Buick Electra Spare Tire Sizes

The Buick Electra has used a 5x115mm bolt pattern for all models from 1983 to 1990 along with tire diameters ranging from 26.0" to 28.3" 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 Buick Electra years and options. In this case, 145/85R18, 165/70R17 and 195/55R20 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
