BMW M240i Wheel Lug Pattern, Offset, Center Bore & Rim Size Reference
The BMW M240i features specific wheel lug patterns vital for selecting the correct aftermarket or replacement wheels. Understanding the lug count and PCD (pitch circle diameter) is essential for proper wheel mounting and vehicle safety. Typically, the M240i uses a 5×120 mm lug pattern, which is standard across many BMW models.\n\nOffset (ET) values and center bore dimensions also play critical roles in wheel compatibility. The M240i typically has an offset ranging between ET30 and ET40 depending on the production year and wheel size. The center bore is approximately 72.6 mm, matching the hub diameter to ensure a secure fit.\n\nRim sizes for the M240i vary by year and trim but generally range from 17 to 19 inches in diameter with widths between 7 to 8.5 inches. These specifications affect tire fitment and vehicle handling characteristics. Reviewing year-sorted reference tables for proper lug pattern, offset, center bore, and rim size ensures optimized wheel fitment.
