Holden Astra wheel specs by year and trim

Factory wheel sizes on the Holden Astra
Across the 3 Holden Astra trims with a documented factory wheel, the OE diameter is 16 inch, width 6.5J and offset ET37-49. A forged wheel that keeps the 5x110 bolt pattern and the 65.1 mm hub bore and stays inside that offset range bolts on without spacers or hub rings. The offset spread between trims is 12 mm, so read the year-by-year row for your exact car before choosing a width. 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 Holden Astra (5x110, 65.1 mm Bore)
In our database, 129 other vehicle entries from 18 makes use exactly the same 5x110 bolt pattern and 65.1 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.
5x110 is used by 2.1% of the vehicle entries in our database (136 of 6,396); 100.0% of those also use a 65.1 mm center bore.
Offset and Backspacing: Factory Wheel vs Options
Backspacing ≈ width/2 + ET/25.4 + 0.5 in. "Inward" means closer to the suspension; "outward" means closer to the fender lip.
| Setup | Size | ET | Backspacing | Inward vs OE | Outward vs OE |
|---|---|---|---|---|---|
| Factory (OE) | 16x6.5J | ET37 | 5.21 in (132 mm) | — | — |
| Flush | 17x7.5J | ET32 | 5.51 in (140 mm) | +8 mm | +18 mm |
| Maximum | 18x8J | ET30 | 5.68 in (144 mm) | +12 mm | +26 mm |
Hub-Centric Rings for a 65.1 mm Center Bore
A wheel with a center bore larger than 65.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 66.1 mm | 66.1 → 65.1 mm |
| 66.6 mm | 66.6 → 65.1 mm |
| 67.1 mm | 67.1 → 65.1 mm |
| 70.1 mm | 70.1 → 65.1 mm |
| 73.1 mm | 73.1 → 65.1 mm |
ANKUSI forged wheels are bored to exactly 65.1 mm for this vehicle, so no ring is needed.

FAQ
What is the bolt pattern on a Holden Astra?
The Holden Astra uses a 5x110 bolt pattern with a 65.1mm center bore across every Astra variant in our database (3 guides, 2003–2005).
What is the Holden Astra center bore?
The hub-centric center bore is 65.1 mm. Aftermarket wheels should match this bore or use hub-centric rings so the hub, not the bolts, carries the load.
Do all Holden Astra years share the same wheel fitment?
The bolt pattern and center bore are the same across the years we cover, but OE wheel width and offset differ by trim, so check the exact model line before choosing an aftermarket size.
Which forged wheels fit the Holden Astra?
Any wheel drilled 5x110 with a 65.1mm 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.
