Cadillac CT5 Wheels and Rims

Cadillac CT5 Aftermarket Wheel Fitment

The Cadillac CT5 is the mid-size luxury sedan that launched for the 2020 model year as the replacement for the CTS. It rides on the GM Alpha 2 platform with 5x120 bolt pattern and a 66.9mm hub bore across every configuration we measure. The standard CT5 carries four catalog rows on this hub: RWD with Base Brakes, RWD with Sport Brakes, AWD with Base Brakes, and AWD with Sport Brakes. The RWD trims accept optional staggered fitment. The AWD trims run square (same wheel and tire all four corners) so the all-wheel-drive system can rotate tires evenly. The CT5-V and CT5-V Blackwing performance trims live on their own hub at /wheels/cadillac/ct5-v. The smaller CT4 sedan, also on Alpha 2, has its own fitment encyclopedia at /wheels/cadillac/ct4. The predecessor CTS sedan is documented at /wheels/cadillac/cts. Element Wheels measures fitment on every CT5 configuration separately.

Find Your Cadillac CT5 Configuration

Pick your drivetrain and brake package to see wheels and rims that fit your specific CT5. Bolt pattern stays 5x120 / 66.9mm CB across all four configurations. What changes is the rear width window (RWD takes wider rears, AWD stays square front-to-rear) and the front wheel-face clearance (Sport Brakes carry a bigger caliper than Base Brakes).

The Cadillac CT5 Bolt Pattern

Every Cadillac CT5 uses 5x120 with a 66.9mm hub bore. That covers all four configurations in our catalog: RWD with Base Brakes, RWD with Sport Brakes, AWD with Base Brakes, and AWD with Sport Brakes (2020 and up). The 5x120 pattern is shared across the GM Alpha 2 sedans, so the CT5 wheel spec sits in the same bolt-pattern family as the CT5-V and CT5-V Blackwing performance trims. The 66.9mm Cadillac hub bore is its own spec. It does not match the BMW 5x120 hub bore (72.56mm) or the Lexus LS 5x120 hub bore (60.1mm), so wheels sized for those platforms will need a hub centric ring to fit a CT5 correctly.

The predecessor to the CT5 is the Cadillac CTS, which ran across three generations from 2003 through 2019. The 2nd gen (2008-2014) and 3rd gen (2014-2019) CTS also used 5x120 with a 66.9mm hub bore, so CTS wheels of that vintage can sometimes carry over to a CT5, but the offset windows are different and the CT5 chassis geometry is different enough that a wheel that sat right on a 2014 CTS will not always sit right on a CT5. The 1st gen CTS (2003-2007) ran 5x115 and does NOT fit a CT5. The CT4 sedan, also on Alpha 2 in our catalog, runs 5x115 (inherited from the ATS) on the standard CT4 and CT4-V rows, with a 5x120 spec on the CT4-V Blackwing only. CT4 and CT5 do not cross at the bolt pattern. Compare across the rest of the Cadillac lineup at our Cadillac wheels and rims hub.

Why RWD vs AWD and the Brake Package Matter

The four CT5 configurations split on two axes: drivetrain (RWD or AWD) and brake package (Base Brakes or Sport Brakes). All four share the 5x120 bolt pattern and the 66.9mm hub bore. The wheel windows differ. The RWD CT5 accepts optional staggered fitment in our window. A wider rear wheel and tire (up to 10.5 inch in our aftermarket width range) helps the rear axle put down power on a rear-drive luxury sedan. The AWD CT5 is square only. The all-wheel-drive system asks for the same wheel and tire on every corner so the front and rear axles can rotate together. We do not recommend staggered fitment on an AWD CT5.

Brake package matters separately. The Sport Brakes option carries a bigger front caliper than the Base Brakes setup. Bolt pattern stays the same on both, but specific wheel faces that clear the Base Brake setup do not always clear the Sport Brake caliper. We measure both brake variants on the car. If your CT5 has Sport Brakes, confirm wheel face clearance before ordering. The CT5-V and CT5-V Blackwing performance trims carry their own larger brake packages and are documented separately on the CT5-V hub.

Every wheel we recommend is backed by our Fitment Guarantee. If a wheel does not fit, we pick up the wheels and refund 100 percent. No risk to you.

How We Confirm Fitment on Cadillac CT5 Wheels

Element Wheels measures fitment on the platforms we sell wheels for, including every CT5 configuration. For the CT5 that means clearance from the wheel to the fender, gap between the back of the wheel and the suspension, front brake caliper height (Base or Sport), hub bore confirmation to the 66.9mm Cadillac hub, lug seat geometry, and turning clearance. At our fitment facility in Chandler, Arizona, the Element Wheels team measures directly on the physical platforms we support. We don't pull specs from manufacturer sheets the way most retailers do. That measurement work is what produced the four-row trim split on this page.
