Cadillac STS Spare Tire
The Cadillac STS, a luxury mid-sized sedan, is often equipped with a compact or donut spare tire to be utilized in the event of a tire failure. These temporary spare tires, typically smaller and narrower than regular tires, are designed to save both space and weight, and hence are stored in the trunk of the car. The exact size of the Cadillac STS's spare tire depends on the year and model of the car, but many versions have a temporary spare tire size of T125/70R16. However, it's vital to remember that these spare tires are not meant for long-term use, as they're not as durable or stable as regular tires, and should be replaced as soon as possible.
Cadillac STS models manufactured from 2005 to 2011 have tires with overall diameter ranging from 26.3" 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 Cadillac STS years and trims.
Listed below are compact spare tire sizes that can fit some Cadillac STS vehicles based on acceptable tire diameter range of 25.5" to 28.1". Some STS 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 Cadillac STS spare tire size designated by vehicle's manufacturer.
