Wheels and Tyres: Key Components of Automobiles
In the automobile industry, wheels and tyres play a crucial role in determining vehicle performance. The specifications of these components can significantly impact the driving experience. For instance, the size of the wheel can affect acceleration and handling. A larger wheel generally provides better grip but may lead to a harsher ride.

The ET (offset) of a wheel indicates how far the mounting surface is from the centerline. For example, an ET of 35 mm means the mounting surface is 35 mm towards the front of the wheel. This parameter is vital for ensuring that the wheel fits properly within the vehicle’s wheel well. Incorrect ET can cause rubbing against suspension components or the body of the car.

Another critical measurement is PCD (Pitch Circle Diameter), which is the diameter of the circle formed by the centers of the wheel bolts. A typical PCD might be 5×114.3, meaning there are five bolt holes on a circle with a diameter of 114.3 mm. This specification is essential for compatibility with the hub assembly.
CB (Center Bore) is also an important factor. It is the diameter of the hole in the center of the wheel that fits onto the hub. A common CB size could be 73.1 mm. If the CB is too small, it won’t fit over the hub; if it’s too large, it may lead to vibrations while driving.
