Factory wheel sizes on the Saab 900
Across the 3 Saab 900 trims with a documented factory wheel, the OE diameter is 15 inch, width 5.5-6J and offset ET40-49. A forged wheel that keeps the bolt pattern and hub bore of your generation (see the table above) and stays inside that offset range 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 Saab 900 (5x110, 65.1 mm Bore)
In our database, 110 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) | 15x6J | ET49 | 5.43 in (138 mm) | — | — |
| Flush | 17x7.5J | ET40 | 5.82 in (148 mm) | +10 mm | +28 mm |
| Maximum | 18x8J | ET35 | 5.88 in (149 mm) | +11 mm | +39 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 Saab 900?
The Saab 900 uses a 5x110 bolt pattern on most variants we cover with a 65.1mm center bore. Other generations use 4x114.3 / 71.5mm (1984–1984). Always check the exact year and trim before ordering.
What is the Saab 900 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 Saab 900 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 Saab 900?
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.
