Datsun 240Z Spare Tire Sizes
The Datsun 240Z has used a 4x114mm (4 x 4.5") bolt pattern for all models from 1970 to 1973 along with a tire diameter of 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 Datsun 240Z spare tire selections. In this case, a 135/80R16 temporary spare tire is the recommendation for all applications.
