Find the tire manufacturer and have them conduct the certification. If it is not a quality issue, request the manufacturer to issue a legally valid quality certification document; with this certification document, you can then go to Zhongke Testing, whose issued certificates are authoritative; third-party agencies that certify tire quality. The current state of testing in China: Domestic products are tested by national testing agencies, such as the Quality Supervision Bureau and the Disease Control Center, while exports are mainly handled by foreign testing agencies. Domestic third-party testing agencies are struggling to survive in the gaps. Tire size classification: A full-size spare tire has the exact same specifications as the other four tires on the vehicle and can replace any temporarily or permanently unusable tire. A non-full-size spare tire has a slightly smaller diameter and width than the other four tires, so it can only be used as a temporary substitute and must be placed on a non-drive wheel, with a maximum speed not exceeding 80km/h.

Why are the production dates of the new car's windows different?

It is normal for the production dates of the new car's windows to be different, as long as the production date of the windows is earlier than the manufacturing date of the entire vehicle. The car's windows are purchased externally and then assembled onto the vehicle. During installation, they are randomly installed according to the production batch of the windows, so different dates are normal. Here's how to interpret the production date of car windows: 1. Currently, the most common method for indicating the production date of windows on the market is a combination of numbers and dots, where the numbers represent the year and the dots represent the month; 2. The dots can be placed either before or after the numbers. Dots before the numbers indicate the first half of the year, and the month can be calculated by subtracting the number of dots before the numbers from 7; 3. Dots after the numbers indicate the second half of the year, and the month can be calculated by subtracting the number of dots after the numbers from 13.

What to Do When Vehicle Air Conditioning Repair Causes One-Button Start Failure?

Vehicle air conditioning repair causing one-button start failure can be resolved by analyzing and inspecting two major components: the circulation system parts and the electrical control system. If the air conditioning system is not cooling, check the control system first. If the control system is functioning properly, proceed to inspect the air conditioning circuit, and finally diagnose the cooling system faults. Car air conditioning refers to the air conditioning device installed in vehicles, which can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety. The method for maintaining car air conditioning is: a few minutes before reaching the destination, the owner should turn off the air conditioning and switch to natural air to allow the temperature inside the air conditioning pipes to rise, eliminating the temperature difference with the outside environment, thereby maintaining relative dryness in the air conditioning system and preventing mold growth.

How to Deal with Musty Smell in Car Air Conditioning?

Here are some methods to address the musty smell in car air conditioning: 1. Before turning off the engine, turn off the air conditioning compressor in advance and switch the mode to external circulation, allowing hot air to dry the moisture in the air conditioning ducts. This prevents the air conditioning from becoming damp and breeding bacteria, which can cause odors. 2. First, open all windows and doors, then turn on the fan to accelerate air circulation. After a few minutes, close the windows and doors and turn on the air conditioning. This releases toxic substances and helps cool the car quickly. 3. Choose to direct the airflow diagonally upward. Utilize the principle that hot air rises and cold air sinks, allowing cold air to cool the car from top to bottom. 4. Switch between internal and external circulation. If the vehicle is in a congested urban area, to prevent exhaust fumes and other pollutants from entering the car, the driver can use the air conditioning's internal circulation function.
