Alfa Romeo Spider Spare Tire Sizes

The Alfa Romeo Spider has used a 4x108mm (4 x 4.25") bolt pattern for all models from 1967 to 1993 along with tire diameters ranging from 24.2" to 24.7" 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 Alfa Romeo Spider years and options. In this case, 125/70R17, 135/70R17 and 135/80R16 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
