About The Measurement on Wheel

R value

The R value we often hear refers to the size of the wheel hub, which is the difference between 18 inches, 19 inches, and 20 inches. The correct way to measure the size should be to start with the wheel bead.

J value

The J value is actually very simple. It refers to the width of the cross section of the wheel hub. The size of the J value will affect the size of the tire. Generally speaking, the larger the J value, the larger the tire tread and the stronger the grip. 

ET value

The ET value is also called Offset, which is one of the more important hub data. The ET value refers to the distance between the hub mounting surface and the center-line. 

Hub X distance

This data is mainly related to the space of the caliper, so if you want to replace the big caliper, you must pay more attention to this data. 

Hub center hole

This is easier to understand. The center hole of the hub is in the center of the hub, which is used to connect and fix the car. The data of the center hole of the hub is very important. If you do not pay attention to it, there may be a dilemma that the hub cannot be installed.
