Tires should be replaced when the tread depth is less than 2.5mm. A tread depth standard greater than 3.5mm is considered good condition, while between 2.5mm and 3.5mm is normal. When it reaches the minimum limit of 1.6mm, replacement is mandatory. Key considerations for tire replacement include: 1. Selecting tires of the same specification; 2. Replacing the valve stem simultaneously; 3. Paying attention to installation direction and inflation; 4. Checking tire pressure; 5. Performing a four-wheel alignment after replacement. The functions of tires are: 1. Transmitting driving force, braking force, and steering force to enable vehicle operation; 2. Supporting vehicle load; 3. Reducing and absorbing vibrations and impacts during driving to prevent severe vibrations from damaging automotive components.

What do the letters and numbers on car engine oil mean?

Car engine oil letters and numbers indicate: The symbol W stands for Winter, which is the abbreviation of Winter. The smaller the number before W, the lower the viscosity at low temperatures and the better the low-temperature fluidity, making it suitable for lower minimum temperatures. The larger the number after W, the higher the viscosity, ensuring more stable protection under high-temperature conditions. When using engine oil, ensure that the oil grade is correct and that the oil is genuine. Using counterfeit or substandard oil can damage the engine.

What to Do If the Car USB Port is Broken?

The car USB port may be broken due to internal wire breakage or solder joint detachment, and it should be replaced at a 4S shop or an auto repair shop. Since USB drives are often plugged into the car USB port for extended periods during use, the vibration and shaking of the vehicle while driving can easily cause loosening. USB is a serial bus standard for connecting computer systems to external devices, as well as a technical specification for input/output interfaces. It is widely used in information and communication products such as personal computers and mobile devices, and has been extended to related fields like photographic equipment, digital TVs, and game consoles. If the USB car charger power does not match, it may result in no charging or insufficient charging. In such cases, it is necessary to confirm whether the charging current is compatible.
