It is said that a part called a hub ring is effective to prevent rattling and loosening of nuts when installing tire wheels from outside the company. Is it really necessary to install a hub ring? I will explain how to choose a hub ring and its necessity and effect.

The hub ring is a part for fixing the external wheel to the center.

You may have heard that when you replace a genuine wheel that was originally installed in a car with an external product, you should install a metal or resin part called a hub ring. This is a part to fill the gap between the center hole of the wheel and the center hub on the car side, and it is said to have the effect of preventing vibration during running and loosening of the wheel nut.

Is a hub ring necessary for external wheels?
The hub ring must be selected according to the diameter of the center hole of the wheel and the diameter of the hub center on the car side.

So why do we need these parts? Originally, genuine wheels are made so that the center hole in the center of the wheel matches the center hub on the car side (although there are some exceptions…). Therefore, when the wheel is placed on the hub, the wheel can be mounted in the center of the hub surface with some accuracy.

Especially in imported cars, bolts are not struck on the hub side, but in cars where the bolts are tightened from the wheel side, the wheel must be installed unless the wheel is firmly set in the center of the hub. I can’t even stay. Even in domestic cars, genuine aluminum wheels such as Toyota and Mitsubishi often use flat seat nuts instead of the general 60 degree taper nuts, and I think that it is quite difficult to install if the center does not fit.

However, in the case of external wheels, the center hole of the wheel is wide open, so if you try to match it with the hub center on the car side, it will not fit at all. This is because the diameter of the hub center on the car side differs depending on the manufacturer and model, so it is designed so that it can be installed in many cars by making a large hole in advance.

However, 60-degree tapered nuts are often used for external wheels, and in many cases, if the nuts are tightened evenly, the center will come out firmly, but depending on the type of wheel, etc. , It seems that there are cases where the center does not come out firmly just by tightening the nut to the about, the nut is easy to loosen, and vibration occurs during running.

In such a case, the hub ring that fills the gap between the center hole of the wheel and the hub center and makes it easier to set the wheel in the center of the hub becomes effective.

Basically, tighten the taper nut evenly to get the center out.

By using the hub ring to match the diameter of the center hole on the wheel side with the diameter of the hub center, it is certainly easier for the wheel to attach to the center of the hub. However, the hub ring is not made with such tight dimensions, so there is a slight gap even if it is fitted to the wheel. In other words, in a strict sense, the wheel does not come to the center only with the hub ring.

It is still the role of the nut (or bolt) to align the wheel firmly with the center of the hub. It is certainly effective to set the wheel near the center in advance using a hub ring, but in the end it is important to tighten it firmly with nuts. If the nuts tend to loosen or vibrate without the hub ring, it may be possible to improve by reviewing the nut tightening method.

To set the wheel exactly in the center of the hub, first tighten each nut until it turns by hand. From there, use a torque wrench to tighten with a torque of about half the specified value (about 50 Nm for domestic cars), then 2/3 torque, and finally tighten with the specified value, and so on. I will do it with the image of multiplying. The order of tightening is to tighten the nuts diagonally according to theory alternately. It’s a hassle, but it allows you to set the wheel more accurately in the center of the hub.

Be careful of sticking when installing the hub ring

By the way, what you should be careful about when using the hub ring is the sticking of the hub ring. If you leave the hub ring on for a long time, the rust can cause the hub and hub ring to stick together and become stuck. There is no problem with reattaching the removed wheel, but if the hub ring does not come off when trying to return to the genuine wheel or when installing the temper tire, it will be difficult

When using a metal hub ring
When using a metal hub ring, there is a risk that the ring will stick to the hub side in this way.

The hub ring is designed for external wheels with large center holes, so basically it does not fit into genuine wheels. If you try to install it forcibly, it will put a burden on the wheel and hub bolt, and if you drive with a genuine wheel without noticing that the hub ring remains, there is a risk that the wheel will fall off in the worst case. is.

Therefore, before installing the hub ring, it is essential to take measures such as removing rust on the hub surface (although the hub still rusts), and regular maintenance is also essential. Also, if you are worried about the hub ring sticking, you can also install a resin hub ring. In terms of durability, it is not as good as metal (mainly aluminum), but there is no worry of rusting.
