What other years of Cadillac CT4 have the same bolt pattern as the 2024?
The Cadillac CT4 uses the 5x115 pattern from 2020 through 2024. Wheels from any of these model years are dimensionally compatible with the 2024, provided the offset and center bore also match.
What is the center bore of a 2024 Cadillac CT4?
The factory center bore (hub bore) for the 2024 Cadillac CT4 is 70.3mm. If your aftermarket wheels have a larger hub bore, you will need hub-centric rings to prevent vibration.
