How to Read Wheel Offset & Measurements
Use these two references before ordering: the left diagram shows where each spec (PCD, center bore, offset, width and diameter) is measured on the wheel; the right diagram shows how positive, zero and negative offset shift the wheel face relative to the hub centerline.
ANKUSI Engineering Expert Advice
A sedan's wheel spec is a balance point the factory tuned between ride comfort, steering feel, and everyday durability. Forging lets us hold that same structural margin while cutting rotational mass, which is where most of the real-world benefit — quicker steering response, marginally better ride — actually comes from.
The BMW M5 Alpin White G90 runs a 5x132 bolt pattern, 66.6mm center bore, and a F: 20x9.5J wheel from the factory. Our Flush Fitment reference is F 21x10.0J ET15 / R 22x11.0J ET15, which tucks the tire under the fender lip on a stock-height BMW M5 Alpin White G90. Our Maximum Aggressive reference is F 21x10.5J ET12 / R 22x11.5J ET12 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
BMW M5 Alpin White OE Wheel Specs
The 2025 BMW M5 Alpin White G90 (Sedan) uses a 5x132 bolt pattern with a 66.6mm center bore. Factory wheels are F: 20x9.5J R: 21x10.5J.
Why the factory spec works for most owners:
- Balances ride comfort with everyday fuel efficiency
- A widely used size in this segment, so tire and wheel availability stays strong
- Keeps unsprung weight low for stable, predictable handling
- Maintains clearance for the factory brake calipers and suspension components
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the BMW M5 Alpin White G90 (2025) we drill the 5x132 pattern and cut the centre bore to 66.6mm on our own CNC line, so the wheel hub-centres on the car with no spacer rings, in whatever diameter, width and offset you specify.

Flush Fitment
For a flush look with minimal rubbing, F 21x10.0J ET15 / R 22x11.0J ET15 is the recommended starting point on a stock or mildly lowered BMW M5 Alpin White G90.
Maximum Aggressive Fitment
F 21x10.5J ET12 / R 22x11.5J ET12 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Decision Guide
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: F 20x9.5J ET28 → ~6.35″ F backspacing, R 21x10.5J ET28 → ~6.85″ R backspacing
- Flush: F 21x10.0J ET15 → ~6.09″ F backspacing, R 22x11.0J ET15 → ~6.59″ R backspacing
- Max: F 21x10.5J ET12 → ~6.22″ F backspacing, R 22x11.5J ET12 → ~6.72″ R backspacing
Want to check a different width or offset before you order? Use our Offset & Backspacing Calculator to solve the numbers yourself, or looking for your exact BMW spec, or want a wheel built to a custom offset for your BMW M5 Alpin White G90? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Custom Forged Wheels for the BMW M5 Alpin White G90 (2025)
Everything above is reference data. If you want wheels actually built to it, that is what ANKUSI does: we are a forged wheel factory in Guangzhou, China, IATF 16949 and ISO 9001 certified, forging on our own 10,000-ton press and producing over 120,000 wheels a year. Forging blank, CNC machining, finishing, coating and inspection all happen in the same building — nothing is subcontracted and nothing is relabelled from another manufacturer.
Every set is cut to order, so the 5x132 pattern and the 66.6mm centre bore are machined for this car specifically rather than shimmed with adaptor rings. Diameter, width, offset, concavity, monoblock or multi-piece construction and the finish are all yours to choose.
We do not hold 5x132 wheels on a shelf — they are forged to order, which is why any offset, width and bore combination on this page is buildable rather than limited to a stock list.

Wheel Installation Reference: Torque, Thread & TPMS
Thread & Fastener: M14x1.25, 60-degree conical-seat lug bolt.
Factory Torque Spec: 140 Nm (103 ft-lb). Consistent across modern BMW passenger and X-series models using factory conical-seat bolts.
TPMS: TPMS (Tire Pressure Monitoring System) has been federally mandated on all new light vehicles sold in the US since the 2008 model year. If your wheels use OE-style sensors, have them transferred or cloned to the new wheels at installation.
Tire Pressure: Always set tire pressure to the value on your vehicle's tire placard (driver's doorjamb or glovebox), not the max PSI printed on the tire sidewall — this is trim- and tire-size-specific and stays the same reference point when you switch to a different wheel and tire combination.
Reference data compiled from published OEM service specifications and cross-checked against independent repair sources; always confirm against your owner's manual or door-jamb placard before installation.
