JAC T9 wheel specs by year and trim
| Year | Model / trim | Bolt pattern | Center bore | OE wheel |
|---|---|---|---|---|
| 2025 | JAC T9 | 6x139.7 | 106.1 mm | 18x8J |
| 2023 | JAC T9 | 6x139.7 | 106.1 mm | 18x8J |
Factory wheel sizes on the JAC T9
Across the 2 JAC T9 trims with a documented factory wheel, the OE diameter is 18 inch, width 8J. A forged wheel that keeps the 6x139.7 bolt pattern and the 106.1 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 JAC T9 (6x139.7, 106.1 mm Bore)
In our database, 31 other vehicle entries from 6 makes use exactly the same 6x139.7 bolt pattern and 106.1 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.
6x139.7 is used by 4.0% of the vehicle entries in our database (258 of 6,503); 12.8% of those also use a 106.1 mm center bore.
Hub-Centric Rings for a 106.1 mm Center Bore
A wheel with a center bore larger than 106.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 108.1 mm | 108.1 → 106.1 mm |
| 110.1 mm | 110.1 → 106.1 mm |
| 130.1 mm | 130.1 → 106.1 mm |
ANKUSI forged wheels are bored to exactly 106.1 mm for this vehicle, so no ring is needed.

FAQ
What is the bolt pattern on a JAC T9?
The JAC T9 uses a 6x139.7 bolt pattern with a 106.1mm center bore across every T9 variant in our database (2 guides, 2023–2025).
What is the JAC T9 center bore?
The hub-centric center bore is 106.1 mm. Aftermarket wheels should match this bore or use hub-centric rings so the hub, not the bolts, carries the load.
Do all JAC T9 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 JAC T9?
Any wheel drilled 6x139.7 with a 106.1mm 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.
