Buick Regal Sportback Spare Tire
The Buick Regal Sportback, like many contemporary cars, opts for a tire inflator kit rather than a traditional spare tire to save weight and increase cargo space. The inflator kit includes a tire sealant and an air compressor to temporarily fix a punctured tire until it can be properly replaced. However, if a spare tire is desired, it is available as an optional extra or aftermarket purchase. The specific spare tire size for the Buick Regal Sportback may vary depending on the year and model of the car, but many use a compact temporary spare tire of size T125/70D17.
Buick Regal Sportback models manufactured from 2018 to 2020 have tires with overall diameter ranging from 26.7" to 26.8", 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 Sportback years and trims.
Listed below are compact spare tire sizes that can fit some Buick Regal Sportback vehicles based on acceptable tire diameter range of 25.9" to 27.6". Some Regal Sportback models may require the use of a traditional full-size tire as a spare.
