1The original tire model of the JAC Refine S3 is 205/55R16. The first number 205 represents the tire width of 205MM, 55 indicates 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 16 represents the rim diameter of 16 inches. The JAC Refine S3 has a top speed of 165km/h and a fuel consumption of 6.7L per 100km. 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 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 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 driven quite a few cars, including the JAC Refine S3, whose original tire size is usually 205/55 R16, a pretty common dimension. The 205 represents a tire width of 205 millimeters, 55 is the aspect ratio, meaning the tire's height is 55% of its width, and R16 indicates a 16-inch wheel diameter. This combination provides better grip and stability for the vehicle. The manufacturer chose this size mainly to enhance comfortable driving, especially by reducing bumps on city roads. When I took it on long trips, it did feel much steadier. However, tire specifications can vary by batch, and higher trim levels sometimes use different models. I recommend owners check their manuals to confirm and regularly inspect tire wear, replacing tires promptly for safe driving—don't wait until the risk of a blowout increases. After all, tires are crucial to overall vehicle performance. Checking tire pressure yourself is also simple; just maintain it at the standard value.

As an S3 owner, my car came with 205/55 R16 tires as standard, and they perform quite well. The 205 width provides sufficient grip, preventing instability at high speeds, while the 55 aspect ratio offers good cushioning over bumps. The R16 wheels also look stylish. The factory chose this size to balance handling and comfort, which is why I often use it to transport my family—it's quiet and safer. However, tire specifications may vary by model year; for example, some post-2020 models changed sizes, so always check the manual or inspect the wheels when buying. When it's time for new tires, sticking with the original factory model is cost-effective—avoid cheap knockoffs that wear out quickly. During routine maintenance, have the mechanic check tread depth; safety comes first. I've learned a simple way to remember this sizing notation: the numbers indicate width, aspect ratio, and rim size in sequence.

I prioritize driving safety. The JAC Refine S3's original tires are mostly equipped with the 205/55 R16 specification, which represents 205mm width, 55% aspect ratio, and 16-inch rims. The original design chose this size to ensure stable braking and grip, preventing skidding accidents. Mismatched tires can cause accidents—I previously checked the manual to confirm my car uses exactly this size. I recommend fellow drivers regularly check tire pressure and wear. Replace tires promptly if they age quickly; don't skimp on this expense. Wrong specifications (e.g., insufficient width) compromise handling. Original specs may vary slightly by configuration (some use high-performance low-profile tires), but the key is maintaining uniform maintenance for peace of mind—safety is no trivial matter. The size numbering is simple: the first digit indicates width, the middle is aspect ratio, and the last denotes rim size.
