Porsche RS Spare Tire Sizes

The Porsche RS has used a 5x130mm bolt pattern for all models from 1993 to 1994 along with tire diameters ranging from 25.0" to 25.1" tall. Using a temporary spare tire with a diameter close to the standard tire has many benefits, especially for modern vehicle applications. Tire diameter as well as wheel diameter clearance have been taken into account for the specific Porsche RS years and options. In this case, a 125/80R17 temporary spare tire is the recommendation for all applications.
