2025 Porsche 911 Spare Tire
Porsche 911, due to space and weight-saving considerations, doesn't come with a traditional full-size spare tire. Instead, it includes a compressor and tire sealant to aid in the repair of a flat tire temporarily to ensure you get to a service station. However, the recommended size for a spare tire, if you decide to have one, would be fitted according to the car model, wheel size, and specification, typically falling in a range of 17 to 20 inches. Given the high-performance nature of the Porsche 911, it is crucial to choose high-quality, performance-approved tires to maintain the vehicle's handling, speed, and overall efficiency.
2025 Porsche 911 comes with 4 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 2025 Porsche 911 spare tire size.
