2017 Mercedes-Benz S550 Spare Tire

The Mercedes-Benz S550 typically comes equipped with a compact temporary spare tire, sometimes referred to as a "donut" spare tire, nestled securely in the trunk area of the vehicle. This spare tire is intended for temporary use only and is designed to get you to the nearest repair shop if one of your regular tires goes flat or becomes damaged. The exact size can vary depending on the model year of the S550, but it is typically a smaller diameter than the standard tires, often around 18-20 inches in size, with a narrower width and higher tire pressure. However, it's essential to check your vehicle's specific owner manual or consult with a Mercedes-Benz dealership to obtain the most accurate information about your S550's spare tire type and size.
