Factory wheel sizes on the Buick Encore GX
Across the 7 Buick Encore GX trims with a documented factory wheel, the OE diameter is 18 inch, width 7.5J. A forged wheel that keeps the 5x115 bolt pattern and the 70.3 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 Buick Encore GX (5x115, 70.3 mm Bore)
In our database, 88 other vehicle entries from 8 makes use exactly the same 5x115 bolt pattern and 70.3 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.
5x115 is used by 3.2% of the vehicle entries in our database (209 of 6,503); 65.1% of those also use a 70.3 mm center bore.
Hub-Centric Rings for a 70.3 mm Center Bore
A wheel with a center bore larger than 70.3 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 70.5 mm | 70.5 → 70.3 mm |
| 71.6 mm | 71.6 → 70.3 mm |
| 72.6 mm | 72.6 → 70.3 mm |
| 73.1 mm | 73.1 → 70.3 mm |
ANKUSI forged wheels are bored to exactly 70.3 mm for this vehicle, so no ring is needed.

FAQ
What is the bolt pattern on a Buick Encore GX?
The Buick Encore GX uses a 5x115 bolt pattern with a 70.3mm center bore across every Encore GX variant in our database (7 guides, 2020–2026).
What is the Buick Encore GX center bore?
The hub-centric center bore is 70.3 mm. Aftermarket wheels should match this bore or use hub-centric rings so the hub, not the bolts, carries the load.
Do all Buick Encore GX 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 Buick Encore GX?
Any wheel drilled 5x115 with a 70.3mm 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.
