The tire model specification is 255/50R20. The first number 255 represents the tire width of 255MM, 50 indicates the aspect ratio of the tire section is 50%, meaning the section height is 50% of the width, and 20 stands for the rim diameter of 20 inches. The middle letters or symbols have special meanings: "X" denotes high-pressure tires; "R" and "Z" represent radial tires; "—" indicates low-pressure tires. The fuel consumption per 100 kilometers is 5.3L. In addition to the model, the tire also displays the following common data: 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. 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 tires from 4.8km/h to 300km/h. Commonly used 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".
I've been driving the GAC GS8 for several years, and the original tire size is usually 235/55 R19. This specification is clearly visible on the sidewall of the tire. The 235 indicates the tire width of 235 millimeters, the 55 is the aspect ratio percentage, and R19 refers to the 19-inch wheel diameter. It performs quite stably, especially on highways where the grip is strong and there's no fear of slipping. When replacing tires, it's recommended to first take a photo to record the original model or check the user manual for confirmation. Don't casually switch to other sizes, as it can affect the accuracy of the speedometer and fuel consumption. I've tried Michelin tires of the same model and felt a slight improvement in comfort, though the original domestic tires are also durable. Checking tire pressure is crucial, as the right size ensures safe driving.
Having worked in car repairs for many years, I've seen numerous tire issues with the GS8. Common tire sizes are 235/55 R19 or 245/50 R20, depending on the version and year. The code 235/55 is simple to explain: the first two numbers represent the tire width in millimeters, the 55 after the slash indicates the height is 55% of the width, the R stands for radial construction, and 19 is the wheel diameter in inches. When replacing tires, it's essential to match the original specifications to avoid disrupting the vehicle's dynamic balance and increasing fuel consumption. The most reliable way to check is by looking at the sidewall markings, though sometimes the manual provides a backup reference—don't overlook it to prevent safety hazards. Incorrect tire sizes can lead to unstable steering or accelerated wear, so regular maintenance, including checking tire pressure and wear, is crucial.
