Cadillac CT4 Spare Tire Sizes

The Cadillac CT4 has used a 5x115mm bolt pattern for all models from 2020 to 2021 along with tire diameters ranging from 25.0" to 25.4" 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 CT4 years and options. In this case, a 125/80R17 temporary spare tire is the recommendation for all applications.
