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 Porsche Taycan Y1A
What is the wheel tightening torque on a Porsche Taycan?
160 Nm for the wheel bolts and 600 Nm for the nut on centre-lock wheels, according to Porsche's bulletin on permitted wheels and tyres. [5]
What are the original fitments of a Porsche Taycan?
19 inches: 8J ET 50 at the front, 10J ET 47 at the rear. 20 inches: 9J ET 54 and 11J ET 60. 21 inches: 9.5J ET 60 and 11.5J ET 66. The front and rear wheels differ at every diameter. [5]
Is the 19-inch fitment possible on every Taycan?
No. Porsche's bulletin excludes the 19-inch fitment on the Taycan Turbo, Turbo S and GTS, and with PCCB ceramic or PSCB surface-coated brakes. [5]
Same fixing measurements
As original equipment, these cars have the same PCD, centre bore, thread and fixing as the Porsche Taycan Y1A: PCD 5x130, centre bore 71.6 mm, thread M14 x 1.5, fixing: wheel bolts; centre-lock nut on centre-lock versions.
- Porsche 911 991 (2011–2019)
- Porsche 911 992 (since 2019)
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 15 October 2026 by the Onyx Forged design office.

Custom forged wheels for the Porsche Taycan Y1A
- Forged 6061-T6 aluminium
- 5-axis CNC machining
- Designed to JWL/VIA standards
- Fitment worked out for your Porsche Taycan Y1A
Taycan Y1A: 5x130, 71.6 mm, wheel bolts or centre-lock nut
The Taycan, type Y1A, is 5x130, on a 71.6 mm hub, with M14 x 1.5 wheel bolts: four independent specialist sources give the PCD (bolt pattern) and the centre bore, three the thread, each cited in the table. Porsche's bulletin on permitted wheels and tyres, for its part, gives two fixing types: wheel bolts, tightened to 160 Nm, and the centre-lock nut, tightened to 600 Nm. The two are not interchangeable, and the wheel must be machined for the one on your car.
Three diameters, a rear that is always wider
According to Porsche's bulletin (model years 2020 to 2024), the Taycan takes 19-inch wheels in 8J ET 50 at the front and 10J ET 47 at the rear, 20-inch wheels in 9J ET 54 and 11J ET 60, and 21-inch wheels in 9.5J ET 60 and 11.5J ET 66. At each diameter, the rear is wider and its offset differs: a front wheel and a rear wheel are never swapped.
Which diameter for which version
The 19-inch fitment is excluded on the Taycan Turbo, Turbo S and GTS, and with PCCB ceramic or PSCB surface-coated brakes. The 20-inch fitment is excluded on the Turbo S, except on the Turbo S Cross Turismo, which then takes 255/40 ZR20 at the front and 295/35 ZR20 at the rear, on the same widths and the same offsets. The bulletin does not exclude the 21-inch fitment on any version. We start from the exact version of your car, stated on the registration document, never from the model name alone.
Configure your forged wheels for the Taycan Y1A
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.
