Precautions for wheel hub replacement
2021-03-01
In the concept of automobile manufacturers, the lower the cost, the better. The wheel hub has become a key object of cost reduction. As long as the size is just right, the rigidity reaches the standard, the original wheel hub has a single structure and a common model for production. Although the quality will not be a problem, it does not consider the individual needs of consumers. The wheels of some low-end cars are even so ugly that they "cannot bear to look straight." Therefore, the wheel hub has become an excellent place for car owners to show their personality in addition to the body stickers. Aotai wheels have a stylish appearance. However, there are many professional parameters involved in the replacement of the wheel hub, so it is best to do your homework before the replacement, so as not to bring hidden dangers to safety.
1. Central aperture (CB)

Refers to the size of the center hole of the wheel hub. Although it can be installed with a positioner, it is not recommended due to safety issues.
2. Pitch circle diameter (PCD)
For example, a hub with a pitch circle diameter of 4*100mm means that it has 4 positioning bolts, and the circle formed by them has a diameter of 100mm. This value should also be consistent with the original manufacturer.
3. Offset (OFFSET)
Abbreviated as ET value, this value is positive, indicating that the fixed surface of the wheel hub is outside the center plane, otherwise it is inside the center plane. The offset value of a car is generally a positive value. This value has a significant impact on the stability of the car and the tracking of corners. The original factory will determine it, and it cannot be changed unless it is required.
4. Diameter and width

The diameter determines the size of the rim. Since the speedometer reading of the car is measured according to the wheel speed, the wheel diameter is too large and the speedometer reading is too small. Unknowingly, you will be speeding. A wheel diameter that is too large will also scratch the wheel arches and fenders. Therefore, it is better to upgrade the wheel hub to be 1 inch larger than the original factory, no more than 2 inches at most, and to be equipped with thin tires to ensure that the size of the entire wheel is the same as before the upgrade. The width affects which tires are used after the upgrade. A tire that is too wide will reduce the starting speed and consume more fuel. Common values correspond to: 185mm wide tires correspond to 5-inch wide wheels; 195mm corresponds to 6 inches; 205mm corresponds to 6.5 inches; 215 corresponds to 7 inches. Aotai Wheels has everything.
