Cadillac CT5 Spare Tire Sizes

The Cadillac CT5 has used a 5x120mm bolt pattern for all models from 2020 to 2023 along with tire diameters ranging from 26.7" to 27.0" tall. Using a temporary spare tire with a diameter close to the standard tire has many benefits, especially for modern vehicles with larger brake calipers and anti-lock brakes or traction control systems. Tire diameter as well as wheel diameter clearance have been taken into account for the specific Cadillac CT5 years and options. In this case, a 145/60R20 temporary spare tire is the recommendation for all applications.
