Amounts in pounds: our checkout on 4 October 2026, before the carrier's clearance fee and any import duty. The amount shown at checkout is the one charged for your order.

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 Cupra Formentor KM

What are the original offsets for the wheels of a Cupra Formentor?

An offset of 40 on every wheel, on both axles, according to the Swiss vehicle type records: 8.5J x 20 on the VZ5, 8J x 19 on the 228 and 180 kW 2.0 TSI and on the e-Hybrid, 8J x 18 and 8J x 19 on the 140 kW 2.0 TSI and the 110 kW 1.5 TSI. [7, 8, 9, 10, 11, 12, 13, 14, 15, 16]

Which tyres, and which load index, does a Cupra Formentor take?

255/35 R20 with load index 97, i.e. 730 kg per tyre, on the VZ5; 245/40 R19 with load index 94 or 98, i.e. 670 or 750 kg, on the 19-inch wheels; 245/45 R18 with load index 96, i.e. 710 kg, on the 18-inch wheels. These are the combinations in the Swiss vehicle type records. [7, 10, 15, 17]

What is the load per wheel on a Cupra Formentor VZ5?

The Swiss vehicle type record of the VZ5 gives it a permissible load of 1,110 kg on the front axle, i.e. 555 kg per front wheel. The 255/35 R20 tyre with load index 97 in the same record carries 730 kg. [7, 17]

What PCD, centre bore and bolts does a Cupra Formentor use?

The PCD is 5x112, the centre bore 57.1 mm, and the wheels are held by M14 x 1.5 bolts: SCC, wheelfitment.eu, hubcentric-rings.com and koleso.ee give these measurements. The CUPRA owner's manual sets the tightening torque of the bolts at 140 Nm. [1, 2, 3, 4, 5, 6]

Same fixing measurements

As original equipment, these cars have the same PCD, centre bore, thread and fixing as the Cupra Formentor KM: PCD 5x112, centre bore 57.1 mm, thread M14 x 1.5, fixing: wheel bolts.

Same fixing measurements; original diameters and offsets: see each car's page. The seat of the bolts or nuts, the width of the wheels and brake clearance are not compared here: this comparison is not an opinion on compatibility.

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 20 October 2026 by the Onyx Forged design office.

Custom forged wheels for the Cupra Formentor KM

  • Forged 6061-T6 aluminium
  • 5-axis CNC machining
  • Designed to JWL/VIA standards
  • Fitment worked out for your Cupra Formentor KM

Formentor KM: 5x112, a 57.1 mm hub, M14 x 1.5 bolts

The Cupra Formentor (type KM), produced since 2020, uses 5x112 on a 57.1 mm hub, with M14 x 1.5 wheel bolts: SCC, wheelfitment.eu, hubcentric-rings.com and koleso.ee give these measurements. The CUPRA owner's manual sets the tightening torque of the bolts at 140 Nm. The bolt seat is given by only one source: it is not published here.

An offset of 40 on every wheel

The Swiss vehicle type records for the Formentor, from 2020 to 2023, give an offset of 40 for all its wheels, on both axles. The VZ5, a 287 kW 2.5 TFSI, runs on 8.5J x 20 with 255/35 R20 tyres. The 2.0 TSI, in its 228 kW all-wheel-drive and 180 kW front-wheel-drive versions, is permitted on 8J x 19 with 245/40 R19 tyres, as is the e-Hybrid; the 140 kW 2.0 TSI and the 110 kW 1.5 TSI are also permitted on 8J x 18 with 245/45 R18 tyres. In winter, the VZ5 moves to 8J x 19, and the other versions to 8J x 18 or 7.5J x 17.

What these measurements say about a forged wheel

The offset positions the wheel in the wheel arch: a wider wheel, or a lower offset, brings it closer to the wing. The Onyx Forged design office starts from the measurements on this page, your brakes and your tyres to calculate the width and offset of your wheels, then submits them to you. The offset calculator compares two fitments: it compares, it does not choose the measurement for you.

And the facelifted Formentor?

The records we have read stop at 2023. For a facelifted Formentor, VZ5 included, the Onyx Forged design office establishes the fitment from its registration document or its VIN; koleso.ee gives it the same hub. The Cupra Leon shares the PCD (bolt pattern), centre bore and bolts of the Formentor, not its offsets.

What we record before machining

Configure your forged wheels for the Cupra Formentor (KM)

The Onyx Forged design office works out the measurements of your car from its exact version, stated on the registration document, and shows them to you before machining. Each set is cut from forged 6061-T6 aluminium, machined on a 5-axis CNC centre, as monoblock, two-piece or three-piece wheels; our wheels are designed to JWL/VIA standards. Prices by diameter and the lead time are given on this page, under “What Onyx can make”. Start your configuration or write to contact@onyxforgedwheels.com.
