3 Answers
The Changan CS55 comes with two tire sizes: 17-inch and 18-inch, with specifications of 225/60R17 and 225/55R18 respectively. The tire model specifications are usually marked on the tire sidewall, displaying information such as tire size, aspect ratio, and tread width. The Changan CS55 is an SUV model launched by Changan Automobile, with body dimensions of 4500mm in length, 1855mm in width, and 1690mm in height. In terms of exterior design, the Changan CS55 features an obsidian star grille, a leaping wave diving body, a three-dimensional obsidian-style rear, LED "cool" lights, and offers "Dynamic Red" and "Starry Blue" as the main body colors along with high-tech configurations.
I've been driving the Changan CS55 for a while, and the original tire size is 225/55 R18. The 225 indicates the tire width in millimeters, 55 is the aspect ratio, and R18 refers to the rim diameter. This set of tires is paired with 18-inch alloy wheels, providing good stability for daily city driving with decent grip, and they don't feel floaty at high speeds. During rain or snow, it's especially important to maintain tire pressure around 2.3-2.4 bar—too high and the ride comfort suffers, too low and it can lead to skidding and increased fuel consumption. I personally check the wear every six months. If the tread wears down to the safety indicator, it's time to replace them promptly. Choosing original-size Michelin or Pirelli tires ensures better reliability and durability.
As someone who frequently works on car maintenance, the standard tire size for the Changan CS55 is 225/55 R18. The 225 represents the tire width, 55 is the aspect ratio height, and R18 indicates the rim size. This design balances both comfort and handling for an SUV, providing a quiet ride. It's recommended that owners check tire pressure every 5,000 kilometers. Unstable pressure can accelerate wear—keep it below 2.5 bar in summer and no lower than 2.2 bar in winter. When replacing tires, stick to the original size to ensure the speedometer and braking system function correctly, and avoid compromising safety for cheaper options.
