En artikkel for å forstå hjulparametrene

One article to understand the wheel parameters, we are old drivers

It is said that 80% of the modification enthusiasts in this world start from changing the wheels. A lot of car enthusiasts, in the early stage of modification of the car, are planning to change a set of very personalized wheels. But when they see the wheel data, they are often confused, what is the J value? The ET value is what? This issue, the small magnesium to popularize for you, the wheel of several key data, I hope to help you all.

Hub parameters generally include: diameter, width (J value), PCD and hole position, offset (ET value), center hole.

1、Diameter

It refers to the diameter of the wheel, usually the number behind the tire R also represents the diameter of the wheel matched by the tire, and his unit is inch.

The width of the wheel is the distance between the flange on both sides of the wheel in inches, usually called the J-value. For example, the width of a 9J wheel is 9 inches. The width of the wheel has a direct impact on the choice of tire. With different J-values for the same size tire, the choice of flat ratio and width will be different.

3、Pore Distance (PCD)

PCD is the pitch circle diameter, refers to the wheel hub screw hole connected to a circle, the diameter of this circle is the wheel PCD. General wheel most of the hole position is 5 bolts and 4 bolts, trucks are 8 or 10. The distance of the bolts varies, so we often hear the names 4X103, 5X114.3, 5X112. 5X114.3, for example, means that the PCD of the wheel is 114.3 mm, with 5 bolts in the hole. When choosing a wheel, PCD is one of the most important parameters, for safety and stability considerations, it is best to choose a wheel with the same PCD as the original car to upgrade the transformation Oh ~.

4、Wheel offset (ET value)

The offset (also called offset or ET value) refers to the distance from the hub centerline to the mounting surface, generally in mm. the final position of the hub is the structure of the ET value and J value together. There are now also many wheel calculation tools available online to perform the calculation.

 

5. Center Hole

This is better understood as the round hole in the center of the back of the wheel. Many trucks have a center hole in the role of more than 200, and small cars are around 50-60. We also need to refer to this value when choosing a new wheel, which must be larger than this value before the wheel is available.

Finally, we also want to remind you that wheel replacement must be based on the data of your own vehicle to ensure the normal use of the wheels, as well as the safety and stability of the vehicle in the driving process.
