What Does the Tire Model Number Mean?

Tire model numbers represent the tire's width, aspect ratio, type, and applicable size. For example, a tire model number like 205/60R16 can be interpreted as follows: The first number 205 indicates the tire width is 205 millimeters. The number 60 denotes the tire's aspect ratio is 60%, meaning the sidewall height is 60% of the tire's width. The letter R stands for radial tire, and 16 signifies the rim diameter is 16 inches. In addition to the model number, tires also display the following common specifications: Carcass ply material: Indicated by Chinese pinyin abbreviations, such as M for cotton cord, R for rayon cord, N for nylon cord, G for steel cord, and ZG for steel radial cord. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under defined conditions. Letters from A to Z represent certified speed ratings ranging from 4.8 km/h to 300 km/h. Common speed ratings include: Q: 160 km/h; H: 210 km/h; V: 240 km/h; W: 270 km/h; Y: 300 km/h. Rim specification: Shows the compatible rim size for the tire, facilitating practical use, such as "Standard Rim 5.00F".

What is the green book of a car called?

The green book is the registration certificate, which is issued to the car owner on the spot by the staff of the vehicle management office at the inspection site when a new car is registered. More relevant information is as follows: 1. Introduction: The so-called big green book is the 'Motor Vehicle Registration Certificate', which is equivalent to a person's household registration booklet. It records the registration date and the date of manufacture, and is kept by the vehicle owner. It is generally not used on a daily basis and is not carried with the vehicle. However, it must be used when transferring the ownership of the vehicle. If the car is mortgaged for a loan, the lending company will usually also hold the big green book. Losing the big green book means that we only have the right to use the vehicle but not the right to sell it. 2. Prerequisite: Only when the car is purchased in full can the green book be obtained. If the car is purchased with a loan, the green book must be mortgaged to the loan bank or company. After the customer repays the loan, the big green book must be taken to the vehicle management office to release the mortgage, otherwise the ownership of the car will belong to the loan company.

What is the difference between antifreeze and water?

The difference between antifreeze and water lies in the fact that automotive antifreeze has a higher boiling point and lower freezing point than water. Antifreeze can reach a boiling point of 106°C and a freezing point below -45°C, offering better cooling performance and superior freeze protection compared to water. Additionally, antifreeze contains various special additives that provide anti-corrosion, anti-scaling, and anti-rust properties. Methods for selecting antifreeze: The basic indicators for antifreeze are its freezing and boiling points. The market offers antifreeze with freezing points of -15°C, -25°C, -30°C, -40°C, etc. Generally, it is advisable to choose an antifreeze with a freezing point at least 10°C lower than the lowest temperature in your region. Antifreeze replacement intervals: For vehicles that operate for extended periods, such as taxis, high-quality antifreeze should typically be replaced annually. Vehicles with shorter operating times can have their antifreeze replaced every two years or every 30,000 kilometers. To prevent excessive foam formation, which can reduce the heat exchange efficiency between the antifreeze and engine components, ensure the product is within its validity period when adding it. Long-life antifreeze can remain effective for up to three years. If suspended particles, sediment, or signs of deterioration or discoloration are observed in the antifreeze, it should be replaced promptly, and the system should be cleaned.

What does the AC switch on the air conditioner mean?

The car AC switch is the cooling switch, commonly referred to as turning on the cold air. The AC switch controls the compressor, which is one of the main components of the car's air conditioning refrigeration system, responsible for compressing and transporting refrigerant vapor. Proper use of the AC switch: 1. Cold seasons: In cold seasons, it is necessary to quickly raise the temperature inside the car. When the car starts, the engine begins to warm up. Wait until the engine temperature gauge needle points to the middle position, then turn on the warm air conditioning, and at the same time set the air circulation to external circulation to allow the cold air inside the car to be expelled or wait for 2 to 3 minutes before setting the air circulation to internal circulation. 2. Rainy or snowy weather: In rainy or snowy weather, when there is a large temperature difference between the inside and outside of the car, the front windshield is very prone to fogging. At this time, simply adjust the warm air outlet direction to the position that blows on the front windshield, and the fog can be removed in a few minutes.

What to Do When the Central Locking System Frequently Jumps?

For the reasons and solutions to the frequent jumping of the central locking system, the details are as follows: 1. Damaged brake light power line: When the central locking system receives the correct code signal, the control wave receiving circuit is triggered to increase the receiving time. If the input code signal does not match, the receiving circuit will not be triggered. Solution: Check the integrity of the power line promptly and replace it in time. 2. Incorrect power connection of the central locking system: If more than 10 code signals do not match, the lock will assume that the power connection of the central locking system is incorrect and will stop receiving any signals, including the correct code signals. Solution: In this case, the owner can mechanically insert the key into the door lock hole to open the door. 3. System not closed in time: Signal reception recovery, if the door is not opened within 30 seconds after unlocking it with the remote mechanism, the door will automatically lock again. Solution: Start the car with the key and turn the main switch of the remote door lock system off and then on again.
