What do you need to know about refitting the center hole reducing ring for forged wheels?

If the car owner buys a set of forged wheels to be modified, the car owner also needs to understand the CB hole, which is also a very important structure of the wheel.

The CB hole is also called the intermediate ring. In addition to the conventional hub diameter, width, number of holes, PCD value and ET value, it is the ring that is sleeved on the axle head when the hub is installed.

The forged wheel hub uses screws to fix the rim, and the middle ring is sleeved on the shaft head, which plays a fixed and stable role, that is, through the middle ring and the shaft head of the half shaft. The diameter of the original half shaft head is the same as the diameter of the original hub ring, so that the original hub can be installed.

When the car owner buys a set of hubs with a center ring smaller than the diameter of the axle head, it cannot be installed.

If a set of hubs is larger than the diameter of the axle head, another thing needs to be borrowed at this time—Wheel Center Hubring, which is the reducing ring we often hear, to fix the shaft head and the hub.
