The tire model for the Audi A4 is 245/40R18. The first number, 245, indicates the tire width is 245MM. The 40 represents the aspect ratio of the tire's cross-section, which is 40%, meaning the height of the cross-section is 40% of the width. The letter R stands for radial tire, and 18 denotes the rim diameter is 18 inches. The Audi A4 has a top speed of 220km/h, accelerates from 0 to 100km/h in 3.1 seconds, and has a fuel consumption of 3.6L per 100km. 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 tire. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under specified conditions. Letters A to Z represent certified speed ratings 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: Shows the rim size compatible with the tire for practical use, such as "Standard Rim 5.00F".
As an automotive enthusiast, I've driven quite a few Audi A4s, and their most common tire specification is 225/50 R17. The exact model may vary slightly depending on the model year, for example, the 2022 base version commonly uses this size. The 225 indicates a tread width of 225 millimeters, the 50 is the aspect ratio meaning the sidewall height accounts for 50%, and R17 refers to a 17-inch rim diameter. Choosing the right tires is crucial because mismatched ones can lead to reduced grip, unstable handling, and even higher fuel consumption. I recommend that owners refer to their vehicle manual or door jamb label to confirm the factory specifications, regularly check tire pressure and wear, which can prevent safety hazards like skidding. When replacing tires, have them installed at a reputable shop, brands like Michelin or Bridgestone perform consistently well, and avoid randomly buying cheap ones online.
