Cadillac ATS Tire Sizes & Rim Dimensions by Model Year and Trim
The Cadillac ATS offers a range of tire sizes and rim dimensions that vary by model year and trim level. Typically, rim widths range from 7 to 8 inches, while diameters commonly span from 17 to 19 inches. These variations accommodate performance and aesthetic preferences across trims such as the Luxury, Premium Luxury, and Performance models.\n\nFrom 2013 to 2019, standard trims generally feature 17-inch rims with all-season tires, while higher trims and sportier packages upgrade to 18 or 19-inch wheels with summer or performance tire options. Understanding tire size markings on sidewalls — for example, 235/45R17 — helps in identifying the tire width, aspect ratio, and rim diameter compatible with each ATS configuration.\n\nWhen comparing trims, note that wider rims allow for larger tire widths, improving grip and handling but may affect ride comfort. It's important to consult your specific model year and trim’s recommended tire sizes to ensure optimal performance and safety. Adjustments between trims can influence fuel efficiency and driving dynamics, so select tires and rims that align with your driving needs and style.
