Cadillac CTS Wheels and Rims

Cadillac CTS Aftermarket Wheel Fitment

The Cadillac CTS is the mid-size luxury sedan that anchored Cadillac's modern rear-drive era from 2003 through 2019 and the direct predecessor to the CT5. Element Wheels measures the CTS across three chassis platforms: the 1st gen Sigma Sedan (2003-2007), the 2nd gen Sigma Sedan and Coupe (2008-2014), and the 3rd gen Alpha Sedan including the Vsport trim (2014-2020). The bolt pattern is the trap here. The 1st gen ran 5x115 with a 70.3mm hub bore. Every CTS from 2008 forward moved to 5x120 with a 66.9mm hub bore. The two patterns sit only 5mm apart but they are not interchangeable. This page covers the standard CTS line; the performance CTS-V is a separate hub at /wheels/cadillac/cts-v with different Brembo brake hardware and a 1st gen CTS-V (2004-2007) running a 6-lug 6x115 pattern that does not appear anywhere else on the standard CTS line.

Find Your Cadillac CTS Generation

Pick your chassis to see wheels and rims that fit your specific CTS. The first thing to confirm is bolt pattern. The 2003-2007 1st gen Sedan is 5x115; everything from 2008 forward is 5x120. Within the 5x120 era, the 2nd gen Sigma Sedan, 2nd gen CTS Coupe, 3rd gen Alpha Sedan, and 3rd gen Vsport each carry their own measured offset window.

The Cadillac CTS Bolt Pattern Has Changed Once

The standard CTS has run two bolt patterns across three generations. The 1st gen Sedan (2003-2007), built on the Sigma platform, used 5x115 with a 70.3mm hub bore. Starting with the 2008 model year, when Cadillac refreshed the CTS on the updated Sigma platform, the entire line moved to 5x120 with a 66.9mm hub bore. Every 2nd gen Sedan, every 2nd gen Coupe, every 3rd gen Sedan, and every 3rd gen Vsport from 2008 through the end of production in 2019 uses 5x120 / 66.9mm.

5x115 and 5x120 are not interchangeable. They sit only 5mm apart, but the lug studs do not line up on a five-stud pattern at that spacing, and forcing a 5x115 wheel onto a 5x120 hub (or the reverse) will not seat. 5x115 also appears on some other GM platforms of the same era (the Impala, the Pontiac G6, the Buick Lucerne); 5x120 is shared with the 2009-and-newer CTS-V, the CT5, the CT5-V, and the modern GM rear-drive performance line. Lug count is identical at five, so confirm bolt pattern by the year, not by visual count. Wheels do not bolt across the 2007-to-2008 transition.

The CTS line was discontinued after the 2019 model year. Cadillac replaced the CTS with the CT5 for 2020 and forward, and the modern performance variant is the CT5-V (and the higher-output CT5-V Blackwing). The CT5 carries the same 5x120 / 66.9mm spec as the later CTS but the offset window and brake hardware are different. CT5 fitment lives at /wheels/cadillac/ct5. The performance CTS-V is on a separate hub with its own brake-driven fitment notes, including the 1st gen CTS-V (2004-2007) running a 6-lug 6x115 pattern that does not appear on any standard CTS.

Why CTS Generation and Trim Determine Wheel Fit

Inside the 5x120 era, the CTS splits into four chassis we measure separately. The 2nd gen Sedan ran from 2008 to 2013 and was offered in rear-wheel drive and all-wheel drive; the RWD car accepts a mild stagger as an aftermarket option while the AWD car is a square fitment by default. The 2nd gen Coupe (2011-2014) is a wider-track derivative that runs different rear wheel widths and a reversed offset window on the rear axle. The 3rd gen Sedan moved onto the Alpha platform for 2014 and added a Vsport trim with the twin-turbo V6 and beefier hardware. The 3rd gen Sedan also accepts mild stagger as an aftermarket option; the 3rd gen Sedan AWD is square. The Vsport carries a noted tall rear axle stub that affects how the wheel seats on the rear hub.

How We Confirm Fitment on Cadillac CTS Wheels

Element Wheels measures fitment on the platforms we sell wheels for, including every standard CTS generation from the 2003 Sigma Sedan through the 2019 Alpha Sedan and Vsport. For the CTS that means clearance from the wheel to the fender, gap between the back of the wheel and the suspension, brake caliper height on the base, premium, and Vsport packages, hub bore confirmation on both 70.3mm (1st gen) and 66.9mm (2nd-3rd gen) hubs, lug seat geometry across the 5x115-to-5x120 transition, axle-stub height on the 3rd gen Vsport, and the wider-rear-track offset window on the 2nd gen Coupe. 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.

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.
