Difference

A 145/60R20 spare size is within the accepted tolerance range for temporary use with all OEM tire diameters for this Cadillac generation.
The overall tire height (not the wheel size) is the consideration for the spare tire fitment. The 20" spare wheel is then chosen for proper fitment and not interfere with the brake or suspension system. This is regardless of the OEM wheel option that came on the vehicle.
Frequently Asked Questions
Some CT5-V vehicles from these years vary in appearance, will this spare work for mine? Yes. The redesign in 2025 only affected appearance and has no bearing on the spare tire. If the CT5-V version matches yours, this is correct.
Note: This compact spare tire is intended only to be used temporarily in the event of a flat tire. This spare permits drivers to continue their travels to their destination or to a service provider to repair or replace the vehicle’s damaged tire.
