Porsche 718 Boxster Spare Tire
The Porsche 718 Boxster, like many modern high-performance vehicles, does not come with a conventional spare tire. Instead, it is equipped with a tire repair kit that includes an air compressor and tire sealant, designed to provide a temporary repair and get the driver to the nearest tire repair center. This is mainly due to weight reduction, saving space and designing the vehicle with optimal performance in mind. For those who insist on having a spare, it needs to be noted that there's no specific storage space for it in the vehicle and the size will be dependent on the standard tire size of the Porsche 718 Boxster, which is 235/45R18 for the front and 265/45R18 for the rear. In addition, it's always recommended to contact the vehicle's manufacturer or professional automotive technician for accurate information.
Porsche 718 Boxster models manufactured from 2017 to 2025 have tires with overall diameter ranging from 26.3" to 26.5", 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 Boxster years and trims.
Listed below are compact spare tire sizes that can fit some Porsche 718 Boxster vehicles based on acceptable tire diameter range of 25.5" to 27.3". Some 718 Boxster 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 Boxster spare tire size designated by vehicle's manufacturer.
