What is the tire model of the Audi A4L?
2 Answers
The Audi A4L comes with three tire sizes: 225/50R17, 245/40R18, and 245/35R19. The first numbers, 225 and 245, represent the tire width in millimeters (225mm and 245mm, respectively). The numbers 50, 40, and 35 indicate the aspect ratio of the tire's cross-section, which is 50%, 40%, and 35% respectively—meaning the height of the cross-section is 50%, 40%, or 35% of the tire's width. The numbers 17, 18, and 19 represent the rim diameter in inches. The middle letters or symbols have special meanings: "X" denotes a high-pressure tire; "R" and "Z" indicate radial tires; and "—" signifies a low-pressure tire. The Audi A4L uses Dunlop tires. If you want to replace the tires yourself, follow these steps: Retrieve the spare tire and jack. Position the jack under the vehicle frame near the tire you wish to replace, ensuring it contacts the metal part of the frame. Raise the jack until it supports the car. The jack should be positioned under the vehicle, and you should check to ensure it is perpendicular to the ground. Remove the hubcap and loosen the nuts counterclockwise. Do not fully remove them—just enough to eliminate resistance. Keeping the tire on the ground when initially loosening the nuts ensures you turn the nuts, not the tire. Continue turning the nuts counterclockwise until they are loose. Repeat this step for all lug nuts, then fully remove them. Place the new tire onto 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 certified speed ratings ranging 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, facilitating practical use. For example: Standard rim 5.00F.
I used to work at an Audi 4S dealership and interacted with many A4L owners who frequently asked about tire specifications. Common tire sizes for the Audi A4L include standard configurations like 225/50 R17 and 245/40 R18, depending on the year and specific model. For example, the 2019 Sport Edition often comes with the latter. From my test-driving experience, tire size affects both comfort and fuel consumption—wider tires offer better grip but consume more fuel. I recommend checking the label on the door frame or the owner’s manual to confirm the factory specifications. Regular wear inspection is crucial, and avoid changing sizes arbitrarily as it can impact ABS and steering. When buying a used car, ensure the tires match—don’t just judge by appearance; safety comes first. Detailed data is often shared on Audi forums online, which I frequently reference for insights. For tire replacements, brands like Michelin or Bridgestone offer good value for money. In short, though tires may seem small, they significantly impact driving experience—don’t overlook them.
