2019 Porsche 718 Cayman Spare Tire
The Porsche 718 Cayman does not traditionally come equipped with a spare tire due to its sport-focused design which emphasizes lightweight performance. Instead, the vehicle incorporates a Tire Repair Kit, which includes a bottle of sealant and a compressor, allowing for temporary repair for safe travel until professional repair can be sought. If a driver prefers to have a physical spare tire, it's important to consult with a Porsche dealer to recommend the correct size and type. However, it's noteworthy that the adding of a spare tire adds weight and can affect the performance and storage space of the car, as the Porsche 718 Cayman doesn't have a designated spare tire well.
2019 Porsche 718 Cayman comes with 3 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 2019 Porsche 718 Cayman spare tire size.
