2019 Cadillac CT6 Base Wheel Fitment Guide — What Works & What to Avoid
Your 2019 Cadillac CT6 Base uses a 5x120 bolt pattern and rolls on an 18x8 wheel with 48 millimeters of offset from the factory. You can upgrade to 19 or 20-inch wheels in widths from 7.5 to 8.5 inches, or step up to 22-inch wheels in 8-inch width. Since this vehicle runs a square setup front and rear, your wheel choice remains consistent across all four corners.
Keep in mind that only the 5x120 bolt pattern will fit your CT6—no other patterns work on this vehicle. The hub bore measures 66.9 millimeters; if your wheel's center bore is larger, install hub-centric rings to ensure a proper fit. Aggressive offsets or extremely wide wheels risk contact with the fender or suspension components, so stay within the compatible sizing we've listed to avoid clearance issues.
All our wheels bolt directly onto your CT6 and ship free throughout the lower 48 states. Heritage Wheel, Work Wheels, OHM, Aodhan, Petrol, KATANA RACING, Niche 1PC, and Enkei are all in stock and ready to ship today.
