In most modern BMW X1s, lug nuts use M12 x 1.5 threading with a 60-degree conical seat, tightened to about 120 Nm. The typical removal socket is 17 mm, though some wheels may require 19 mm. Always verify the exact spec for your vehicle in the owner's manual or the driver-side door placard.
The following article explains the common specifications for the X1’s lug hardware, notes potential variations across generations and wheel options, and provides practical steps to verify the correct lug nut size for your specific X1 when changing wheels or replacing fasteners.
