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.

What documents are needed after buying a car?

After purchasing a car, you must obtain the following documents: a vehicle license, purchase invoice, insurance policy, motor vehicle registration certificate, purchase tax certificate, annual inspection label, compulsory traffic insurance label, and environmental protection label. New cars must pass an inspection at a vehicle testing facility before license plates can be issued. Precautions for new cars are as follows: 1. Tax payment: Tax payment is an essential step in car purchase. Most tax payment windows do not accept cash, so prepare a bank card in advance. Usually, the vehicle management office also has tax payment windows, so you can pay at the dedicated window there. 2. Choosing the model and configuration: The first step in buying a car is selecting the model and desired configuration. When determining the model, be sure to consider your budget. The principle of car selection is to first decide what type of car you want, such as a sedan or SUV, and then consider your sensitivity to certain parameters, such as fuel consumption, maintenance costs, space, noise level, and loading capacity.

How to Monitor the Lifespan of Built-in Tire Pressure?

Built-in tire pressure monitoring batteries typically last 2-3 years. Different brands of tire pressure monitors use different types of batteries, resulting in varying battery lifespans. Built-in tire pressure monitoring refers to sensors installed between the tire and the wheel rim, replacing the original valve stem. Therefore, professional installation at a tire shop is required, and wheel balancing must be performed. Advantages include: high precision in tire pressure measurement, theft and loss prevention, no need to remove sensors when inflating tires, and a one-time installation for long-term use. Tire pressure monitoring automatically checks tire pressure in real-time while driving, alerting drivers to leaks or low pressure to ensure safe driving. When tire pressure is too high, the contact area between the tire and the ground decreases, increasing the pressure on the tire and affecting traction. Additionally, when driving over bumps or uneven surfaces, insufficient space inside the tire to absorb shocks can compromise driving stability and passenger comfort, while also increasing stress on the suspension system, potentially leading to hazards. Moreover, the risk of tire blowouts in high temperatures may also rise accordingly.

Is it troublesome to register a car in a different location?

Registering a car in a different location is basically the same process as registering it locally. If the car owner needs to register the car in a different city, they will need a nationwide temporary license plate. If it's within the same city, a regular temporary license plate will suffice. The registration process is the same as for a locally purchased car: bring a copy of the owner's ID card, the original and a copy of the vehicle qualification certificate, the original tax payment slip, and fill out a tax declaration form. After paying the tax, you will receive a receipt and the original and duplicate copies of the tax payment certificate. The original is kept by the individual, while the duplicate is used for registration. Below is additional information on the required documents for registration in China: 1. China's regulations for new car registration stipulate that as long as the vehicle has the four basic documents—a formal invoice, qualification certificate, purchase tax (additional fee), and compulsory insurance (traffic compulsory insurance)—it can be registered. 2. Here is additional information on the materials the car owner needs to prepare: (1) Original and copy of the qualification certificate. (2) Original purchase invoice (three copies in total). (3) Owner's ID card. (4) Insurance policy.

What is the reason for no power to the compressor in a 2005 Passat?

The air conditioning high and low pressure switch may be damaged, or the relay may have a problem. The following are the specific functions of the air compressor: 1. Compressed gas as power. After being compressed, air can be used as power for machinery and pneumatic tools, as well as for control instruments and automation devices. 2. Compressed gas is used for refrigeration and gas separation. Gas is compressed, cooled, and expanded to liquefy, which is used for artificial refrigeration, commonly known as an ice maker or ice machine. If the liquefied gas is a mixture, the components can be separated in a separation device to obtain various gases with qualified purity. For example, the separation of petroleum cracking gas involves compression first, and then the components are separated at different temperatures. 3. Compressed gas is used for synthesis and polymerization. In the chemical industry, certain gases are pressurized by compressors to facilitate synthesis and polymerization. For example, nitrogen and hydrogen synthesize ammonia, hydrogen and carbon dioxide synthesize methanol, and carbon dioxide and ammonia synthesize urea. 4. Gas transportation. Compressors are also used for pipeline transportation and bottling of gases. For example, the transportation of remote coal gas and natural gas, and the bottling of chlorine and carbon dioxide.

What Needs to Be Checked Before Driving on the Highway?

When driving at high speeds, the key areas to inspect are the engine, brakes, and chassis components. Taking the engine as an example, it is essential to check the engine cooling system before high-speed driving. If there is an issue with the coolant, such as insufficient levels, it can easily lead to engine overheating and boiling at high speeds. Additionally, the windshield washer fluid should also be checked. During high-speed driving, the windshield tends to get dirty quickly. If the glass becomes dirty and there is no washer fluid, visibility can be severely impaired. For the brakes, it is necessary to check whether the brake fluid is contaminated and if the brake pads are worn. Worn brake pads should be replaced promptly, as brakes are a critical safety component of the vehicle and directly impact driving safety. Lastly, tire pressure should be checked before high-speed driving. The tire pressure must be within the standard range. At high speeds, tire pressure increases due to the heat generated by tire movement. Incorrect tire pressure can lead to various issues. Overinflation increases the risk of a blowout, while underinflation can reduce vehicle performance and even increase fuel consumption.
