What are the wheel hub specifications for the new Bluebird?
1 Answers
The 2021 Bluebird comes standard with aluminum alloy wheels across all models. The center bore diameter is 66.1 millimeters, with 15-inch wheels and 4-lug bolts. Wheel size: Wheel size essentially refers to the diameter of the wheel, typically measured in inches. For example, 15-inch or 16-inch wheels indicate the wheel diameter. The width of the wheel is commonly referred to as the J-value. The wheel width directly affects tire selection. For tires of the same size, different J-values will require different tire aspect ratios and widths. Pitch Circle Diameter: The professional term for PCD is Pitch Circle Diameter, which refers to the diameter of the circle formed by the centers of the mounting bolts. For example, 5x112 means the wheel's PCD is 112mm with 4 bolt holes.
