2020 represents the first model year for the all-new Cadillac CT4 compact luxury sedan. In fact, the CT4 represents the first time that Cadillac has competed in the luxury sedan C-segment in North America. The all-new sedan is based on the award-winning, rear-wheel-drive-based Alpha II platform and features a set of new turbocharged engines, available Super Cruise, 12 exterior color options, and 8 total wheel sets. That last bit – the Cadillac CT4 wheel options – is what we’re going to focus on today.
We’ve taken the liberty of compiling a comprehensive guide to 2020 Cadillac CT4 wheels, complete with pictures, availability info, and other details.
All 2020 Cadillac CT4 wheels are made of alloy aluminum, range from 17- to 19-inches in diameter, and vary in design, width, and finish. Of the eight wheel choices, three are standard wheels, another three are available factory upgrades, and two are LPO-level (accessory) options. Notably, all Cadillac LPO-level wheels are installed at the factory, meaning that the vehicles arrive at dealer lots with the optional wheels already installed.
It should also be noted that wheel availability varies by trim level. The entry-level Luxury model is fitted with standard 17-inch wheels, while all other trim levels are equipped with 18-inch wheels. Meanwhile, the two LPO-level 19-inch-wheel options are available on all trim levels.
All 2020 CT4 wheels available from the factory are shown above, along with the corresponding RPO code. Meanwhile, the table below lists the 8 sets of 2020 CT4 wheels, along with the corresponding RPO Codes, diameters, widths, finishes, and trim level availability.

|SGV||19||N/A||Multi-Spoke||Polished w/ Dark Android Gloss||All models (LPO)|

We should also note that all CT4 models come with either a self-sealing or run-flat tire, and therefore do not feature a spare wheel.
The GM Authority Take
Cadillac offers a fairly decent range of wheel options from the factory, and if we may interject a bit of subjectivity, we’d say the brand has done a fantastic job of creating designs that are bold yet tasteful. In fact, this isn’t exclusive the the 2020 Cadillac CT4 wheels, but is instead consistent across the entire Cadillac lineup.
Additionally, we’re patiently awaiting the reveal of the upcoming CT4-V Blackwing model, which will flaunt an exclusive set of wheels, which we’ll share with you as soon as they’re available – so be sure to subscribe to GM Authority for more Cadillac CT4 news, Cadillac news, and around-the-clock GM news coverage.
