2021 Cadillac CT5 Sport Wheel Fitment Guide — What Works & What to Avoid
Your 2021 Cadillac CT5 Sport (which includes the V trim) uses a 5x120 bolt pattern. The factory setup runs 19x8.5 wheels at a 29mm offset. You can fit anything from 18-inch to 20-inch diameters, with widths ranging from 7.5 to 9.5 inches depending on size. Since this vehicle doesn't run staggered, square setups work perfectly and give you more flexibility.
Watch for the 66.9mm center bore on all wheels—if your choice has a larger bore, use hub-centric rings to ensure proper fitment. Only 5x120 patterns will bolt on safely. Going significantly wider or running aggressive negative offsets risks rubbing your fenders or suspension components, so stay close to the stock 29mm offset when possible.
Every wheel we offer for your CT5 Sport is guaranteed to bolt on, and we ship free throughout the lower 48 states. Heritage Wheel, Work Wheels, OHM, Aodhan, Petrol, KATANA RACING, Niche 1PC, and Enkei all have in-stock options ready to go.
