How to measure for hub centric rings, a critical step in ensuring proper wheel fitment, is a topic that often sparks curiosity among car enthusiasts and DIY mechanics alike. These rings, often overlooked but essential, play a vital role in creating a seamless connection between your vehicle’s hub and your wheels. By understanding the importance of hub centric rings and mastering the art of measuring them, you can achieve optimal wheel fitment, minimizing vibrations and ensuring a smooth, safe ride.
Imagine cruising down the road, feeling the slight rumble beneath your feet, a constant reminder that something isn’t quite right. This unsettling vibration, a common symptom of improper wheel fitment, can stem from a lack of hub centric rings or incorrectly sized ones. By delving into the world of hub centric rings, we’ll unravel the mysteries behind their function, learn how to measure for them accurately, and ultimately, achieve a perfect wheel fitment that enhances both performance and driving pleasure.
Understanding Hub Centric Rings
Hub centric rings are essential components in ensuring proper wheel fitment and vehicle safety. These small, precisely-machined rings are designed to bridge the gap between the vehicle’s hub and the wheel’s center bore, ensuring a secure and centered fit.
Purpose of Hub Centric Rings
Hub centric rings play a crucial role in wheel fitment, ensuring that the wheel is properly centered on the vehicle’s hub. The rings’ precise dimensions create a snug fit between the wheel’s center bore and the vehicle’s hub, eliminating any potential for wobble or misalignment. This centered fit is critical for safe and comfortable driving, as it prevents the wheel from vibrating or shaking, which can lead to premature wear and tear on other components.
Potential Problems with Incorrect Hub Centric Rings
Using incorrect hub centric rings or neglecting them altogether can lead to a range of problems:
- Wheel Wobble: A misaligned wheel can cause noticeable vibration and shaking, particularly at higher speeds. This can lead to a rough ride, uneven tire wear, and potential damage to suspension components.
- Premature Wear: The constant vibration and stress on the wheel and suspension components can lead to premature wear and tear, requiring costly repairs.
- Safety Hazards: A wheel that is not properly centered can come loose or detach entirely, posing a serious safety risk.
- Reduced Performance: Wheel wobble can negatively impact handling and performance, making the vehicle less responsive and harder to control.
Types of Hub Centric Rings
Hub centric rings come in various sizes and materials, depending on the specific application:
- Aluminum: Lightweight and commonly used for most applications.
- Steel: More durable and suitable for heavy-duty vehicles or demanding applications.
- Plastic: Affordable and often used for light-duty vehicles or temporary applications.
The size of the hub centric ring is determined by the difference between the vehicle’s hub bore and the wheel’s center bore. For example, a vehicle with a 66.6mm hub bore and a wheel with a 73mm center bore would require a 6.4mm hub centric ring.
Always consult your vehicle’s owner’s manual or a reputable online resource to determine the correct hub centric ring size for your vehicle.
Measuring Your Vehicle’s Hub Bore: How To Measure For Hub Centric Rings

Measuring the hub bore diameter is crucial for determining the correct size of hub centric rings. This measurement ensures the wheel is properly centered on the hub, preventing vibrations and improving overall driving experience.
Measuring the Hub Bore Diameter, How to measure for hub centric rings
To accurately measure the hub bore diameter, follow these steps:
- Locate the hub: The hub is the central part of the wheel that attaches to the vehicle’s axle. It’s usually a metal cylinder with a hole in the center.
- Clean the hub: Ensure the hub is clean and free of any debris that might interfere with the measurement. Use a clean cloth or brush to remove any dirt or rust.
- Use a caliper or measuring tape: A caliper is the most accurate tool for this measurement. If using a measuring tape, make sure it’s flexible and can reach into the hub bore.
- Position the caliper or tape: Carefully insert the caliper jaws or the measuring tape into the hub bore. Ensure they are fully extended and touching the inner walls of the hub bore.
- Read the measurement: Read the measurement from the caliper or measuring tape. This measurement represents the diameter of the hub bore.
Tip: For the most accurate measurement, repeat the process multiple times and take the average.
Determining the Required Hub Centric Ring Size

The hub centric ring size is determined by the difference between the vehicle’s hub bore and the wheel’s center bore. To ensure a proper fit and prevent vibrations, the hub centric ring must precisely fill the gap between these two dimensions.
Calculating the Required Hub Centric Ring Size
The required hub centric ring size is calculated by subtracting the vehicle’s hub bore from the wheel’s center bore.
Hub Centric Ring Size = Wheel Center Bore – Vehicle Hub Bore
For example, if a vehicle has a hub bore of 66.6 mm and the wheel has a center bore of 73 mm, the required hub centric ring size would be:
73 mm – 66.6 mm = 6.4 mm
Therefore, you would need a 6.4 mm hub centric ring to ensure a proper fit.
Hub Centric Ring Size Chart
The following table summarizes the relationship between hub bore, center bore, and the required hub centric ring size:| Vehicle Hub Bore (mm) | Wheel Center Bore (mm) | Required Hub Centric Ring Size (mm) ||—|—|—|| 66.6 | 73 | 6.4 || 56.1 | 66.6 | 10.5 || 64.1 | 73 | 8.9 || 67.1 | 73 | 5.9 || 57.1 | 73 | 15.9 |It’s crucial to use the correct hub centric ring size to ensure proper wheel fitment and prevent damage to the vehicle’s hub or wheel.
Installing Hub Centric Rings

Installing hub centric rings is a relatively straightforward process that can be done with basic tools and a bit of mechanical aptitude. However, it’s essential to follow the correct steps and safety precautions to ensure a successful and safe installation.
Tools Needed for Installing Hub Centric Rings
Before beginning the installation, gather the following tools:
- Torque wrench
- Socket set
- Lug wrench
- Jack and jack stands
- Cleaning cloth
- Grease or anti-seize compound
Installing Hub Centric Rings
Once you have the necessary tools, follow these steps to install the hub centric rings:
- Loosen the lug nuts: Using your lug wrench, loosen the lug nuts on the wheel you’ll be working on. Do not remove the nuts completely at this stage.
- Jack up the vehicle: Use your jack to raise the vehicle until the tire is off the ground. Secure the vehicle with jack stands for safety.
- Remove the wheel: Now that the vehicle is safely supported, remove the lug nuts and take off the wheel.
- Clean the hub: Use a cleaning cloth to remove any dirt, debris, or rust from the hub.
- Install the hub centric ring: Carefully place the hub centric ring onto the hub, ensuring it sits flush against the hub face.
- Install the wheel: Place the wheel back onto the hub, aligning the wheel studs with the holes in the wheel.
- Tighten the lug nuts: Hand-tighten the lug nuts until the wheel is snug.
Then, use your torque wrench to tighten the lug nuts to the manufacturer’s specified torque.
- Lower the vehicle: Once the lug nuts are properly tightened, lower the vehicle and remove the jack stands.
- Repeat for other wheels: Repeat steps 1-8 for each wheel that needs a hub centric ring.
Safety Precautions
It’s crucial to prioritize safety when working on your vehicle. Here are some essential safety precautions to follow:
- Always use jack stands: Never rely solely on a jack to support your vehicle. Always use jack stands to secure the vehicle before working underneath it.
- Chock the wheels: Before jacking up the vehicle, chock the wheels on the opposite side to prevent the vehicle from rolling.
- Work on a level surface: Ensure your vehicle is parked on a level surface before jacking it up.
- Use appropriate safety gear: Wear safety glasses and gloves to protect yourself from potential hazards.
- Be aware of your surroundings: Be aware of your surroundings and ensure there are no obstructions around the vehicle.
Best Practices for Installing Hub Centric Rings
- Clean the hub thoroughly: Ensure the hub is clean and free of any debris or rust before installing the hub centric ring. This will help ensure a proper fit and prevent any potential issues.
- Use a torque wrench: Always use a torque wrench to tighten the lug nuts to the manufacturer’s specifications. Over-tightening the lug nuts can damage the wheel studs or the hub.
- Check for proper fit: After installing the hub centric ring, check to ensure it fits snugly against the hub face. If it’s loose or doesn’t fit properly, it may need to be replaced.
