Tire pressure markings can be found on the sidewall of the tire. These markings indicate the maximum allowable pressure, not the recommended pressure. For example, a common marking might be '340 kPa,' which translates to 3.4 bar. According to national standards, tire sidewalls must display the production number, manufacturer's trademark, size specifications, load rating, maximum load and corresponding pressure, ply composition code (in Chinese Pinyin), installation requirements, and directional indicators. Strictly speaking, tire pressure refers to the air pressure inside the tire—essentially the 'blood pressure' of a car. The level of tire pressure plays a crucial role in a vehicle's performance and power.

Are There Any China V Motorcycles?

Not yet. China IV motorcycles have just been launched, and they are not yet widespread. China V will have to wait for several more years. China V will be implemented in a few years: As environmental standards become increasingly higher and stricter, motorcycles will definitely adopt the China V standard in the future. However, at present, the China IV standard has only just begun to be fully implemented. The China V standard will likely take at least a few more years before it is implemented, and there is no specific date yet. China V standard is equivalent to the Euro V standard in the EU: The EU has been implementing this standard since 2009, which imposes stricter limits on pollutants such as nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter from motor vehicles. Each upgrade in standards reduces vehicle pollution by 30% to 50%. As of January 2013, the China V standard was still in the public consultation phase. Research results show that upgrading the quality of automotive gasoline and diesel contributes significantly to emission reductions. Replacing China IV gasoline and diesel with China V will achieve at least a 10% and 7% reduction in nitrogen oxide emissions, respectively.

Will not using turn signals be captured by traffic cameras?

Not using turn signals will not be captured by traffic cameras. However, if seen by traffic police, they have the authority to issue penalties. During driver's license tests, failing to use turn signals will result in point deductions. According to Article 51, Item 3 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China": When motor vehicles pass through intersections controlled by traffic signals, they should follow the corresponding regulations: when turning left, turn from the left side of the intersection center point. Turn signals should be activated when turning, and low beams should be used when driving at night. Below is supplementary information on China's relevant legal regulations regarding turn signals: 1. When turning left, changing lanes to the left, preparing to overtake, leaving a parking spot, or making a U-turn, the left turn signal should be activated in advance. 2. When turning right, changing lanes to the right, returning to the original lane after overtaking, or parking by the roadside, the right turn signal should be activated in advance. 3. Failure to use lights as required may result in a fine and a 1-point deduction on the driver's license. 4. Article 90 of the "Road Traffic Safety Law of the People's Republic of China": Motor vehicle drivers who violate road traffic safety laws and regulations regarding road traffic rules will be given a warning or fined.

Is Audi's On-Demand Four-Wheel Drive Useful?

Audi's on-demand four-wheel drive is naturally useful, offering excellent off-road capability and strong handling. Here are the relevant details: 1. Full-Time Four-Wheel Drive: When full-time four-wheel drive was introduced, it was highly sought after by consumers. It provides powerful handling and ease of driving. Its superior off-road performance has won the hearts of many off-road enthusiasts. However, there is one drawback: Audi's full-time four-wheel drive is very fuel-consuming. Therefore, Audi introduced the on-demand four-wheel drive, an intelligent four-wheel drive mode applied to the Q5L, making it a major selling point and highlight of the Q5L. 2. The Difference Between On-Demand and Full-Time Four-Wheel Drive: The difference between on-demand and full-time four-wheel drive is that when driving on city roads, it operates as a two-wheel drive vehicle. However, on rugged mountain roads or muddy paths, it switches to four-wheel drive, ensuring safe travel. The introduction of on-demand four-wheel drive not only reduces the vehicle's weight but also enhances fuel efficiency and environmental friendliness while maintaining performance.

What Causes the Rattling Noise in Tesla on Bumpy Roads?

Tesla rattling noise on bumpy roads can be attributed to the following reasons: 1. Gaps Between Components: There may be gaps, misalignments, or shifts between leather, plastic, and wiring components, especially after prolonged exposure to sunlight. This can easily cause the car to produce rattling noises when driving on bumpy roads due to loose parts being squeezed. Generally, identifying the source of the noise and using materials like paper towels or rubber as spacers to block the gaps can help. 2. Collision Between the Car Audio Amplifier and Vehicle Components: This issue can usually be resolved by tightening the screws to secure the amplifier, CD player, and other components in place. 3. Collision Between the Sunroof Glass and Sunroof Frame: Prolonged exposure to sunlight can cause the sunroof rubber seal to soften, deform, and then harden, leading to gaps or misalignment. Additionally, if the sunroof sliding rails have not been maintained or lubricated for a long time, rattling noises are more likely to occur while driving.

The Only Method for Motorcycle License Plate Transfer?

License plate numbers cannot be transferred. Additional information: 1. License plates are not allowed to be bought or sold. After transferring or scrapping a vehicle, only the owner can apply to the vehicle management office to retain the license plate. Unused original license plate numbers will automatically be stored in the vehicle management office's motor license plate database and will not be reissued. 2. Many vehicle owners mistakenly believe that license plates are their private property and can be used indefinitely once obtained. License plates can only be retained and used by the original owner (individual or organization) and cannot be transferred to others. Original license plates can only be retained when the vehicle is transferred to another person or scrapped. If the owner relocates the vehicle to another region, even if the vehicle remains under their name, the original license plate cannot be retained. 3. If the owner wishes to retain the license plate, in principle, there is no need to inform the vehicle management office in advance. The system defaults to retaining the license plate for six months. Within this period, the owner only needs to inform the staff at the vehicle management office when registering the vehicle that they wish to use the original license plate under their name.
