Porsche 918 Spare Tire Sizes

The Porsche 918 has used a 5x130mm bolt pattern for all models from 2014 to 2015 along with tire diameters ranging from 27.3" to 28.7" tall. Using a temporary spare tire with a diameter close to the standard tire has many benefits, especially for modern vehicles with larger brake calipers and anti-lock brakes or traction control systems. Tire diameter as well as wheel diameter clearance have been taken into account for the specific Porsche 918 years and options. In this case, a 155/65R20 temporary spare tire is the recommendation for all applications.
