When using a tire pressure gauge, press the air nozzle connector firmly onto the tire valve stem to depress the valve core. The value displayed on the gauge is the tire pressure. During measurement, ensure the pressure gauge is properly aligned with the valve stem to prevent air leakage, as this can lead to inaccurate readings. Standard tire pressure values: According to the international GBT2978-2008 standard, the recommended tire pressure for standard tires is 2.4-2.5 bar. When to adjust tire pressure: Generally, it is recommended to check tire pressure at least once a month and adjust it seasonally. The ideal times for adjustment are November and May. In November, as winter approaches, tire pressure typically decreases and may require slight adjustment. In May, as temperatures rise, check if the pressure is normal. Notably, if the tire pressure is within the standard range, do not intentionally reduce it. If the tires are not underinflated, monthly adjustments are unnecessary.

How often should the belt on a BMW 530LE be replaced?

The generator belt on a BMW 530LE should be replaced at 80,000 kilometers. When replacing the belt, it is essential to choose genuine OEM products and have it replaced by a professional. Below is relevant information about the timing belt: Function of the timing belt: The timing belt is crucial for the proper operation of the engine. If the timing belt fails, the valves and ignition system will stop working, and in severe cases, the cylinder head may also be damaged. As the engine operating time increases, the timing belt and its related components, such as the timing belt tensioner pulley, timing belt tensioner, and water pump, will experience wear or aging. Therefore, these components should be thoroughly inspected for any issues each time the belt is replaced. Precautions for using the timing belt: During use, regularly inspect the condition of the timing belt. If cracks are visible on the surface of the timing belt, pay attention to whether the belt has aged. If there are unusual noises while driving, check whether the timing belt is installed correctly.
