What is the tire size of the CS75?
2 Answers
The CS75 has three tire size specifications: 225/55R19, 225/60R18, and 225/65R17. For 225/55R19, the first number 225 represents the tire width of 225MM, 55 indicates the aspect ratio of the tire section is 55% (i.e., the section height is 55% of the width), and 19 denotes the rim diameter of 19 inches. The letter "R" in the middle stands for radial tire. For 225/60R18, the first number 225 represents the tire width of 225MM, 60 indicates the aspect ratio of the tire section is 60% (i.e., the section height is 60% of the width), and 18 denotes the rim diameter of 18 inches. The letter "R" in the middle stands for radial tire. For 225/65R17, the first number 225 represents the tire width of 225MM, 65 indicates the aspect ratio of the tire section is 65% (i.e., the section height is 65% of the width), and 17 denotes the rim diameter of 17 inches. The letter "R" in the middle stands for radial tire. The CS75 uses Yokohama tires with the tread pattern GEOLANDAR-G91. The wheel rims feature a sporty design with a dual-color finish. If you want to replace the tires yourself, follow these steps: Retrieve the spare tire and jack. Place the jack under the vehicle frame near the tire to be replaced, ensuring it touches the metal part of the frame. Raise the jack until it supports the car. The jack should be positioned under the vehicle, and ensure it is perpendicular to the ground. Remove the hubcap and loosen the nuts counterclockwise. Do not fully remove the nuts—just enough to eliminate resistance. Keeping the tire on the ground when loosening the nuts ensures the nuts turn, not the tire. Turn the nuts counterclockwise until they come off. Repeat this step for all lug nuts and remove them completely. Place the new tire on the wheel hub, carefully aligning the tire rim with the wheel bolts. Install the lug nuts and hand-tighten them until all nuts are snug. The tire replacement is now complete. In addition to the model, tires also display the following common data: Tire cord material: Indicated by Chinese pinyin, such as M for cotton cord, R for rayon cord, N for nylon cord, G for steel cord, and ZG for steel radial cord tires. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under defined conditions. Letters A to Z represent speed ratings from 4.8 km/h to 300 km/h. Common speed ratings include: Q: 160 km/h; H: 210 km/h; V: 240 km/h; W: 270 km/h; Y: 300 km/h. Rim specification: Indicates the rim size compatible with the tire for practical use, such as "Standard Rim 5.00F."
Back when I drove the Changan CS75, the tire size was 225/65 R17, which was the standard configuration. The salesperson confirmed this with me when I purchased the car. The tire width is 225 millimeters, the 65 indicates the aspect ratio, and it's mounted on 17-inch rims. This size provides good stability, whether driving in the city or on the highway. However, be cautious about upgrading too casually—for instance, switching to larger rims might look better but could increase fuel consumption and put extra strain on the suspension. I used to check the tire pressure weekly and replace them promptly when worn. I recommend checking your vehicle's manual, as specific models might have slight variations in size. When replacing tires, it's safer to visit a professional shop that matches the original factory specifications. Don't skimp on cheap, low-quality tires—safe driving is what matters most. Also, the tire size affects wet-weather performance, and the factory design works well for drainage.
