The original tire configuration model for the CS75 is 225/55R19. The first number 225 indicates the tire width is 225MM, 55 represents the aspect ratio of the tire section is 55%, meaning the section height is 55% of the width. The letter R stands for radial tire, and 19 denotes the rim diameter is 19 inches. The CS75 has a fuel consumption of 6.5L per 100 kilometers. In addition to the model, the following common data is also marked on the tire: Tire cord material: Indicated by Chinese pinyin, such as M-cotton cord, R-rayon cord, N-nylon cord, G-steel cord, ZG-steel radial cord tire. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under specified conditions. Letters A to Z represent the certified speed ratings of the tire 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 specification compatible with the tire for practical use, such as "Standard rim 5.00F".

The tire model of the Changan CS75 is typically 225/65 R17, indicating a tire width of 225 millimeters, a height that is 65% of the width, and suitable for 17-inch rims. This size design balances off-road capability and urban driving comfort. As I often see in repair shops, many car owners choose it because it is affordable and durable. When replacing, it is recommended to stick to the original factory specifications to avoid affecting steering or fuel consumption. Different year configurations may upgrade to 225/60 R18, such as the 2023 model equipped with larger rims to enhance handling. Remember to check the tire pressure monthly, maintaining it at 2.3 bar, and replace the tires promptly when the tread is shallow—never drive with worn-out tires.

I've been driving the CS75 for two years with standard 225/65 R17 tires. Just last week, I spent over 1000 yuan at the auto parts market for a new set, and the car feels much more stable now. Previously, I didn't pay attention to tire pressure on bumpy roads, which caused severe side wear. Later, I learned to regularly check tread depth and pressure indicators. This size works well for SUVs on highways—quiet with good wet traction. Opting for a reputable brand like Goodyear makes daily maintenance easier. Just remember to replace them before exceeding 60,000 kilometers.

When it comes to the CS75 tires, the original factory specification is typically 225/65 R17. I usually teach my friends to check the tread depth using a one-yuan coin: if the coin can't cover the letters, it's time to replace them. The optimal tire pressure should be maintained at 2.3 bar; too low increases fuel consumption, while too high risks a blowout. Don't compromise by using different sizes when replacing tires, as the wheel size affects overall balance. Regular tire rotation extends their lifespan, recommended every 8,000 kilometers.
