CB

Each wheel has a center hole, but the diameter of the center hole is different on different wheels.The center hole diameter is used to indicate the size of the center hole of the wheel.In the modification, if the diameter of the center hole of the modified wheel is different from the original factory value of the vehicle, it can be installed by installing a positioner.However, due to the transposition of the modifier, the ability to deal with the bumpy road conditions in the actual driving will be correspondingly reduced.

PCD

This is an important parameter when selecting a wheel, also known as the pitch circle diameter.PCD parameter is used to indicate how many mounting holes the wheel has and what the diameter of the mounting holes is.For example, the PCD value of a wheel is 5x120mm, which means that the wheel has 5 locating bolts and the mounting diameter is 120mm.

ET

The offset is also called ET value, which has positive and negative points.The ET value of conventional original models is generally positive, that is, the fixed surface of the wheel is within the center surface, otherwise, the ET value is negative, and the negative ET value is called the negative wheel.

Width (J)

It is often said that the width of a wheel is 7J and 8J, and the number here represents the width of the wheel, while J just represents the shape and height of the flange of the wheel. In addition to J, we also have C, JJ, JK, K, etc., which are mainly different from the height of the bump. C is the lowest, K is the highest, and J is the most common type of wheel.7J, for example, means that the distance between the flanges on the wheel is 7 inches.
