If you are a car enthusiast, you might have heard of the term “hub ring” or “hub centric ring”. But what exactly is a hub ring and why do you need one? In this article, we will explain everything you need to know about hub rings, including their definition, function, benefits, drawbacks, and alternatives.

A hub ring is a circular device that fits between the wheel hub and the wheel center bore. The wheel hub is the part of the car that connects the wheel to the axle, while the wheel center bore is the hole in the center of the wheel that allows it to fit over the hub. The hub ring is designed to fill the gap between the hub and the bore, ensuring a snug and secure fit.

The main purpose of a hub ring is to center the wheel on the hub, which prevents vibration, wobbling, and uneven wear. A hub ring also helps to distribute the weight of the car evenly across the wheel, which improves the handling and performance of the vehicle.

Hub rings are usually made of plastic or metal, such as aluminum or steel. Plastic hub rings are cheaper and easier to install, but they are more prone to cracking and melting under high temperatures. Metal hub rings are more durable and resistant to heat, but they are more expensive and harder to remove.

Hub rings come in different sizes and shapes, depending on the type and model of the car and the wheel. The size of the hub ring is determined by two measurements: the inner diameter and the outer diameter. The inner diameter is the size of the wheel hub, while the outer diameter is the size of the wheel center bore. The hub ring should match these two measurements exactly, otherwise it will not fit properly.

Hub rings are also classified into two types: universal and vehicle-specific. Universal hub rings are designed to fit any car and wheel combination, as long as the inner and outer diameters are compatible. Vehicle-specific hub rings are tailored to fit a specific car and wheel model, ensuring a perfect fit and alignment.

Why Do You Need a Hub Ring?

You might be wondering why you need a hub ring in the first place. After all, shouldn’t the wheel fit the hub perfectly without any gap? Well, the answer is not always.

The reason why there is a gap between the hub and the bore is because of the way wheels are manufactured. Wheels are mass-produced in factories, and they are designed to fit a wide range of cars and models. Therefore, they have to accommodate different hub sizes and shapes, which means they have to have a larger center bore than the hub. This allows the wheel to fit over any hub, regardless of the size and shape.

However, this also means that the wheel is not centered on the hub, which can cause problems. If the wheel is not centered, it will not rotate smoothly and evenly, which can lead to vibration, wobbling, noise, and uneven wear. This can affect the comfort, safety, and performance of the car, as well as the lifespan of the wheel and the tire.

This is where the hub ring comes in. By filling the gap between the hub and the bore, the hub ring centers the wheel on the hub, which eliminates the vibration, wobbling, noise, and uneven wear. This improves the ride quality, handling, and performance of the car, as well as the durability of the wheel and the tire.

How to Choose the Right Hub Ring?

If you want to use a hub ring for your car and wheel, you need to choose the right one. Choosing the wrong hub ring can cause more harm than good, as it can damage the wheel, the hub, or the car itself. Here are some tips on how to choose the right hub ring:

First, you need to measure the inner and outer diameters of your hub and bore. You can use a caliper, a ruler, or a tape measure to do this. Make sure you measure accurately and precisely, as a small difference can make a big difference in the fit and function of the hub ring. You can also check the specifications of your car and wheel online or in the manual, as they might have the measurements listed there.
Second, you need to decide whether you want a plastic or a metal hub ring. Plastic hub rings are cheaper and easier to install, but they are more prone to cracking and melting under high temperatures. Metal hub rings are more durable and resistant to heat, but they are more expensive and harder to remove. You can choose the one that suits your budget and preference, but make sure you check the quality and compatibility of the material before buying.
Third, you need to decide whether you want a universal or a vehicle-specific hub ring. Universal hub rings are designed to fit any car and wheel combination, as long as the inner and outer diameters are compatible. Vehicle-specific hub rings are tailored to fit a specific car and wheel model, ensuring a perfect fit and alignment. You can choose the one that suits your availability and convenience, but make sure you check the fitment and alignment of the hub ring before installing.

How to Install a Hub Ring?

Installing a hub ring is not a difficult task, but it requires some care and attention. Here are the steps on how to install a hub ring:

First, you need to clean the hub and the bore of any dirt, dust, grease, or rust. You can use a cloth, a brush, or a spray to do this. Make sure you remove any debris or residue that might interfere with the fit and function of the hub ring.
Second, you need to align the hub ring with the hub and the bore. You can use a marker, a tape, or a tool to do this. Make sure you align the hub ring correctly, as a wrong alignment can cause damage or malfunction.
Third, you need to insert the hub ring into the bore. You can use your hands, a hammer, or a tool to do this. Make sure you insert the hub ring gently and firmly, as a loose or tight fit can cause problems. You should hear a click or a snap when the hub ring is in place.
Fourth, you need to mount the wheel over the hub and the hub ring. You can use your hands, a jack, or a tool to do this. Make sure you mount the wheel securely and evenly, as a misaligned or unstable wheel can cause issues. You should tighten the lug nuts or bolts in a star pattern, using a torque wrench or a tool to do this. You should follow the recommended torque specifications for your car and wheel, as over-tightening or under-tightening can cause damage or failure.

What are the Benefits of Using a Hub Ring?

Using a hub ring can have several benefits for your car and wheel, such as:

Improving the ride quality, handling, and performance of the car, as the wheel is centered and balanced on the hub, which prevents vibration, wobbling, noise, and uneven wear.
Extending the lifespan of the wheel and the tire, as the weight of the car is distributed evenly across the wheel, which reduces the stress and friction on the wheel and the tire.
Enhancing the appearance and style of the car and the wheel, as the hub ring fills the gap between the hub and the bore, which creates a seamless and sleek look.

What are the Drawbacks of Using a Hub Ring?

Using a hub ring can also have some drawbacks for your car and wheel, such as:
