2021 Cadillac CT4 Sport Wheel Fitment Guide — What Works & What to Avoid
Your 2021 Cadillac CT4 Sport (including V trim) uses a 5x115 bolt pattern with a 70.3mm hub bore. The factory wheel is 18x8 at 35mm offset. You can go up to 20 inches, choosing from sizes like 17x7.5, 18x8.5, 19x8, or 20x8.5. The car runs a square setup, so all four wheels match in width and offset.
Keep in mind that only 5x115 bolts will fit this Cadillac—no other pattern works. Since your hub bore measures 70.3mm, use hub-centric rings if your wheel's center bore is larger, ensuring a proper seat. Aggressive offsets or excessive widths risk contact with fenders or suspension components, so stick within the compatible sizes listed.
Every wheel we offer for your CT4 Sport is confirmed to fit and ships free throughout the lower 48 states. Browse Heritage Wheel, Petrol, American Racing, Performance Replicas, and other top brands—all in stock and ready to ship.
