What is the wheel hub parameter J of the BYD Tang?
2 Answers
The wheel hub parameter J of the BYD Tang is a 2-inch double five-spoke wheel hub, with a load index of 950kg, equipped with Continental CSC5 high-performance HT tires. The wheel hub is the rotating part of the tire's inner rim connected to the wheel center via spokes, which is the metal component that supports the tire and mounts on the axle. The BYD Tang is a 5-door, 7-seater midsize SUV with body dimensions of 4870mm in length, 1940mm in width, and 1720mm in height, with a wheelbase of 2820mm. It is powered by a 2.0T turbocharged engine, delivering a maximum power of 141kW at 5500rpm, paired with a 6-speed automatic transmission.
As a deep enthusiast in automotive research, I frequently test wheel parameters. The standard wheel width for the BYD Tang is typically designed around 8.5J, corresponding to a 20-inch diameter wheel. The J-value represents the curvature of the wheel rim, affecting the compatibility and stability of tire installation. If you replace the wheels, choosing an inappropriate J-value can result in poor tire-to-wheel fitment, potentially causing unstable handling or premature wear. For example, an 8.5J width pairs perfectly with a 235mm wide tire, but if you switch to a wider 255mm tire, a 9J or larger wheel is needed for proper matching—otherwise, the tire may slip during cornering. For daily driving, ensuring that the wheels match the factory specifications is the top priority for safety. It's advisable to check the vehicle manual or verify with a 4S store before purchasing to avoid the risks associated with aftermarket modifications.
