2 Answers
The tire model for the Q7 is 285/40R21. The first number 285 indicates the tire width is 285MM, 40 represents the aspect ratio of the tire section is 40%, meaning the section height is 40% of the width. The letter R stands for radial tire, and 21 denotes the rim diameter is 21 inches. The Q7 has a top speed of 220km/h, accelerates from 0-100km/h in 5.6 seconds, and has a fuel consumption of 3.8L per 100km. In addition to the model, tires are also marked with the following common data: Tire cord material: Represented 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 defined 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 specification compatible with the tire for practical use, such as "Standard rim 5.00F".
The tire specifications for the Audi Q7 typically vary depending on the year and configuration. Take the one I drive as an example—many standard models use 275/50 R20, which means a tire width of 275 millimeters, a sidewall height ratio of 50%, and 20-inch rims. I usually choose this setup because it strikes a balance between handling and comfort, providing stability during high-speed turns while maintaining clear road feedback. If you prefer off-roading or city commuting, you might opt for 19-inch rims with 255/55 R19 tires, which offer stronger grip. When replacing tires, I recommend visiting a professional shop to check the matching index, ensuring safety and normal fuel consumption—otherwise, issues may arise. Regularly checking tire pressure is also crucial, as it extends tire life and prevents accidents. Overall, the Q7's tire details are quite thoughtfully designed.
