Porsche 924 wheel specs by year and trim
| Year | Model / trim | Bolt pattern | Center bore | OE wheel |
|---|---|---|---|---|
| 1980 | Porsche 924 Turbo | 5x130 | 71.6 mm | 15x6J |

Factory wheel sizes on the Porsche 924
Across the 2 Porsche 924 trims with a documented factory wheel, the OE diameter is 14-15 inch, width 5.5-6J. A forged wheel that keeps the bolt pattern and hub bore of your generation (see the table above) and matches the factory offset listed on the model page bolts on without spacers or hub rings. Going one inch up in diameter with a lower-profile tyre keeps the rolling circumference inside the usual 1.5% tolerance; every extra 0.5J of width moves the outer lip about 6 mm outward at the same offset, and each 5 mm less offset moves the whole wheel 5 mm outward.

Vehicles With the Same Hub as the Porsche 924 (5x130, 71.6 mm Bore)
In our database, 84 other vehicle entries from 9 makes use exactly the same 5x130 bolt pattern and 71.6 mm center bore. Factory wheels from these cars bolt on and center on the hub without rings; offset and width still have to be checked.
5x130 is used by 5.8% of the vehicle entries in our database (375 of 6,503); 78.7% of those also use a 71.6 mm center bore.
Hub-Centric Rings for a 71.6 mm Center Bore
A wheel with a center bore larger than 71.6 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 72.6 mm | 72.6 → 71.6 mm |
| 73.1 mm | 73.1 → 71.6 mm |
| 74.1 mm | 74.1 → 71.6 mm |
| 76.1 mm | 76.1 → 71.6 mm |
ANKUSI forged wheels are bored to exactly 71.6 mm for this vehicle, so no ring is needed.

FAQ
What is the bolt pattern on a Porsche 924?
The Porsche 924 uses a 5x130 bolt pattern on most variants we cover with a 71.6mm center bore. Other generations use 4x108 / 57.1mm (1977–1977). Always check the exact year and trim before ordering.
What is the Porsche 924 center bore?
The hub-centric center bore is 71.6 mm on the most common generation; see the table for variants. Aftermarket wheels should match this bore or use hub-centric rings so the hub, not the bolts, carries the load.
Do all Porsche 924 years share the same wheel fitment?
No. The bolt pattern or center bore changed between generations, so wheels are not interchangeable across all years. Use the year-by-year table on this page to pick the right specification.
Which forged wheels fit the Porsche 924?
Any wheel drilled 5x130 with a 71.6mm hub bore in the offset range shown on the model guide. ANKUSI forges wheels to order for this exact specification, in 14–24 inch diameters, so no adapters or hub rings are needed.
