Cadillac XT5 wheel specs by year and trim

| 2017 | Cadillac XT5 | 6x120 | 66.9 mm | 18x8.0J |

Factory wheel sizes on the Cadillac XT5
Across the 3 Cadillac XT5 trims with a documented factory wheel, the OE diameter is 18 inch, width 8J and offset ET50. A forged wheel that keeps the 6x120 bolt pattern and the 66.9 mm hub bore 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 Cadillac XT5 (6x120, 66.9 mm Bore)
In our database, 25 other vehicle entries from 4 makes use exactly the same 6x120 bolt pattern and 66.9 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.
6x120 is used by 0.5% of the vehicle pages in our English fitment guide (34 of 6,503); 97.1% of those also use a 66.9 mm center bore.
Hub-Centric Rings for a 66.9 mm Center Bore
A wheel with a center bore larger than 66.9 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 67.1 mm | 67.1 → 66.9 mm |
| 70.1 mm | 70.1 → 66.9 mm |
| 70.5 mm | 70.5 → 66.9 mm |
| 71.6 mm | 71.6 → 66.9 mm |
| 73.1 mm | 73.1 → 66.9 mm |
ANKUSI forged wheels are bored to exactly 66.9 mm for this vehicle, so no ring is needed.

FAQ
What is the bolt pattern on a Cadillac XT5?
The Cadillac XT5 uses a 6x120 bolt pattern with a 66.9mm center bore across every XT5 variant in our database (3 guides, 2017–2020).
What is the Cadillac XT5 center bore?
The hub-centric center bore is 66.9 mm. Aftermarket wheels should match this bore or use hub-centric rings so the hub, not the bolts, carries the load.
Do all Cadillac XT5 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 Cadillac XT5?
Any wheel drilled 6x120 with a 66.9mm 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.
