How to Identify the Tire Production Date?

Tire production dates are indicated by a four-digit number, which is marked on the sidewall of the tire. The first two digits represent the production week, and the last two digits represent the year. Here are the methods to identify the tire production date: 1. Similar to the vehicle production date, the tire production date is actually marked on the outer side of the tire. You don't need to flip the tire; it's on the outside, on one side of the tire wall. There is a set of numbers, and the last four digits of this marking provide information about the production date. It consists of four digits "AABB." The first two digits "AA" indicate the week of the year, and the last two digits "BB" indicate the year. 2. Generally, the 11-digit number and letters immediately following the "DOT" marking on the tire sidewall represent the tire's identification number or serial number. The last four digits of the serial number indicate the tire's production date.

What is the China VI Vehicle Emission Standard?

China VI vehicle emission standard includes: 1. Carbon monoxide content is 500 milligrams per kilometer; 2. Nitrogen oxides content is 35 milligrams; 3. Particulate matter content is 3 milligrams; 4. Non-methane hydrocarbons content is 35 milligrams. Emission standards refer to the levels of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, and soot emitted from vehicle exhaust. The vehicle emission standard is established to prevent pollution from the exhaust of compression-ignition and gas-fueled spark-ignition engine vehicles, protect the ecological environment, and safeguard human health. Vehicle emission standards are categorized into: 1. Vehicles with a total mass less than or equal to 3.5 tons equipped with spark-ignition or compression-ignition engines; 2. Vehicles with a total mass greater than 3.5 tons equipped with spark-ignition engines; 3. Vehicles with a total mass greater than 3.5 tons equipped with compression-ignition engines.

What is the validity period of a newly issued motor vehicle driver's license?

The validity period of a newly issued motor vehicle driver's license is six years. The specific details are as follows: If the validity period expires within one year: The driver should apply for a renewal at the vehicle management office within 90 days (three months) before the license expires. The license can still be renewed normally within one year after expiration. If the validity period expires between one and three years: The driver's license will be revoked, and the holder must retake the subject one exam to obtain a new license. If the license expires for more than three years, it will be invalidated directly. The first renewal period for a driver's license is six years. If no demerit points reach 12 in any cycle during these six years, the license will be renewed with a validity period of 10 years. If there is a case where demerit points reach 12 in any cycle, the license will still be renewed with a validity period of six years. When the 10-year license expires, if no demerit points reach 12 in any cycle, a long-term valid driver's license can be issued.

What is the normal range for instantaneous fuel consumption?

Modern electronic fuel injection engines can cut off fuel supply during coasting, so the minimum instantaneous fuel consumption is 0. The maximum is essentially the upper limit set by the vehicle model—some cars have a limit of 49.9, while others may go up to 99.9. Below is relevant information: Introduction: Instantaneous fuel consumption indicates the fuel usage at a specific moment. The display unit is "liters per 100 kilometers (L/100Km)" when the vehicle is in motion, and "liters per hour (L/H)" when the engine is running but the vehicle is stationary. Significance of instantaneous fuel consumption: Monitoring instantaneous fuel consumption is crucial for understanding the engine's fuel usage under different conditions. For example, it helps determine fuel consumption when the vehicle is stationary with the engine idling. It also allows you to assess the fuel consumption per 100 kilometers at various speeds (aerodynamic drag, which significantly impacts fuel consumption, is proportional to the square of the speed), helping identify the vehicle's most fuel-efficient speed. For vehicles with computer-controlled fuel injection, instantaneous fuel consumption can show "0" during gear coasting (when the fuel injectors stop supplying fuel).

How many kilometers do car tires need to be replaced?

Tire replacement intervals are generally around 2-3 years or after driving 60,000-100,000 kilometers. Of course, the service life specified by different brands may vary, as requirements for tires differ slightly. However, relying solely on a numerical value to determine replacement time is insufficient—the actual condition of the tire should ultimately decide. There are many influencing factors, and if any of the following situations occur, there may be potential safety hazards, necessitating timely replacement of a new tire. Below are relevant details: Wear level: The most direct method is to observe the tire's wear level. Almost every tire has a wear indicator. Generally, the wear indicator height for passenger car tires is 1.6 millimeters (this is also the legally mandated minimum groove depth), while for load-bearing tires, it is 2.4 millimeters. If the wear indicator aligns with the tread, it indicates significant wear and the tire should be replaced promptly. Tire aging: Of course, merely checking the wear level isn't enough, as some car owners rarely use their vehicles and thus experience minimal tire wear. Over time, aging phenomena (such as tread cracks and hardened rubber) will inevitably occur. Especially if the tire has exceeded its replacement cycle, it's crucial to regularly inspect its condition. If the aging is severe, immediate replacement is necessary.

What does an agreement car mean?

An agreement car refers to a vehicle where the license plate is registered under someone else's name, typically the agreement holder, while the vehicle ownership is registered under the other party involved in the agreement. The term 'agreement car' is not a standardized expression and generally indicates that the ownership of the vehicle is determined through an agreement between the two parties. Below is relevant information: Article 18, Paragraph 1 of the 'Motor Vehicle Regulations' stipulates: 'When the ownership of a registered motor vehicle is transferred, the current owner shall apply for a transfer registration with the local vehicle management office within 30 days from the date of delivery.' According to this regulation, the current owner must complete the transfer registration within 30 days of ownership transfer. However, this is an administrative requirement rather than a validity requirement, meaning failure to complete the transfer registration does not affect the validity of the motor vehicle sales contract. Article 50 of the 'Tort Liability Law' states: 'If the parties have transferred the motor vehicle through sale or other means and delivered it but have not completed the ownership transfer registration, and a traffic accident occurs for which the motor vehicle is at fault, the insurance company shall compensate within the limits of the compulsory motor vehicle insurance liability. Any insufficient amount shall be borne by the transferee.' This provision confirms that the motor vehicle sales contract remains valid even if the transfer registration is not completed.
