The 2020 Cadillac CT4 is the luxury brand’s first entry into the compact luxury sedan segment (C-segment) in North America. The new sedan is based on the Alpha II platform, the successor to the Alpha I architecture that was initially introduced with the 2013 Cadillac ATS. For the 2020 model year, a total of eight different Cadillac CT4 wheel options are available from the factory, which we will cover extensively today.
All of the 2020 Cadillac CT4 wheels are made of aluminum alloy and range from 17 to 19 inches in diameter. They all have different designs, widths, and finishes to suit different tastes. Three of the wheels are standard, three are available as factory upgrades, and the last two are accessory options (aka LPO-level items). Even the LPO-level wheels will be installed at the factory, so the cars will arrive at dealerships with the wheels already installed.
Availability of the different wheel diameters varies by trim level. For instance, the entry-level Luxury model is fitted with standard 17-inch wheels, while all other trim levels feature 18-inch wheels. Meanwhile, the two LPO-level 19-inch-wheel options are available across all trim levels – Luxury, Premium Luxury and Sport.
