2025 Porsche Cayenne Spare Tire
The Porsche Cayenne, a luxury SUV from the renowned German automaker, is equipped with a space-saving spare tire, often referred to as a "donut." This sort of spare tire is typical of many modern vehicles due to its compact size, allowing it to be stored more conveniently in the vehicle, usually under the trunk. However, due to its size and design, it is meant for temporary use only to get you to your nearest service center and should not be driven at high speeds or long distances. The size of the spare tire for a Porsche Cayenne can vary, but a common size is 195/75-18. It's recommended that owners check their specific vehicle manual or their spare tire itself for the correct size. Also, keep in mind that when you need to use it, the car's ground clearance may change.
