OX-B12 Sonora — monoblock forged wheels for BMW, Audi, Porsche…

In short: OX-B12 Sonora: monoblock forged wheels, 18″ to 24″, priced per set of four wheels from €3,200.

The OX-B12 Sonora is a monoblock off-road forged wheel with six double spokes. Twelve arms leave the hub in pairs and rest on an outer ring dotted with rivet heads: the look of an expedition wheel, machined from the solid. The riveted ring is decorative: the wheel remains a single piece, with no assembly. At the centre, the cap carries the OX monogram. In satin black, it gives the vehicle a raw look; in anthracite grey, it keeps a technical tone; in satin bronze, it takes on the colour of the desert.

Offered from 18″ to 24″. It is designed for pick-ups and 4×4s.

Engineering and specifications

Measurements: PCD (bolt pattern), offset (ET) and centre bore machined for your car, to the measurements the Onyx Forged design office submits to you before machining; no spacers or spigot rings to add.
Standards: wheels designed to JWL/VIA standards.

Fitted on my Corvette C8. Dimensions were checked and confirmed before production, the finish is very even and the set arrived within the quoted lead time, each wheel in its own sleeve.

Le rendu 3D sur ma Camaro m'a convaincue, et le résultat est fidèle au rendu. Bronze satiné régulier, montage sans bague ni cale. Très bon suivi par mail du devis à la livraison.

Questions about the OX-B12 Sonora

Will the OX-B12 Sonora fit my car?

It is machined to your car's measurements. Give your car's make, model and year when you order: the Onyx Forged design office works out the PCD (bolt pattern), the offset (ET) and the centre bore, and submits them to you before machining. No spacers or spigot rings are needed. Our guides: PCD, bolt pattern and centre bore and brake caliper clearance.

What tyre size goes with a bigger wheel?

Our tyre size calculator compares your original tyre with a size for the new rim diameter: overall diameter, sidewall height and speedometer error, against the ETRTO tolerance. Your vehicle handbook, the tyre placard and your insurer have the final say. Our guide: How to read a tyre size (and the load and speed index).

Does the finish change the price of the OX-B12 Sonora?

No. Every finish listed on this page costs the same for a given diameter, and another colour, from our palette or from a RAL or other reference, does not change the price shown either.
