Buick Regal Spare Tire

The Buick Regal, an upscale mid-sized vehicle, comes equipped with a compact, temporary spare tire designed to be used only in case of an emergency, such as a flat tire. The spare tire in the Buick Regal is typically smaller compared to the car's regular tires, characterized by a reduced width and diameter. The temporary spare tire for a Buick Regal often falls into the T-Type category, also known as a 'donut,' due to its compact size. The exact size of the spare tire varies depending on the model and year of the Buick Regal but frequently used sizes include T115/70D16 and T125/70D16. However, these compact spares should not be driven at high speeds or long distances as they are not as durable or stable as the car's conventional tires. Therefore, they are only a temporary solution until the original tire can be repaired or replaced.

Buick Regal models manufactured from 1990 to 2017 have tires with overall diameter ranging from 25.4" to 27.3", allowing the use of a temporary spare tire with a near same diameter as the OEM tire. Tire diameter and wheel diameter clearance have been taken into account for the specific Buick Regal years and trims.

Listed below are compact spare tire sizes that can fit some Buick Regal vehicles based on acceptable tire diameter range of 24.6" to 28.1". Some Regal models may require the use of a traditional full-size tire as a spare. To ensure safe temporary mobility in case of a road emergency, always refer to the vehicle owner's manual for the correct Buick Regal spare tire size designated by vehicle's manufacturer.
