Acura RDX Wheel Lug Pattern and Fitment Guide
The Acura RDX uses specific wheel lug patterns that are critical for proper wheel fitment and safety. This guide details the lug count and pitch circle diameter (PCD) for each model year, along with essential specifications such as offset (ET) and center bore dimensions.\n\nTypically, the Acura RDX features a 5-lug pattern with a PCD of 120mm, but slight variations in offset and center bore exist across different years. Knowing the exact bolt pattern and rim size is crucial when selecting aftermarket wheels or replacements.\n\nOffset values (ET) for the Acura RDX generally range between 40mm to 50mm, balancing wheel alignment within the wheel well. Center bore diameter is standardized to ensure the wheel fits securely onto the hub, minimizing vibrations.\n\nBy referencing our year-sorted table of Acura RDX wheel specifications, owners can verify compatible rim sizes, bolt patterns, and offset measurements to optimize both performance and appearance.
