Cadillac CTS Spare Tire

The Cadillac CTS typically comes equipped with a compact or mini spare tire, also known as a "doughnut" tire, which is smaller than the regular tires and only intended for temporary emergency use until the damaged tire can be properly repaired or replaced. This mini spare tire is usually concealed in the trunk space in a dedicated well or compartment, and it should be used only for limited distances at reduced speeds, as advised in the vehicle's instruction manual. The recommended spare tire size varies depending on the model and year of the Cadillac CTS, but a common size for many models is T135/70R18, implying a radial construction with a width of 135mm, a sidewall aspect ratio of 70%, and a wheel diameter of 18 inches. Always verify the appropriate type and size of spare tire for a specific vehicle with the manufacturer's specifications or a trusted tire supplier.

Cadillac CTS models manufactured from 2003 to 2019 have tires with overall diameter ranging from 25.7" to 27.7", 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 CTS years and trims.

Listed below are compact spare tire sizes that can fit some Cadillac CTS vehicles based on acceptable tire diameter range of 24.9" to 28.5". Some CTS 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 CTS spare tire size designated by vehicle's manufacturer.
