Center bore is not the same across 8x165.1 vehicles: 121.3 mm (10 vehicles), 116.7 mm (10 vehicles). A wheel with the right bolt pattern but the wrong center bore will not seat on the hub — it needs to be machined to the exact bore or used with a hub-centric ring. Check the model page for your exact year before ordering.
Typical fastener: M14x1.5 Nut.
ANKUSI currently lists 29 forged wheel designs drilled 8x165.1, and every design can be machined to 8x165.1 with your vehicle's exact center bore and offset, in 14–24 inch diameters.

Bolt pattern alone does not guarantee a correct fit — center bore, offset, and load rating still need to be confirmed per vehicle. Check our Fitment Verification Checklist before ordering, or send us your VIN or trim level and we will confirm it for you.
Vehicles Using 8x165.1 With a 116.7 mm Center Bore
In our database, 19 other vehicle entries from 4 makes use exactly the same 8x165.1 bolt pattern and 116.7 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.
8x165.1 is used by 0.4% of the vehicle pages in our English fitment guide (29 of 6,503); 65.5% of those also use a 116.7 mm center bore.
Hub-Centric Rings for a 116.7 mm Center Bore
A wheel with a center bore larger than 116.7 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 130.1 mm | 130.1 → 116.7 mm |
ANKUSI forged wheels are bored to exactly 116.7 mm for this vehicle, so no ring is needed.
