Cadillac CTS I Tire Sizes, Rim Widths & Trim Guide by Model Year

The Cadillac CTS I, produced from 2003 to 2007, features varying tire sizes and rim measurements across its trims and model years. Common tire sizes range from 225/55R16 to 255/40R18, with rim widths typically between 7 to 8.5 inches.\n\nBase models often come equipped with 16-inch rims, while sportier trims like the CTS-V use wider 18-inch rims to accommodate larger tires. Understanding the tire size markings is key: the first number indicates tire width in millimeters, followed by the aspect ratio, and then the rim diameter in inches.\n\nWhen comparing trims, note that rim widths increase with performance-focused packages, impacting the tire profile for better handling. Always verify the exact tire specifications for your specific model year and trim to ensure proper fitment and safety.\n\nRegularly checking your Cadillac CTS I's tire size markings and rim dimensions will help maintain optimal driving performance, comfort, and tire longevity.
