Cadillac CT6 Spare Tires
The Cadillac CT6 used a 5x120 mm bolt pattern for all models from 2016 to 2020 along with tire diameters ranging from 27.3" to 27.7" tall. Using a temporary compact 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.
The tire diameter and the wheel diameter clearance have been taken into account for the specific Cadillac CT6 years and options. In this case, a 145/60R20 temporary spare tire is the recommendation for all applications. We've provided a breakdown by vehicle generation and model specifics to help you find the correct Cadillac CT6 spare tire.
