Alfa Romeo Alfetta GTV wheel specs by year and trim
| Year | Model / trim | Bolt pattern | Center bore | OE wheel |
|---|---|---|---|---|
| 1980 | Alfa Romeo Alfetta GTV 6 2.5i | 4x98 | 58.6 mm | 14x6.0J |

Factory wheel sizes on the Alfa Romeo Alfetta GTV
Across the 2 Alfa Romeo Alfetta GTV trims with a documented factory wheel, the OE diameter is 14 inch, width 5.5-6J. A forged wheel that keeps the 4x98 bolt pattern and the 58.6 mm hub bore 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.

Hub-Centric Rings for a 58.6 mm Center Bore
A wheel with a center bore larger than 58.6 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 60.1 mm | 60.1 → 58.6 mm |
| 63.4 mm | 63.4 → 58.6 mm |
| 64.1 mm | 64.1 → 58.6 mm |
| 65.1 mm | 65.1 → 58.6 mm |
| 73.1 mm | 73.1 → 58.6 mm |
ANKUSI forged wheels are bored to exactly 58.6 mm for this vehicle, so no ring is needed.

FAQ
What is the bolt pattern on a Alfa Romeo Alfetta GTV?
The Alfa Romeo Alfetta GTV uses a 4x98 bolt pattern with a 58.6mm center bore across every Alfetta GTV variant in our database (2 guides, 1976–1980).
What is the Alfa Romeo Alfetta GTV center bore?
