Mercury Zephyr Spare Tire Sizes

The Mercury Zephyr has used a 4x108mm (4 x 4.25") bolt pattern for all models from 1978 to 1983 along with tire diameters ranging from 24.2" to 24.9" 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 Mercury Zephyr years and options. In this case, a 135/80R16 temporary spare tire is the recommendation for all applications.
