Run-flat tires have inner tubes, and their construction is basically similar to that of ordinary tires. The following is a related introduction to run-flat tires: 1. Introduction to run-flat inner tubes: Run-flat tires are technically called "puncture-proof tires." The sidewall of an inflated run-flat tire is the main part that supports the vehicle's weight, especially for tires with a larger aspect ratio (the ratio of tire height to width), where the sidewall is very "thick." 2. The difference between run-flat tires and ordinary tires: The sidewalls of run-flat tires are very thick, and the sidewall of an inflated tire is the main part that supports the vehicle's weight. 3. The structure of run-flat tires: Run-flat tires consist of an outer tire, a standard inner tube, a spare inner tube, a steel rim, a gas generator, a pressure sensor, and a control unit. Run-flat tires have special symbols following the specifications on the tire sidewall, which ordinary tires do not have.

Is it mandatory to install ETC?

It is not mandatory to install ETC. Vehicles without ETC can still use highways. According to the State Council's regulations, starting from 2020, vehicles without ETC will not enjoy toll discounts. In the future, only one manual lane will be retained at highway toll stations, and tolls can only be paid through manual lanes. Additionally, newly installed ETC devices cannot be used on highways immediately; they need to be activated first. During free holiday periods, highways can still be used. For users who have already installed ETC, passing through ETC lanes will not incur charges. ETC Billing Principle: There will be one or more ETC lanes on highways. Through microwave dedicated short-range communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, and using computer networking technology for backend settlement with banks, the purpose of paying highway tolls without stopping at toll stations is achieved. All this is based on the principle of passing first and deducting fees later. Benefits of Installing ETC: Time-saving: Eliminates the hassle of waiting in queues; Green and environmentally friendly: Green and low-carbon, vehicles pass through toll stations without stopping, reducing noise and exhaust emissions, thereby decreasing pollution; Reduced wear and tear: Saves costs, reduces the frequency of vehicle starts and brakes, lowers wear and fuel consumption, and users can also enjoy a 5% discount on tolls; Improved efficiency: Theoretically, ETC lanes can improve vehicle passing efficiency by 2-3 times, making traditional ETC updates faster and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council clearly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation smart cards in key city clusters will be basically achieved, and the proportion of vehicles using ETC will be significantly increased." It also explicitly set the goal in the "13th Five-Year" comprehensive transportation development indicators that "by 2020, the ETC usage rate for road passenger vehicles will reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and the ETC usage rate for passenger vehicles, the future will also promote the use of ETC for trucks and explore the deep integration of the ETC system with vehicle-to-vehicle communication, vehicle-road coordination, and other smart transportation development directions, providing comprehensive travel services for vehicle owners. This means more application scenarios will support ETC applications.

How to Make Halogen Lights Brighter Without Modifying the Headlights?

The brightness can be slightly improved compared to the original halogen bulbs, and a pair usually costs just over a hundred, making it a cost-effective and convenient option. Directly replacing halogen bulbs with xenon or LED bulbs can significantly improve brightness, but the lighting width, range, and distance remain unchanged. Increasing the voltage to over 23,000V creates a high-voltage breakdown of xenon gas, forming an arc between the two electrodes and producing light. However, the light tends to scatter and requires matching bi-xenon projectors to perfectly focus the beam. Upgrading to bi-xenon projectors generally costs anywhere from over a thousand to several thousand yuan.
