Factory wheel sizes on the Buick Excelle
Across the 33 Buick Excelle trims with a documented factory wheel, the OE diameter is 14-16 inch, width 5.5-6.5J. 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 Buick Excelle (4x114.3, 56.6 mm Bore)
In our database, 5 other vehicle entries from 2 makes use exactly the same 4x114.3 bolt pattern and 56.6 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.
4x114.3 is used by 0.6% of the vehicle entries in our database (41 of 6,503); 17.1% of those also use a 56.6 mm center bore.
Hub-Centric Rings for a 56.6 mm Center Bore
A wheel with a center bore larger than 56.6 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 57.1 mm | 57.1 → 56.6 mm |
| 60.1 mm | 60.1 → 56.6 mm |
| 63.4 mm | 63.4 → 56.6 mm |
| 64.1 mm | 64.1 → 56.6 mm |
| 73.1 mm | 73.1 → 56.6 mm |
ANKUSI forged wheels are bored to exactly 56.6 mm for this vehicle, so no ring is needed.
Sources and Last Update
Bolt pattern and center bore were checked against at least two independent fitment references before publication.

FAQ
What is the bolt pattern on a Buick Excelle?
The Buick Excelle uses a 4x114.3 bolt pattern on most variants we cover with a 56.6mm center bore. Other generations use 5x105 / 56.6mm (2016–2023), 4x100 / 56.6mm (2018–2023), 5x115 / 70.3mm (2010–2015). Always check the exact year and trim before ordering.
What is the Buick Excelle center bore?
The hub-centric center bore is 56.6 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 Buick Excelle 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 Buick Excelle?
Any wheel drilled 4x114.3 with a 56.6mm 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.
