What is wheel center bore?

Vlada June 06 2022

A wheel's center bore is the hole in the center of the wheel that attaches to the hub. The size of the hole varies depending on the make and model of the car. Most wheels have a standard size center bore, but some manufacturers use a different size to accommodate their own hubs. It's important to know the size of your vehicle's center bore so that you can choose a wheel with the correct fit.

If you're unsure of your car's center bore size, you can measure it yourself or look it up in the manufacturer's documentation. Once you know the size, you can choose a wheel with the same or a similar size. If you choose a wheel with a smaller center bore, you may be able to use adapters to make it fit. However, it's generally not recommended to use a wheel with a larger center bore on your car.

When shopping for wheels, be sure to pay attention to the listed center bore size. This will ensure that you choose a wheel that's compatible with your car.

How important is center bore size?

It's difficult to install new wheels on a hub with a big hub collar. If the diameter of the hub collar is greater than the central bore, it will be impossible to fit the new wheels. However, if the center bore is larger than the diameter of the hub, there is a potential for the wheel to become loose and fall off. For this reason, it's important to make sure that you choose wheels with the correct center bore size for your car.

Is it safe to drive without hub centric rings?

If you don't use hubcentric rings, the weight of the car is transferred to the lug hardware, and the wheel studs will break. In reality, the hubcentric rings do not support any weight. The friction between the tire and its axle mounting surface serves to support the vehicle's weight.

How do I find my wheel center bore?

  • Place the wheel face down on a flat surface. Make sure the lip isn't damaged.
  • Scrub the rims with a brush and a vacuum, then use the Tare Caliper to check for measurement accuracy. When fully closed, make sure the caliper reads "0.00."
  • Using the "Inside diameter" function, measure. The surface of your caliper is meant to measure the inside diameter of a wheel.

Is center bore and hub bore the same?

The terms "hub bore" and "center bore" are often used interchangeably, but they're not actually the same thing. Hub bore refers to the diameter of the hole in the hub, while center bore refers to the diameter of the hole in the center of the wheel. Generally speaking, the hub bore will be slightly smaller than the center bore. That's because the hub needs to be a tight fit on the wheel so that it doesn't come loose.

What is my hub bore size?

The hub bore is the diameter of the hole in the hub. It's important to choose a wheel with the correct hub bore size so that it fits snugly on the hub. If the hub bore is too small, the wheel may not stay securely attached. If the hub bore is too large, there may be too much space between the hub and the wheel, which could cause the wheel to become loose and fall off.

To find out your hub bore size, you can measure it yourself or look it up in the hub bore size chart. Once you know the size, you can choose a wheel with the same or a similar size.

Does hub bore size matter?

The hub diameter is just as critical when choosing new wheels, whether OEM or aftermarket. If the hub diameter is smaller than the axle, the wheel will not fit. As a result, most aftermarket wheels are constructed with larger hub diameters to ensure compatibility across a wide range of vehicles.

Conclusion

The hub bore is an important measurement to be aware of when shopping for new wheels. Choosing a wheel with the wrong hub bore size could result in an unsafe situation where the wheel becomes loose and falls off.
