The automobile rim plays a very important role in the automobile exterior decoration design, and its shape design affects the beauty of the automobile to a large extent.

In the process of making cars, rims are also in a variety of forms, keeping up with the world trend. Over the years, the design materials and design process of wheel rims are also changing constantly, and the diversity of their shapes also reflects the personalized design of different brands of automobiles.

Of course, in addition to the cool shape, wind resistance and corresponding regulatory requirements should be considered in the design process, to better express the designer's ideas.

For car lovers, rim design is also a key step to showing personalization. Therefore, the rim design, which integrates functions, materials, processes, structures, and colors, is unique. Now, let's enjoy the classic rim designs of major automobile manufacturers.

Lightweight is the trend in automobile design, of course, it is also the trend in rim design. In the future, with the maturity of 3D printing technology, lightweight and personalized design will become the mainstream design. The designer or the car owner only needs to draw the shape he wants on the drawing, which can be customized.

With the research and development of Airbus, the design of collapsible rims and tires will also become a major trend.

In the continuous development of automobile rims, whether German or American, or Japanese, more and more tension line designs have been added to the rim matching design, which makes the whole wheel more dynamic and makes the car more beautiful.

It should be noted that the rim is the fixed foundation of the tire, and the type and specification of the rim is an important technical basis for the selection and design of tires and valves, as well as an important factor affecting the service life of the tire.

How to choose the rim?

The following data are mainly involved here:

Diameter: the diameter of the rim is in inches, and it can be selected as long as it is the same as the tire diameter.

Width: rim width, i.e. J value, mainly refers to the distance between the flanges on both sides of the rim. If the J value is too large but the tire size is too small, it is likely to cause the vehicle to unseat when driving at low tire pressure.

Offset: This concept comes from German EinpressTiefe (ET), which translates as "pressed depth".

Pay special attention to this part of the data when selecting corresponding products. ET value determines whether the rim interferes with vehicle components.

Hole pitch: rim hole pitch, also called "PCD", in mm, refers to the diameter between the fixing bolts in the center of the hub.

Center hole: the center hole is the part used for a fixed connection with the vehicle, that is, the position of the hub center and the concentric circle of the hub.
