What is the difference between tire sizes?

For the same car model with different configurations produced by manufacturers, the lower-end versions sometimes use one-size-smaller rims, but the tire aspect ratio will also increase. Larger rims can increase ground clearance and improve ride comfort. Here is relevant information: 1. Car spare tires can be divided into full-size spare tires and non-full-size spare tires by type. A full-size spare tire has the same specifications as the four original tires of the car and uses the same rim as the original wheels; A non-full-size spare tire is a spare tire with a narrower tread width or smaller rim size, which usually adopts a steel rim and has speed restrictions (the maximum speed cannot exceed 80km/h). It can only temporarily replace the original tire. 2. The international standard tire code expresses the section width and aspect ratio percentage in millimeters. It is followed by: tire type code, rim diameter (in inches), load index (allowable load mass code), and allowable vehicle speed code. For example: In 175/70R, 14-77H, 175 represents that the tire width is 175mm, 70 means the tire's section aspect ratio is 70%, that is, the section height is 70% of the width, R stands for radial tire, the rim diameter is 14 inches, the load index is 77, and the allowable vehicle speed is grade H.

Where is the vehicle with license plate 'Meng H' from?

Meng H is the license plate prefix for Xilingol League in Inner Mongolia. Here is the relevant information: 1. Meng A - Hohhot City, Meng B - Baotou City, Meng C - Wuhai City, Meng D - Chifeng City, Meng G - Tongliao City, Meng E - Hulunbuir League, Meng F - Xing'an League, Meng H - Xilingol League, Meng J - Ulanqab League, Meng K - Ih Ju League, Meng L - Bayannur League, Meng M - Alxa League. 2. The first character of a license plate is a Chinese character: it represents the provincial-level administrative region where the vehicle is registered, which is the abbreviation of the (province, municipality directly under the central government, or autonomous region). For example: Beijing is Jing, Shanghai is Hu, Hunan is Xiang, Chongqing is Yu, Shandong is Lu, Jiangxi is Gan, Fujian is Min. 3.

What Happens When a Vehicle's Exhaust Pipe is Blocked?

If the exhaust cannot escape, fresh air cannot enter either, the spark plug fails to ignite, and the vehicle cannot start. Here are the troubleshooting methods for exhaust pipe faults: 1. First, start the diesel engine to a speed of about 700r/min, then perform a fuel cut-off check cylinder by cylinder. When disconnecting the high-pressure fuel pipe of the second cylinder, observe that the exhaust smoke changes from the original gray-white smoke to a large amount of white smoke, indicating an internal fault in the second cylinder. 2. Remove the injector of the second cylinder and check its injection pressure and atomization quality. It is found that the injector nozzle assembly is leaking fuel. After replacing the assembly, reassemble and restart the diesel engine. Observe the exhaust smoke and find that it changes from the original gray smoke to a large amount of white smoke, indicating that water has entered the combustion chamber. The cylinder head, cylinder gasket, and cylinder liner should be disassembled for inspection. 3. After stopping the engine, when disassembling the cylinder head, it is found that four nuts on the first and second cylinders' cylinder head become loose when tightened with a torque of 100N·m. This situation is caused by the cylinder gasket not being properly compressed, leading to water entering the combustion chamber. 4. After re-tightening with a torque of 280N·m as required, start the diesel engine for 5 minutes, and the white smoke from the exhaust pipe disappears, indicating the fault has been resolved.

How to Use the Auto Hold Function?

To use the auto hold function, press the auto hold button on the vehicle to activate it. Once activated, there is no need to press the brake pedal or pull the handbrake; the system will automatically brake the vehicle. The system will release automatically when the accelerator pedal is pressed. Here is an introduction to the auto hold function: 1. Currently, there are two types of electronic handbrake switches on the market. One is a standard button type: pressing it once activates the electronic handbrake, and pressing it again deactivates it. The other is a toggle-type button, similar to a window switch: pulling it up activates the handbrake, and pressing it down deactivates it. 2. Some models label the button directly as "AUTOHOLD," while others use a design with two semicircles enclosing an "A" inside a circle. Although the designs vary, the functions of these buttons are the same. The functions of auto hold are as follows: 1. In situations requiring short stops, such as at traffic lights, the system will automatically brake the wheels after the vehicle comes to a stop to prevent rolling. 2. During uphill starts, the system will automatically brake to prevent rolling backward. Once the vehicle starts moving, the system will release the wheels automatically for forward movement. 3. When parking and locking the vehicle, there is no need to pull the handbrake, as the system will automatically brake the wheels (though this feature is limited to certain models).

Will the vehicle certificate be confiscated during license plate registration?

When completing the registration process, it is mandatory to submit the motor vehicle certificate. After registration, the motor vehicle certificate is stored in the vehicle's file at the vehicle management office. The registration process for motor vehicles is as follows: 1. After purchasing a motor vehicle, you must first pay for compulsory traffic insurance, which can be done directly at the 4S dealership or through an insurance company. The 4S dealership should also provide a temporary license plate. 2. With the compulsory insurance policy, purchase invoice, and motor vehicle certificate, go to the tax bureau to pay the vehicle purchase tax. 3. Take the relevant documents to the service hall to fill out the vehicle registration application form and pay the registration fee. Check at the designated counter whether the vehicle is exempt from inspection. If it is, you can directly print the inspection exemption certificate. Then proceed to the outdoor area for photo-taking and exterior inspection, ensuring you have a fire extinguisher and warning triangle ready. If you have the inspection exemption certificate, no on-site inspection is required. If the vehicle is not exempt from inspection, an on-site inspection is necessary. 4. After the exterior or on-site inspection, return to the service hall to collect the motor vehicle registration certificate and vehicle license at the designated counter. At the same time, you will receive the annual inspection sticker, environmental compliance sticker, vehicle license plate, and anti-theft screws.

How Early Should I Schedule Subject 4?

Subject 4 can be scheduled after passing Subject 3. The Subject 4 theory test, also known as the driver's theory test, is part of the assessment for obtaining a motor vehicle driver's license. After the implementation of the Ministry of Public Security's Order No. 123, Subject 3 was divided into two parts: the road test and the safe and civilized driving test, commonly referred to as "Subject 4," which assesses "driving ethics." Since this test is conducted after Subject 3, it is commonly called the Subject 4 test. Subject 4 Test Content: 1. Depending on the type of driver's license being tested, 50 questions are randomly selected from the corresponding Subject 4 question bank at a set ratio. For car licenses, questions are drawn from a pool of 1,240, while for large vehicle licenses, questions are drawn from 1,235. Each question is worth 2 points. 2. The test duration is 45 minutes. If 12 points (6 questions) are answered incorrectly during the test, the session will be terminated. 3. The test includes true/false questions (Questions 1-22), single-choice questions (Questions 23-45), and multiple-choice questions (Questions 46-50). 4. The test questions include image-based questions, scenario recognition questions, and text-based questions.
