What 6x139.7 Means & What Uses It

6x139.7 means 6 wheel studs or bolts evenly spaced on a 139.7 mm (5.5") circle, written 6x5.5 in inches. In the ANKUSI fitment database it appears on 272 vehicle variants from 27 makes, model years 1974–2027.

Most common makes: Chevrolet (50), Toyota (46), Ford (29), Nissan (23), GMC (22), Cadillac (19), Ram (13), Mitsubishi (9).

Popular models on 6x139.7: Chevrolet Silverado, Ford Ranger, GMC Sierra, Toyota Tacoma, Cadillac Escalade, Ford Bronco, Chevrolet Tahoe, Chevrolet Suburban.

Center bore is not the same across 6x139.7 vehicles: 78.1 mm (86 vehicles), 106.1 mm (31 vehicles), 93.1 mm (29 vehicles), 77.8 mm (29 vehicles). A wheel with the right bolt pattern but the wrong center bore will not seat on the hub — it needs to be machined to the exact bore or used with a hub-centric ring. Check the model page for your exact year before ordering.

Typical fastener: M14x1.5 Nut.

ANKUSI currently lists 552 forged wheel designs drilled 6x139.7, and every design can be machined to 6x139.7 with your vehicle's exact center bore and offset, in 14–24 inch diameters.

Bolt pattern alone does not guarantee a correct fit — center bore, offset, and load rating still need to be confirmed per vehicle. Check our Fitment Verification Checklist before ordering, or send us your VIN or trim level and we will confirm it for you.

Vehicles Using 6x139.7 With a 78.1 mm Center Bore

In our database, 80 other vehicle entries from 6 makes use exactly the same 6x139.7 bolt pattern and 78.1 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 pages in our English fitment guide (258 of 6,503); 31.0% of those also use a 78.1 mm center bore.

Hub-Centric Rings for a 78.1 mm Center Bore

A wheel with a center bore larger than 78.1 mm needs a hub-centric ring. The most common combinations:

Wheel bore	Ring size
84.1 mm	84.1 → 78.1 mm
93.1 mm	93.1 → 78.1 mm
100.1 mm	100.1 → 78.1 mm
106.1 mm	106.1 → 78.1 mm

ANKUSI forged wheels are bored to exactly 78.1 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.
