What is hub center bore?
The centerbore of a wheel is the machined opening on the back of the wheel that centers the wheel properly on the hub of a vehicle. This hole is machined to exactly match the hub so the wheels are precisely positioned as the lug hardware is torqued down. These are known as lug centric wheels.
Does hub bore matter on wheels?
The relation between wheel centre bore and hub diameter Wheel hubs, located between the drive axle and brake drums, connect the wheels to the body of the car. Therefore, in order to fit the new wheels correctly, it is important that the car’s wheel hub size perfectly matches the wheel’s centre bore.
What happens if you don’t use hub centric rings?
If you don’t use hub centric rings, you transfer the weight of the vehicle to the lug hardware, and the wheel studs will break. Fact is, the hub centric rings do not bear a load. The weight of the vehicle is actually supported by the friction between the wheel and its mounting surface on the axle.
Can the center bore be bigger?
Re: centre bore too big = dangerous? Yeah as long as you don’t get a vibration, you should be alright. As soon as it starts to vibrate, it’s dangerous. You could also get hubcentric rings pretty cheap.
How is center bore measured?
The center bore measurement of a wheel is the size of the hole on the backside of the wheel, usually measured in millimeters (mm). In some countries, this is also referred to as spigot size. When shopping for wheels or hub centric rings, it’s important to know the center bore of the wheels.
How do you find center bore?
Here’s a picture of the inside of a wheel, the center bore is the hole in the center of the five bolt holes / lug nut holes which goes around it. Wheel center bore as seen from the inside of the rim. The center hole diameter is easy to measure, use a measuring tape or a caliper, which the latter is more preferred.
Can you run wheels without hub centric rings?
Do I need Hubcentric Rings or Hubcentric Adapters? Yes, if your wheel center bore is a larger diameter than your hub bore, you absolutely need hubcentric rings.

What is my hub bore size?
The outer diameter is the hub bore, while the inner diameter is the diameter of the vehicle hub itself. For example: a hub-centric ring size of 73-67.1 would mean that the wheel center bore is 73 mm wide and the vehicle hub is 67.1 mm wide.
What happens if the center bore is larger than the hub?
On the other hand, if the center bore is larger than the diameter of the hub, the wheel can be fitted, but unwanted diameter differences will be problematic. Fortunately, many issues related to the difference in hub diameter and wheel centre bore size can be solved with wheel spigot rings.
Do aftermarket wheels need hub centric rings?
While this may be the case, your aftermarket wheels may still need hub centric rings to fit properly.

What is the centre bore of a wheel?
The centre bore, (also known as spigot size), is the diameter of this hole, usually measured in millimetres. For most road wheels, the weight of the car is transmitted from the spigot, (the bit the centre of the wheel that protrudes from the hub), to the centre hole in the wheel. The job of the wheel studs or wheel bolts is to hold…
