Oldsmobile Omega Spare Tire Sizes

The Oldsmobile Omega has used 5x100mm and 5x4.75" bolt pattern variations from 1978 to 1984 along with tire diameters ranging from 24.7" to 25.5" 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 Omega years and options. In this case, 125/80R17 and 155/70R17 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
