrying capacity of the original equipment tires in order to safely support the weight of your vehicle. Refer to vehicle owner's manual or contact Mercedes-Benz dealership to confirm the correct 2015 Mercedes-Benz C300 spare tire size.
