Alfa Romeo 156 Crosswagon wheel specs by year and trim
| Year | Model / trim | Bolt pattern | Center bore | OE wheel |
|---|---|---|---|---|
| 2004 | Alfa Romeo 156 Crosswagon | 5x98 | 58.1 mm | 17x7.0J |

Factory wheel sizes on the Alfa Romeo 156 Crosswagon
Across the 2 Alfa Romeo 156 Crosswagon trims with a documented factory wheel, the OE diameter is 17 inch, width 7J. A forged wheel that keeps the 5x98 bolt pattern and the 58.1 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.
Vehicles With the Same Hub as the Alfa Romeo 156 Crosswagon (5x98, 58.1 mm Bore)
In our database, 10 other vehicle entries from 5 makes use exactly the same 5x98 bolt pattern and 58.1 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.
5x98 is used by 0.5% of the vehicle pages in our English fitment guide (32 of 6,503); 96.9% of those also use a 58.1 mm center bore.
Hub-Centric Rings for a 58.1 mm Center Bore
A wheel with a center bore larger than 58.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 60.1 mm | 60.1 → 58.1 mm |
| 63.4 mm | 63.4 → 58.1 mm |
| 64.1 mm | 64.1 → 58.1 mm |
| 65.1 mm | 65.1 → 58.1 mm |
| 73.1 mm | 73.1 → 58.1 mm |
ANKUSI forged wheels are bored to exactly 58.1 mm for this vehicle, so no ring is needed.

FAQ
What is the bolt pattern on a Alfa Romeo 156 Crosswagon?
The Alfa Romeo 156 Crosswagon uses a 5x98 bolt pattern with a 58.1mm center bore across every 156 Crosswagon variant in our database (2 guides, 2004).
What is the Alfa Romeo 156 Crosswagon center bore?
The hub-centric center bore is 58.1 mm. Aftermarket wheels should match this bore or use hub-centric rings so the hub, not the bolts, carries the load.
Do all Alfa Romeo 156 Crosswagon 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 Alfa Romeo 156 Crosswagon?
Any wheel drilled 5x98 with a 58.1mm 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.
