Buick Regal Spare Tires
The Buick Regal used 5x115 mm, 5x120 mm and 5x4.75" (5x120.7 mm) bolt pattern variations from 1978 to 2020 along with tire diameters ranging from 25.3" to 27.3" tall. Using a temporary compact spare tire with a diameter close to the standard tire has many benefits, especially for modern vehicles with larger brake calipers and anti-lock brakes or traction control systems.
The tire diameter and the wheel diameter clearance have been taken into account for the specific Buick Regal years and options. In this case, 125/80R18, 145/80R17 and 145/60R20 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 Regal spare tire.
