The correct size: 67.1 mm outer diameter × 64.1 mm inner diameter
For a wheel with a 67.1 mm center bore going onto a vehicle with a 64.1 mm hub pilot, look for a hub-centric ring specified as 67.1 mm OD × 64.1 mm ID.
The sizing direction can be easy to reverse:
- Outer diameter (OD), 67.1 mm: fits the wheel’s center bore.
- Inner diameter (ID), 64.1 mm: fits over the vehicle hub.
The ring fills the difference between the larger wheel opening and the smaller hub pilot, helping center the wheel as it is installed. Do not order a ring labeled 64.1 mm × 67.1 mm without checking which measurement the seller lists first; conventions can vary. Confirm that the listing explicitly identifies the wheel-bore side and the vehicle-hub side.
Confirm the wheel center bore
The wheel center bore is the opening at the center of the wheel’s mounting face. Confirm that it is 67.1 mm, using the wheel manufacturer’s specifications where possible. If the wheel is unmarked or the specification is uncertain, have the bore measured accurately. A casual measurement may be misleading if the opening has a chamfer, taper, coating, or other shaped edge.
Check the exact wheel, not just the vehicle application. Aftermarket wheels can have different center bores, and the same vehicle may be fitted with more than one wheel design. A ring must seat in the wheel’s actual bore; a ring that is too large will not fit, while one that is too small may not center the wheel securely.
Confirm the vehicle hub pilot
The vehicle hub pilot is the raised cylindrical section that locates the wheel at its center. Confirm its nominal diameter is 64.1 mm for the vehicle and hub configuration in question. Do not assume this measurement from the vehicle make or model alone: specifications can vary by year, trim, axle, replacement hub, or modification.
The hub pilot should be clean and free of rust scale, burrs, and debris before fitment. These can interfere with the ring’s seating or make the wheel sit unevenly. If the hub diameter or condition is uncertain, consult a qualified wheel or vehicle service professional rather than forcing a ring onto it.
How the two measurements work
The ring’s dimensions correspond to the two surfaces it fits between:
| Fitment surface | Required nominal size |
|---|---|
| Wheel center bore | 67.1 mm |
| Vehicle hub pilot | 64.1 mm |
| Hub-centric ring | 67.1 mm OD × 64.1 mm ID |
In this example, the diameter difference is 3.0 mm. That does not mean the ring is 3.0 mm thick: the difference is distributed around the circumference, so the nominal radial space is 1.5 mm per side.
The ring is for centering the wheel; it does not change the bolt pattern, offset, wheel width, or load rating. It also cannot make an otherwise incompatible wheel fit. The wheel must seat flat against the mounting face, and the correct fasteners and tightening procedure remain essential.
Check tolerances, shape, and material
The dimensions above are nominal fitment sizes. Before buying, check how the supplier states OD and ID, and confirm the ring is intended for a 67.1 mm wheel bore and 64.1 mm hub pilot. Avoid relying only on a vehicle fitment list if the wheel’s bore is unknown.
Also check the ring’s shape and depth. Some designs have a lip or flange; others are straight-sided. The ring must sit fully in the wheel bore or on the hub as intended, without preventing the wheel from contacting the hub mounting face. Confirm there is enough clearance for the hub pilot and any ring lip. A ring that is too deep, too shallow, or shaped for a different mounting arrangement may not seat correctly even if its listed diameters match.
Common materials include plastic and aluminum. Material alone does not confirm fitment: the dimensions and profile must be correct. Consider the wheel and hub’s operating conditions, the ring manufacturer’s guidance, and the likelihood of exposure to moisture, road salt, and heat. Do not modify a ring to make it fit.
Installation and corrosion checks
With the vehicle safely supported, remove the wheel and clean the hub pilot and wheel’s center bore. Remove loose corrosion and dirt without damaging the mounting surfaces. Check that the ring has no cracks, distortion, burrs, or trapped debris.
Fit the ring in its intended position–on the hub or in the wheel, depending on its design. It should seat without being forced. Then place the wheel on the hub and confirm that it sits flush against the mounting face. If the wheel rocks, hangs up, or leaves a gap, stop and check for a wrong-size ring, corrosion, an incorrect ring profile, or another obstruction.
Install and tighten the wheel fasteners using the vehicle or wheel manufacturer’s specified sequence and torque procedure. Do not use fasteners to pull a mis-seated wheel into place. Follow the manufacturer’s instructions for any post-installation torque check.
Inspect the fitment later if the vehicle is used in conditions that promote corrosion. Rust buildup can make a previously correct ring difficult to remove or interfere with a later installation. Replace a damaged or badly corroded ring rather than forcing it back into service.
Product-selection checklist
Before ordering, verify all of the following:
- Wheel center bore: 67.1 mm.
- Vehicle hub pilot: 64.1 mm.
- Ring dimensions: 67.1 mm OD × 64.1 mm ID, with OD and ID clearly identified.
- Ring profile and depth: compatible with the wheel bore and hub-pilot arrangement.
- Actual wheel and hub configuration: confirmed rather than inferred solely from vehicle model.
- Condition and installation: clean, undamaged surfaces; ring seats without force; wheel sits flush.
If the bore, hub measurement, or ring profile is uncertain, pause before purchasing. Matching the two diameters in the correct direction is the essential first step, but proper seating and verified wheel fitment matter just as much.
