Because the speedometer reading of the car is based on the wheel speed measurement, wheel diameter is too large to cause the speedometer reading is small, imperceptibly, you are speeding. Excessive wheel diameters also rub against the wheel arch and wing plate. Therefore, it is better to upgrade the hub to be 1 inch larger than the original factory, no more than 2 inches at most, and also to match the thin tire to ensure the size of the whole wheel is the same as before the upgrade.
2. Pitch circle diameter: for example, the hub with a pitch circle diameter of 5x120mm represents that it has 5 positioning bolts, and the circular diameter formed by them is 120mm. This value should also comply with the original factory.
3, center hole size: refers to the hub center hole size. Although hubs with different factory values can be installed with a shifter, this is not recommended for safety reasons.
