How to measure hub centric rings

Step 2: measuring your wheel's center bore (outer diameter)

The second measurement is the diameter of the large hole in center of your wheel. sort of, this will determine theOuter Diameter (OD)of your hub centric ring.

Here's how to get measurement:

Place the wheel face down on a soft, protected surface to avoid scratches.
Locate the center hole on the back of the wheel. Clean this area thoroughly, ensuring there is no debris that could affect your measurement.
Using the inside-measuring jaws of your caliper, measure the diameter of this hole. I think, as before, take several measurements across different points of the circle to ensure accuracy and account for any minor imperfections.
Record the most consistent measurement. This is your wheel's center bore and the required OD of the hub centric ring.

Frequently asked questions

What happens if I don't use hub centric rings with aftermarket wheels?

Without hub centric rings, the wheel is not properly centered on the hub, relying only on the lug nuts for alignment. This can cause persistent vibrations, uneven tire wear, and excessive stress on the wheel studs, which could lead to a catastrophic failure over time. — more or less

Are plastic or metal hub centric rings better?

by the way, both have their advantages, right? High-quality polycarbonate (plastic) rings are the most common. They are inexpensive, do not corrode, and will not seize to the hub or wheel. Aluminum (metal) rings are more durable and less prone to damage during installation, but they can corrode and fuse to the hub or wheel in harsh climates if not installed with anti-seize compound.

Can I just measure with a ruler or tape measure?

is strongly advised not to, It does. (well, almost) A ruler is not precise enough for this task, right? The gap you are trying to fill is often only a few millimeters wide, and an error of even half a millimeter can prevent the ring from fitting or cause it to... A digital or vernier caliper is the only tool that provides the required accuracy.

Finalizing your hub centric ring size

You now have the two key dimensions needed to purchase... The size is always expressed as the Outer Diameter (OD) first, followed by Inner Diameter (ID), typically in millimeters.

For example, if you measured your wheel's center bore to be 73.1 mm and your vehicle's hub bore to be 57.1 mm, you need to purchase set ofas far as I can tell, 73.1 x 57.1 mmhub centric rings.

Double-check your written measurements before ordering. or rather This simple, precise process is the most reliable way to guarantee a great, vibration-free fitment for your aftermarket wheels.
