Audi A6 Avant (4G5, C7, 4GD) Tire Size & Rim Dimensions Guide

The Audi A6 Avant (4G5, C7, 4GD) features a range of tire sizes that vary by model year and trim level. Common tire markings include widths from 225 to 265 mm, aspect ratios between 40 and 55, and rim diameters typically ranging from 17 to 20 inches.\n\nTrim-specific differences often affect rim width and diameter. For example, higher trims may use wider rims (up to 9.0 inches) and larger diameters to accommodate sportier tires, improving handling and aesthetics. It's essential to verify tire codes such as 245/45 R18 or 255/40 R19 based on your vehicle’s production year and trim.\n\nWhen comparing trims, consider that an increase in rim diameter usually requires lower profile tires to maintain the correct overall diameter, preserving speedometer accuracy and ride comfort. Always consult manufacturer specifications or trusted references to select compatible tires and rims for your Audi A6 Avant (4G5, C7, 4GD).\n\nProper tire and rim selection ensures optimal safety, performance, and tire longevity.
