Oldsmobile 98 Spare Tire Sizes

The Oldsmobile 98 has used a 5x115mm bolt pattern for all models from 1977 to 1996 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 Oldsmobile 98 years and options. In this case, 145/85R18 and 165/70R17 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
