What is the tire specification of the Cadillac ATS-L?
2 Answers
The tire specifications of the Cadillac ATS-L are 225/45R17 and 225/40R18. Taking 225/45R17 as an example, 225 indicates the tire width is 225mm, the aspect ratio is 45, R stands for radial tire, and 17 means the tire can be mounted on a 17-inch wheel rim. Tires are circular elastic rubber products assembled on various vehicles or machinery, mounted on metal wheel rims to support the vehicle body, cushion external impacts, achieve contact with the road surface, and ensure the vehicle's driving performance. The maintenance methods for tires are: 1. Regularly clean stones from the tire treads; 2. Avoid exposing tires to direct sunlight; 3. Frequently check tire pressure—refer to the normal tire pressure values listed inside the fuel tank cap and adjust accordingly; 4. Pay attention to suspension maintenance; 5. Periodically inspect the alignment of the front and rear wheels.
The tire specifications for my Cadillac ATS-L depend on the wheel size, with standard options being 17-inch or 18-inch. My car is the 18-inch version, with front tires sized 225/45 R18 and rear tires at 255/35 R18. This staggered setup (narrower front and wider rear) enhances steering response and rear-wheel-drive stability. Here, 225 indicates a tread width of 225mm, 45 is the aspect ratio (sidewall height percentage), and R18 denotes an 18-inch wheel diameter. In daily driving, this specification delivers sharper handling, especially noticeable during high-speed cornering where it feels exceptionally planted, though road imperfections are more pronounced. For the 17-inch variant, tires are typically 225/50 R17, offering a more comfortable ride suited for city commuting. Always adhere to factory specifications when selecting tires—never make arbitrary modifications, as this compromises safety and speedometer accuracy. For replacements, visit a professional shop to check tire pressure and balance.
