Cadillac CT5 Spare Tire
The Cadillac CT5 comes equipped with a compact spare tire for emergency use. This tire is a temporal solution that is designed for occasional use and at reduced speeds. It is smaller in size and width compared with the regular tires on the CT5, whose tire size ranges between 17-19 inches, depending on the model. The spare tire functions as a temporary replacement that can cover short distances until the damaged tire is repaired or replaced. It is important for Cadillac CT5 owners to note the warning labels on the spare tire, as they provide information about the maximum speed and duration that the spare tire should be used, to ensure safety.
Cadillac CT5 models manufactured from 2020 to 2025 have tires with overall diameter ranging from 26.6" to 27", 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 CT5 years and trims.
