What is the maximum wheel size that can be upgraded for an Audi A6?
2 Answers
Audi A6 wheels can be upgraded to a maximum size of 225-45r18. Generally, wheel upgrades do not exceed a few inches in size. For example, if the original wheels are 205-55r16, they can be upgraded to 225-45r18, as long as the wheels do not rub against the inner fender when turning. Impact of increasing wheel size: The vehicle's mileage will also decrease because the mileage is calculated based on the number of wheel rotations, which may affect the judgment of maintenance intervals. Applicable range of tires and rims: Tires generally have an applicable range for rims, meaning that each tire size can fit rims with slightly varying widths. This is often specifically noted in the tire tread manual. Additionally, different brands of tires, even with the same model number, may have different standard rim widths.
The maximum size for Audi A6 wheel modifications isn't fixed—it depends on your specific model and year. Having modified many cars for friends, I've found A6 OEM wheels typically range from 17 to 20 inches. While upgrading to 21 or 22 inches is possible, critical factors must be considered: ensure sufficient fender clearance to prevent tire rub during turns (which could cause accidents), and inspect the braking system—larger wheels may require upgraded rotors to avoid extended stopping distances. Lower tire aspect ratios increase blowout risks, especially on poor roads. Legally, regional restrictions vary (e.g., excessive protrusion may violate regulations and void insurance claims). Always consult a professional shop for custom measurements pre-modification, then test high-speed stability post-installation. Prioritize safety over size—larger wheels significantly reduce comfort and increase bumpiness.
