Plymouth Road Runner Spare Tire Sizes
The Plymouth Road Runner has used a 5x4.5" bolt pattern for all models from 1968 to 1974 along with tire diameters ranging from 26.1" to 26.7" 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 Plymouth Road Runner years and options. In this case, 145/60R20 and 165/70R17 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
