OX-S12 Kerala — monoblock forged wheels for Tesla, BMW, Audi…

In short: OX-S12 Kerala: monoblock forged wheels, 18″ to 24″, priced per set of four wheels from €3,200.

The OX-S12 Kerala is a monoblock forged wheel with twelve slim spokes. The spokes leave a dished hub, where the wheel nuts sit at the bottom, then run straight to the rim, barely tapering: twelve narrow, regular openings and a very concave face. Next to our OX-S10 Shibuya, the difference shows in two places: the Kerala has two more spokes, so tighter openings and a fuller face, and its spokes dive towards a deep hub instead of leaving a star-shaped hub flush with the face. The centre cap, in the colour of the wheel, carries the OX monogram. In satin black, the wheel looks like a racing wheel; in satin bronze, it warms up; in anthracite grey, it stays understated; in brushed silver, every spoke stands out.

Offered from 18″ to 24″. It is designed for light electric saloons and SUVs, where every kilo counts.

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.

Questions about the OX-S12 Kerala

Will the OX-S12 Kerala 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-S12 Kerala?

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.
