|---|---|---|---|---|---|
| Factory (OE) | 18x8J | ET42 | 6.15 in (156 mm) | — | — |

Hub-Centric Rings for a 121.3 mm Center Bore
A wheel with a center bore larger than 121.3 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 130.1 mm | 130.1 → 121.3 mm |
ANKUSI forged wheels are bored to exactly 121.3 mm for this vehicle, so no ring is needed.
