These are vehicle-year records whose recorded OEM ranges overlap this 2015 BMW M4. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 95 donor years. Listed 24 eligible overlaps (not all evaluated years are compatible). Showing all listed.
Years grouped because recorded compatibility evidence is equivalent. Each year keeps its own page.
Approximate position vs the mid OEM package: outer change -2.18 mm, inner change -4.18 mm. This uses aggregated width/offset ranges, not a specific wheel.

Recorded vehicle-side thread for the 2015 BMW M4 is M14x1.25. This donor year is recorded as M12x1.5. That is the vehicle stud/nut thread, not an intrinsic thread stamped on the wheel. Hardware must match this vehicle’s studs and the selected wheel’s seat and engagement. Existing hardware may be reusable if it already matches. Seat style is not in this dataset, so products are not a verified fit.

Recorded vehicle-side thread differs (M12x1.5 on the donor year vs M14x1.25 on the target vehicle). Hardware must match the target vehicle’s studs and the selected wheel’s seat. Existing hardware may be reusable if it already matches. Seat style is not confirmed in this dataset. Approximate position vs the mid OEM package: outer change -4.18 mm, inner change -2.18 mm.

Dataset suggestionWheel spacer ≈ 7.18 mm – not a verified installation requirement.
A spacer of about 7.18 mm is a dataset suggestion only; clearance is not verified. Estimated outer position is about 7.18 mm farther inward than the mid OEM package. Recorded vehicle-side thread differs (M14x1.5 on the donor year vs M14x1.25 on the target vehicle). Hardware must match the target vehicle’s studs and the selected wheel’s seat. Existing hardware may be reusable if it already matches. Seat style is not confirmed in this dataset.
Only years with evidence-based interchange relationships are listed. Adjacent years are not assumed compatible.

The values below reflect the OEM specifications provided for this page. BMW offered multiple factory wheel-tire packages and front-rear variations on the M4, so some dimensions can vary by trim, axle, or option package. If a spec on your vehicle differs, use the on-page calculator and confirm against the door-jamb label, owner’s manual, or an official BMW parts catalog for your VIN.
| Bolt pattern (studs x PCD) | 5x120 |
| Center bore | 72.6 mm |
| Thread size | M14 x 1.25 |
| Rim diameter | 19 in |
| Rim width | 9.0 in |
| Wheel offset (ET) | 29 mm |
| Backspacing | 5.64 in |
| Tire section width | 255 mm |
| Tire aspect ratio | 40 |
| Tire rim diameter | 18 in |
Notes:
The calculator lets you compare a donor wheel-tire setup to your 2015 BMW M4 and also test custom sizes. Follow these steps:
Plus sizing involves increasing wheel diameter and often width, then selecting a tire with a lower aspect ratio to keep overall diameter close to stock. This can sharpen steering response and alter ride quality and impact resistance. For the 2015 BMW M4:
Because packages and axle specs vary, do not assume a specific plus-size will fit all 2015 M4 trims. Confirm with the calculator and OEM references for your VIN.
What is the bolt pattern for the 2015 BMW M4?
5x120.
What center bore does the 2015 M4 require?
72.6 mm. If your aftermarket wheel has a larger bore, use hub-centric rings sized to 72.6 mm at the hub side.
Does the M4 use wheel bolts or lug nuts, and what thread size?
It uses wheel bolts. The thread is M14 x 1.25 according to the provided OEM data.
What is the stock wheel offset?
The provided OEM offset is ET 29 mm. This may vary by axle or package. Verify your specific wheels by checking the stamp on the wheel, your door-jamb label, and OEM sources by VIN.
Can I run 20 inch wheels on my 2015 M4?
Fitment depends on wheel width, offset, and tire size. Use the calculator to compare inner and outer clearances and overall tire diameter to your baseline, then confirm against OEM guidance. Do not purchase until you verify clearance at full lock and full suspension compression.
What tire size came stock?
The values provided include a 255/40R18 tire. BMW offered multiple packages on the M4, and sizes can vary by axle and trim. Confirm your specific sizes on your door-jamb label and owner’s manual, then use those as your calculator baseline.
Do I need hub-centric rings?
If your wheel’s center bore is larger than 72.6 mm, use rings so the wheel centers on the hub. If the wheel bore is 72.6 mm already, rings are not needed.
What torque should I use on the wheel bolts?
Torque values can vary by wheel type and OEM guidance. Check your owner’s manual or an OEM service source for your VIN. Do not guess. Re-torque after 50 to 100 miles.
Can I use spacers on the M4?
Only if you also use proper hub-centric spacers and longer M14 x 1.25 bolts that maintain correct thread engagement and seat profile. Use the calculator to ensure the final effective offset still clears suspension and fenders.
Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:
A normal wheel spacer does not change bolt pattern. Hub rings cannot enlarge a wheel bore that is smaller than the hub. Brake clearance and tire package fitment still require vehicle-specific checks when not confirmed in the dataset.
