Cadillac XT4 wheel specs by year and trim
| Year | Model / trim | Bolt pattern | Center bore | OE wheel |
|---|---|---|---|---|
| 2024 | Cadillac XT4 | 5x120 | 66.9 mm | 18x8J ET42 |
| 2019 | Cadillac XT4 | 5x120 | 66.9 mm | 18x8.0J |
Factory wheel sizes on the Cadillac XT4
Across the 2 Cadillac XT4 trims with a documented factory wheel, the OE diameter is 18 inch, width 8J and offset ET42. A forged wheel that keeps the 5x120 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 XT4 (5x120, 66.9 mm Bore)
In our database, 136 other vehicle entries from 9 makes use exactly the same 5x120 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.
5x120 is used by 10.3% of the vehicle entries in our database (667 of 6,503); 24.1% 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 XT4?
The Cadillac XT4 uses a 5x120 bolt pattern with a 66.9mm center bore across every XT4 variant in our database (2 guides, 2019–2024).
What is the Cadillac XT4 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 XT4 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 XT4?
Any wheel drilled 5x120 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.
