Geo Storm Spare Tire Sizes
The Geo Storm has used a 4x100mm bolt pattern for all models from 1990 to 1993 along with tire diameters ranging from 22.7" to 23.1" 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 Geo Storm years and options. In this case, a 125/70R16 temporary spare tire is the recommendation for all applications.
