Audi A4 Tire Sizes and Rim Dimensions by Model Year and Trim
The Audi A4 features a range of tire sizes and rim dimensions that vary according to model year and trim level. Common tire width, aspect ratio, and rim diameter combinations shift depending on the sportiness and equipment pack offered.\n\nTypical rim widths for the Audi A4 range from 7 to 8.5 inches, paired with diameters between 16 and 19 inches. Entry-level trims often use 16- or 17-inch wheels, while higher trims and sport editions adopt larger diameters and wider rims for improved handling.\n\nTo compare trims effectively, identify the tire size markings on your existing tires—found in a format like 225/50R17—where the numbers represent width (mm), aspect ratio (%), and rim diameter (inches). Matching these to manufacturer specifications for your model year ensures optimal fit and performance.\n\nAlways consult official Audi resources or a trusted tire professional to confirm compatibility, particularly when considering aftermarket wheels or tires differing from stock sizes.
