my country’s regulations have made some relaxation policies for automobile modification, such as the application for change driving licenses;, reforming the style can not be modified; the body pull flowers do not exceed the 30% of the car paint can be changed.
Among them, in addition to the transition, the most modified enthusiasts are welcome, and the hub is contrast into the foot or shoes of the car. The style of the wheel is sometimes enhances the beauty of the whole car.
However, although the policy is released, the car wheel can be modified, but the regulatory restrictions are also clear. You can only change the wheel style and color, and you cannot change the size, width and other values. This is worth it. Note. However, according to regulations, only modified styles and colors, you also need to pay attention to many parameters, because if you buy a parameter, the wheel is lightly installed, and there is a security hidden danger. 
As described above, the tire size is LDQUO; R17RDQUO; and thus the hub is also a 17-inch hub.
The J value of the hub is generally in inches, and the common J value has LDQUO; 7.0jrdquo; LDQUO; 7.5jrdquo;, ldquo; 8.0jrdquo;, therefore, hub The J value is different from the tire width unit, and the value cannot be obtained from the tire, and the size and J value data need to be found inside the hub.
2, confirm the central aperture, the number of pores, and PCD
determine the outer size and width of the hub, it needs to be confirmed A lower center hole size, hole number, and PCD of the original vehicle hub.
The number of holes refers to the number of hub bolt holes. There are several bolts for the original vehicle to fix the wheel, and the hub of several apertures is required when changing the hub. 
The PCD is a circular diameter of the hub bolt hole, that is, the diameter of the bolt holes. This numerical fit hole number determines the fixation of the hub. The above three values are determined, directly determined whether the hub can be installed on the original car.
3, the hub is biased Et
In addition to the hub can be installed according to the original size When changing the hub pattern, try to select the wheel offset ET value, so there is no problem with the interference body and the steering system.
However, if the hub pitch of the hub pattern selected is different from the original car, thenCare will be carefully considered whether the vehicle is driving.
Because, the distance is the distance from the center line of the hub to the mounting surface, and the ET is LDQUO; induces depth RDQUO;, this value zero, positive or negative offset Yes, the impact is that the hub is modified or protruded outwardly.
In summary, the data cannot be ignored for the hub modification, because the hub and tires are the only part that supports the vehicle on the pavement. Wheel modification requires not only legal compliance, but also understands your hub parameters when modified, otherwise you only look at color and look, buy it is likely to be installed. 
However, in addition to the size, a pores, the pitch ET must also need to pay attention to the vehicle, otherwise the vehicle can cause interference on travel and steering.
Learn to these, you can rest assured that the bold hub ~
