The original tire specifications for the ATS-L are as follows: front and rear tire specifications include 225/40R18, 255/35R18, and 225/45R17. The ATS-L is equipped with the Bridgestone Potenza RE050A series tires, which focus on sportiness. The entire lineup does not come with a spare tire. The ATS-L is a mid-size car under SAIC-GM Cadillac, with dimensions of 4730 mm in length, 1824 mm in width, and 1426 mm in height, and a wheelbase of 2860 mm. In terms of exterior design, the car features many muscular lines on the hood and sides, showcasing a robust appearance. For the interior, the ATS-L's cabin design is rich in brand characteristics, with the layout of the center console buttons resembling the brand logo. Extensive use of piano black finish and leather-wrapped interior significantly enhances the ATS-L's interior quality.
I'm quite familiar with the original tire specifications of the Cadillac ATS-L, which are typically 235/45 R17. This refers to a tread width of 235 millimeters, an aspect ratio of 45%, corresponding to 17-inch wheels. When driving, I always feel that this specification is very well balanced, providing excellent stability and grip, especially when turning on city roads—it's very comfortable and not prone to slipping. The original tire setup is crucial because it matches the vehicle's overall performance tuning, including the suspension and drivetrain. If replacement is needed, I recommend choosing the same size from reputable brands and not blindly upgrading the size, as it may affect handling and even fuel consumption. Regularly checking tire pressure and wear condition is also essential to avoid sudden risks and extend service life. The quality of original tires is generally more reliable, giving me a sense of security in daily driving.
As someone who has driven similar cars for years, I recall that the Cadillac ATS-L originally came equipped with 235/45 R17 tires. In these numbers, the first represents width, the second is the aspect ratio, and the third is the wheel diameter. The factory-fitted size handles road imperfections well, making long-distance driving less bumpy. For maintenance, I often advise beginners to use a mobile app to record tire pressure and check it monthly—it's safe and hassle-free. When replacing tires, always refer to the manual's recommendations; don't cheap out and switch to different sizes, as it may worsen handling or increase fuel consumption. Before winter driving, it's best to check the tread depth—if it's severely worn, losing control on icy or snowy roads becomes more likely. The original tires' durability is generally good, lasting around 40,000 to 50,000 kilometers without issues.
