Audi A4 Cabrio (8H7, B6, 8HE, B7) Wheel Lug Patterns, Offset ET & Center Bore Reference

The Audi A4 Cabrio (8H7, B6, 8HE, B7) series features precise wheel lug patterns designed for optimal fitment and safety. Each model year shares key specification elements including a common lug count and PCD (Pitch Circle Diameter), supported by exact offset ET and center bore measurements to ensure proper wheel alignment and clearance.\n\nTypically, the Audi A4 Cabrio wheel lug pattern is 5×112 mm PCD, a standard fit for many Audi models. Wheels with matching offset ET values, generally ranging from ET32 to ET45 depending on model year and trim, provide balanced wheel positioning. The center bore diameter consistently measures 57.1 mm, facilitating perfect hub centering and reducing vibration.\n\nWheel rim sizes for the A4 Cabrio vary by production year and variant, commonly spanning from 16 to 18 inches in diameter. Using the correct lug pattern and rim dimensions based on this year-sorted reference guarantees compatibility and preserves driving dynamics.
