Alfa Romeo Giulietta Sprint wheel specs by year and trim
| Year | Model / trim | Bolt pattern | Center bore | OE wheel |
|---|---|---|---|---|
| 2015 | Alfa Romeo Giulietta Sprint | 5x110 | 65.1 mm | 17x7.5J |
| 1961 | Alfa Romeo Giulietta Sprint | 4x98 | 58.6 mm | 15x4.5J |
Factory wheel sizes on the Alfa Romeo Giulietta Sprint
Across the 2 Alfa Romeo Giulietta Sprint trims with a documented factory wheel, the OE diameter is 15-17 inch, width 4.5-7.5J. 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 Alfa Romeo Giulietta Sprint (5x110, 65.1 mm Bore)
In our database, 108 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 2.2% of the vehicle pages in our English fitment guide (145 of 6,503); 96.6% of those also use a 65.1 mm center bore.
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 Alfa Romeo Giulietta Sprint?
The Alfa Romeo Giulietta Sprint uses a 5x110 bolt pattern on most variants we cover with a 65.1mm center bore. Other generations use 4x98 / 58.6mm (1961–1961). Always check the exact year and trim before ordering.
What is the Alfa Romeo Giulietta Sprint center bore?
The hub-centric center bore is 65.1 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 Alfa Romeo Giulietta Sprint 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 Alfa Romeo Giulietta Sprint?
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.
