67.1 mm to 57.1 mm Hub-Centric Rings: Sizing and Fitment Guide

A hub-centric ring for a 67.1 mm wheel center bore and a 57.1 mm vehicle hub should have:

• Outside diameter (OD): 67.1 mm
• Inside diameter (ID): 57.1 mm

In other words, the ring fits inside the wheel’s center bore and around the vehicle’s hub pilot. For this application, the correct sizing direction is 67.1 mm → 57.1 mm, provided the dimensions refer to wheel bore first and vehicle hub second.

Confirm the wheel center bore: 67.1 mm

The wheel center bore is the machined opening in the back of the wheel. It is not the wheel’s bolt-hole diameter, PCD, or the diameter of the visible center-cap opening.

For a hub-centric ring to seat correctly, the ring’s outside diameter must match the wheel center bore. If the wheel bore is 67.1 mm, select a ring with a nominal 67.1 mm OD.

Before ordering, confirm the bore from one or more reliable sources:

• Wheel markings or manufacturer specifications
• The wheel’s technical documentation
• A measurement taken with a suitable caliper
• A measurement of the straight, cylindrical section of the bore

Avoid measuring over a chamfer or rounded entry edge. The nominal bore may be 67.1 mm even though the opening appears slightly larger at the outer edge because of the chamfer.

Also check whether the wheel has a stepped, tapered, or unusually shallow center bore. A standard ring may require a continuous cylindrical seating area. The wheel must have enough bore depth for the ring to engage securely without interfering with the wheel’s rear face or center-cap structure.

Confirm the vehicle hub pilot: 57.1 mm

The vehicle hub pilot is the raised cylindrical section that enters the center bore of the wheel. It is different from the wheel bore and may be specified separately by the vehicle or hub manufacturer.

For this fitment, the ring’s inside diameter must match the vehicle hub pilot, nominally 57.1 mm.

Confirm that 57.1 mm refers to the actual hub pilot diameter, not:

• The brake rotor center opening
• A dust cap or protective cover
• A nearby shoulder on the hub
• A nominal specification measured at a different point

The hub should be clean and free of rust buildup before measuring. Corrosion can make a hub appear larger and can prevent the ring from sliding fully into place. If the hub has a chamfer or radius, measure the usable cylindrical pilot rather than the angled transition.

The hub pilot must also protrude far enough to engage the ring and wheel. A ring with the correct ID and OD cannot compensate for a hub pilot that is too short, obstructed, or shaped differently from the ring’s internal profile.

Why the ring OD matches the wheel and the ID matches the hub

An aftermarket wheel with a larger center bore can fit over a smaller vehicle hub, but it is not hub-centric unless the gap is filled. A hub-centric ring fills that radial gap and helps center the wheel during installation.

For a 67.1 mm wheel bore and 57.1 mm hub:

\[ \text{Ring OD} = 67.1\text{ mm} \]

\[ \text{Ring ID} = 57.1\text{ mm} \]

The nominal radial wall thickness is:

\[ \frac{67.1 - 57.1}{2} = 5.0\text{ mm} \]

That 5.0 mm figure describes the radial difference on each side, not the ring’s axial width or the amount of hub engagement. The ring’s actual geometry may include chamfers, a lip, a step, or other features.

A hub-centric ring is intended to locate the wheel on the vehicle hub. It does not correct an incorrect bolt pattern, offset, wheel load rating, brake-clearance problem, thread engagement issue, or wheel-seat mismatch. Those specifications must be checked independently.

Check nominal sizing and manufacturing tolerance

Hub rings are precision fitment parts, but the listed dimensions are generally nominal. A ring that is excessively tight may not install fully; one that is noticeably loose may not center the wheel reliably.

Before selecting a ring, match these specifications:

Do not assume that a listing written as “57.1 to 67.1” uses the same direction as “67.1 to 57.1.” Retailers may list ID first, OD first, or use vehicle hub size followed by wheel bore. Read the detailed specification and confirm which number is the inside diameter and which is the outside diameter.

If your measured dimensions differ slightly from the published nominal sizes, investigate the reason before ordering. The difference may result from measurement location, chamfers, paint, corrosion, or a different wheel or hub version.

Choose a suitable ring material

Hub-centric rings are commonly made from engineered plastic or metal, but material alone does not determine fitment quality. Match the ring’s dimensional accuracy, profile, and service suitability to the application.

Consider:

• Operating temperature near the wheel and brake assembly
• Exposure to water, road salt, and winter corrosion
• Whether the ring is intended for repeated wheel removal
• The manufacturer’s stated dimensional tolerance
• Compatibility with the wheel and hub materials

Metal rings can develop corrosion that makes removal difficult or causes the ring to bind to the hub. Plastic rings may be easier to remove and more resistant to some forms of corrosion, but they still need to be correctly rated and dimensioned. Do not modify a ring by sanding its ID or OD unless the manufacturer specifically permits it; removing material can create an inaccurate or uneven fit.

Installation and corrosion checks

Install the ring only after confirming the wheel and hub dimensions. A typical fitment check is:

1. Remove rust, dirt, paint buildup, and debris from the hub pilot and wheel center bore.
2. Inspect the ring for cracks, burrs, distortion, or damaged chamfers.
3. Test-fit the ring on the clean hub by hand.
4. Confirm that it seats fully and evenly against the intended shoulder.
5. Test-fit the wheel and verify that the ring enters the wheel bore without forcing the wheel into position.
6. Make sure the ring does not prevent the wheel from sitting flush against the hub or rotor mounting face.
7. Install and torque the wheel fasteners according to the vehicle and wheel manufacturer’s instructions.
8. Recheck the wheel after initial use as required by those instructions.

Do not hammer a ring into place or use the wheel fasteners to pull a misaligned wheel onto the hub. That can indicate an incorrect diameter, an incompatible profile, corrosion, or interference elsewhere.

Avoid applying thick grease or heavy anti-seize to the seating surfaces. These products can attract debris, alter the effective fit, or make the ring difficult to control during installation. If a corrosion-prevention product is used, it should be applied sparingly and only where compatible with the hub, wheel, and ring manufacturer’s guidance. Keep mating faces and threaded fasteners free from contamination unless a specified lubricant is required.

67.1-to-57.1 product-selection checklist

Before purchasing a hub-centric ring, confirm all of the following:

• The wheel center bore is 67.1 mm.
• The vehicle hub pilot is 57.1 mm.
• The listed ring OD is 67.1 mm.
• The listed ring ID is 57.1 mm.
• The listing clearly identifies whether dimensions are ID or OD.
• The ring profile fits the wheel’s bore depth and chamfer.
• The hub has sufficient clean cylindrical pilot for the ring.
• The ring will not interfere with the wheel, brake assembly, or center cap.
• The material and temperature rating suit the vehicle’s use.
• Wheel bolt pattern, offset, load rating, fastener seat, and clearance have been checked separately.

For this specific sizing requirement, the essential direction is wheel bore 67.1 mm on the outside of the ring, vehicle hub 57.1 mm through the inside of the ring.
