Porsche Boxster Spare Tire Sizes

The Porsche Boxster has used a 5x130mm bolt pattern for all models from 1997 to 2016 along with tire diameters ranging from 24.9" to 27.4" 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 Boxster years and options. In this case, 125/80R17, 155/70R17, 125/70R19 and 145/60R20 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
