Wheels delivered in 4 to 8 working weeks, shipping included, from full payment for an order on the website, or from the deposit for an order on quotation, and at the earliest from your approval of the measurements, the colour or the 3D render you asked for, under article 5.1 of the Terms and Conditions.
The offset and width of your wheels do not come from a table: the Onyx Forged design office calculates them for your car and your brakes, and submits them to you before machining.
Frequently asked questions: wheels for the BMW 3 Series G20
What are the original offsets for the wheels of a BMW 3 Series G20?
The shop of the BMW dealer FABA lists, for the 3 Series Saloon G20, wheels from its catalogue that differ from one axle to the other. In 20 inches: 8J with an offset of 27 at the front and 8.5J with an offset of 40 at the rear. In 19 inches: the same widths and the same offsets. In 18 inches: 7.5J with an offset of 25 at the front and 8.5J with an offset of 40 at the rear. In 17 inches: 7.5J with an offset of 30 on both axles. The shop states that the car's model series is not enough and asks for the chassis number to be checked. [6, 8, 9, 10, 11, 12, 13, 14]
Which tyres come with the 20-inch complete wheels for a 3 Series G20?
225/35 R20 at the front and 255/30 R20 at the rear: these are the tyres that the shop of the BMW dealer FABA sells with the M Performance Y-Speiche 795 complete wheels, black or bicolour, which it lists as compatible with the 3er Limousine G20. [6, 7]
What PCD, centre bore and bolts does a BMW 3 Series G20 use?
The PCD is 5x112, the centre bore 66.6 mm and the wheel bolts are M14 x 1.25: SCC, wheelfitment.eu, koleso.ee and wheel-sizes.com give these measurements. hubcentric-rings.com gives a different centre bore for the G20 and G21 line; we follow the other four, which agree, pending a BMW document. The tightening torque is not published: the databases do not agree. [1, 2, 3, 4, 5]
Do the 3 Series G20 wheels also fit the Touring G21?
The catalogue of the BMW dealer FABA lists the 17, 18 and 19-inch wheels on this page for the 3er Limousine G20 and for the 3er Touring G21; wheelfitment.eu gives a single record, with the same hub measurements, for the G20 and the G21. The 20-inch complete wheels are listed for the Limousine G20 and the 4 Series Coupé G22. [3, 6, 8, 10, 12, 14]

Publication rule: a measurement is shown only if a primary source gives it (a manufacturer's document, an official vehicle type record, an original parts catalogue, the maker of the original wheel) without another primary source contradicting it, or if two independent specialist sources agree without a primary source contradicting them. The press and forums do not count. Measurements checked on 15 October 2026 by the Onyx Forged design office.

Custom forged wheels for the BMW 3 Series G20
- Forged 6061-T6 aluminium
- 5-axis CNC machining
- Designed to JWL/VIA standards
- Fitment worked out for your BMW 3 Series G20
3 Series G20: 5x112 on a 66.6 mm hub
The BMW 3 Series, type G20, produced since 2019, is 5x112, on a 66.6 mm hub, with M14 x 1.25 wheel bolts: SCC, wheelfitment.eu, koleso.ee and wheel-sizes.com, four independent specialist sources, give these measurements, each cited in the table. hubcentric-rings.com gives a different centre bore for the G20 and G21 line; we follow the other four, which agree, as no BMW document settles the question. The tightening torque is not published: the databases do not agree, and no BMW document we have read settles it; keep to the one in your car's manual. The bolt seat is given by only one source: it is not published here.
The BMW catalogue wheels, from 17 to 20 inches
The shop of the BMW dealer FABA, which sells genuine BMW parts and accessories, lists wheels for the 3 Series G20, showing the part number and the compatible car for each, with widths and offsets that differ from one axle to the other. In 20 inches, the M Performance Y-Speiche 795 forged complete wheels, black or bicolour: 8J with an offset of 27 and 225/35 R20 tyres at the front, 8.5J with an offset of 40 and 255/30 R20 tyres at the rear. In 19 inches, the M Doppelspeiche 791 M: 8J with an offset of 27 at the front, 8.5J with an offset of 40 at the rear. In 18 inches, the M Doppelspeiche 790 and the Doppelspeiche 796 M: 7.5J with an offset of 25 at the front, 8.5J with an offset of 40 at the rear. In 17 inches, the V-Speiche 775: 7.5J with an offset of 30 on both axles. The shop states that the car's model series is not enough to guarantee that a wheel fits, and asks for the chassis number to be checked.
Genuine accessories, not standard fitments
These wheels are genuine accessories: the catalogue gives their part number and the compatible car, but does not say which of them are fitted when new, or for which engine, and this page does not claim to. Only the 20-inch complete wheels give the tyre for each axle; the 17 to 19-inch wheels are sold without tyres and the cell stays empty. The 17 to 19-inch wheels are also listed for the Touring G21.
What we record before machining
- The exact version, petrol, diesel or M Performance, stated on the registration document.
- The braking system, on which the smallest possible diameter depends.
- The current fitment, axle by axle, and the 66.6 mm hub centre bore, on which the sources differ and which we check.
