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.

Porsche 718 Cayman models manufactured from 2017 to 2025 have tires with overall diameter ranging from 26.3" to 26.8", allowing the use of a temporary spare tire with a near same diameter as the OEM tire. Tire diameter and wheel diameter clearance have been taken into account for the specific Porsche 718 Cayman years and trims.

Listed below are compact spare tire sizes that can fit some Porsche 718 Cayman vehicles based on acceptable tire diameter range of 25.5" to 27.6". Some 718 Cayman models may require the use of a traditional full-size tire as a spare. To ensure safe temporary mobility in case of a road emergency, always refer to the vehicle owner's manual for the correct Porsche 718 Cayman spare tire size designated by vehicle's manufacturer.
