Buick Riviera Spare Tires

The Buick Riviera used 5x115 mm and 5x4.75" (5x120.7 mm) bolt pattern variations from 1979 to 1999 along with tire diameters ranging from 25.2" to 27.4" tall. Using a temporary compact spare tire with a diameter close to the standard tire has many benefits, especially for modern vehicle applications.

The tire diameter and the wheel diameter clearance have been taken into account for the specific Buick Riviera years and options. In this case, 125/80R18, 145/60R20 and 145/80R17 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters. We've provided a breakdown by vehicle generation and model specifics to help you find the correct Buick Riviera spare tire.
