2008 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.
2008 Porsche Cayenne comes with 7 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 Porsche dealership to confirm the correct 2008 Porsche Cayenne spare tire size.
