2007 Mercedes-Benz R63 AMG Spare Tire
The Mercedes-Benz R63 AMG, a high-performance luxury crossover SUV, has a typical spare tire located under its cargo area. The automaker recommends using only the manufacturer-specified spare tire for the R63 AMG, which belongs to the run-flat tire category. These tires are engineered to resist the effects of deflation when punctured, enabling the driver to continue to drive at a reduced speed (up to 50 miles at speeds up to 50 mph) with decreased performance until they reach a safe spot for tire changing or repair. The size of the spare tire should be compatible with the size of the car's standard tires, which are 265/45R20 (104Y) front and rear. When replacing, the use of original equipment (OE) tires is encouraged. Non-standard tires may affect the functionality of the vehicle's 4MATIC four-wheel drive system and it's advanced active safety technology systems. Mercedes-Benz does not recommend installing a winter version of the same size tire on the R63 AMG and using it as a permanent spare tire. It is considered a temporary solution due to its limited capability, and driving long-term or at high speeds on the spare tire is discouraged. It is always necessary to consult with a tire specialist or Mercedes-Benz dealership to ensure the correct spare tire is used for the R63 AMG.
