3 Answers
The tire model of the Cadillac ATS-L is 225/45R17. The first number 225 represents the tire width of 225MM, 45 indicates the aspect ratio of the tire section is 45%, meaning the section height is 45% of the width, and 17 stands for the rim diameter of 17 inches. The middle letters or symbols have special meanings: "X" denotes high-pressure tires; "R" and "Z" indicate radial tires; "-" represents low-pressure tires. The Cadillac ATS-L has a top speed of 215km/h, accelerates from 0-100km/h in 7.2 seconds, and has a fuel consumption of 6.8L per 100km. In addition to the model, tires are marked with the following common data: Tire cord material: Represented by Chinese pinyin, such as M-cotton cord, R-rayon cord, N-nylon cord, G-steel cord, ZG-steel radial cord. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under defined conditions. Letters A to Z represent certified speed ratings from 4.8km/h to 300km/h. Common speed ratings include: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h. Rim specification: Indicates the rim size compatible with the tire for practical use, such as "Standard Rim 5.00F".
I've been driving a Cadillac ATSL for three years. This model comes with two types of original tires: the configurations for 17-inch and 18-inch rims are different. The 17-inch version is equipped with 225/45 R17 tires, which I find quite comfortable for city driving with minimal road noise. For the 18-inch luxury version, the front tires are 225/40 R18, while the rear tires are wider at 255/35 R18, offering significantly better grip and much more stability when cornering in the rain. I recommend checking the markings on the side of your tires for the most accurate information, as the specific model numbers are engraved there. Always double-check the parameters when changing tires—last time, a friend of mine got the wrong specifications, which even messed up the speedometer. Regular maintenance checks on tire pressure and wear are also crucial, especially since the price difference between different tire specifications can be several hundred yuan.
As a technician who frequently handles Cadillac repairs, I've found that ATSL owners most commonly inquire about tire specifications. Depending on the factory configuration, this vehicle comes with 17-inch wheels paired with 225/45 R17 single-size tires, while the 18-inch sport version uses a combination of 225/40 R18 front tires and 255/35 R18 rear tires. The wider rear tire setup enhances cornering stability, but it's crucial to avoid mixing front and rear tires. We recommend performing a wheel alignment every 10,000 kilometers, especially if frequently driving on rough roads, as uneven wear can lead to sudden increases in tire noise. When replacing tires, besides checking the size, pay attention to the manufacturing date - tires stored for over three years will have hardened rubber.
