2017 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.

2017 Buick Regal comes with 3 OEM tire size options. Select the original equipment the tire size installed on your vehicle to see all spare tires that have roughly the same tire diameter and can be used as a temporary replacement in the event of a flat tire. Remember that load carrying capacity of the spare tire must be the same or higher than the load carrying capacity of the original equipment tires in order to safely support the weight of your vehicle. Refer to vehicle owner's manual or contact Buick dealership to confirm the correct 2017 Buick Regal spare tire size.
