Diameter matches only: confirm approved sizes, wheel width, clearance, load and speed ratings before fitting. Vehicle-specific limits may be stricter.
BMW 3 Series wheel fitment and alloy wheel options
Compare the wheel and tyre proportions above, then check the mounting details for your BMW 3 Series 2012. Match the application to your engine and trim; wheel diameter alone does not determine whether an alloy wheel fits. The saved applications below remain tied to this vehicle selection when you change the preview tyre sizes.
PCD and centre bore
Recorded bolt pattern: 5x120. Recorded centre bore (mm): 72.6.
Wheel offset (ET)
Recorded offset (ET mm) varies across the saved applications. Check the matching tyre, engine and variant in the recorded wheel details below. Offset describes the mounting face position relative to the wheel centreline. Read front and rear values separately; individual listed offsets do not define a universal minimum-to-maximum range.
Rim width and diameter
Recorded wheel width / diameter varies across the saved applications. Check the matching tyre, engine and variant in the recorded wheel details below. A larger diameter can provide a different visual balance, but wheel width and offset also determine inner and outer clearance. The drawings compare nominal tyre dimensions; they do not simulate spoke or brake clearance.
Wheel fixings and fitting checks
Recorded wheel fixings: Bolt M14 x 1.25. Use the specified fixing seat and tightening torque for the actual application. Check wheel load capacity, brake and hub clearance, and TPMS or valve requirements before fitting.

Keep tyre-width changes modest and check clearance at full steering lock and through suspension travel. Select a suitable wheel width and offset for a spacer-free fit; spacers are not an automatic solution to rubbing. PCD and centre bore matches alone do not confirm that an aftermarket wheel fits.
Results compare nominal sizes. They do not confirm vehicle or wheel fitment.
