Should I Replace the Tire if There Are Cracks on the Outside?

Whether to replace a tire with cracks on the outside depends on different situations: 1. If the cracks appear on the sidewall, replacement is necessary to avoid tire blowouts; 2. If the cracks are too long or deep, reaching the standard tread depth of 1.6 millimeters, replacement is required. The reasons for cracks on the outside of the tire are: 1. Natural aging of the tire; 2. The tire has been impacted. Precautions for using car tires include: 1. When inflating the tire, reduce the tire temperature to normal levels to avoid affecting pressure judgment; 2. Inflate to around 2.5 bar; 3. Regularly check the wear level of the car tires; 4. Avoid exposing the tires to high temperatures.

What is the replacement interval for clutch plates?

The replacement interval for clutch plates is approximately 100,000 kilometers. They are located between the engine and the transmission. The working principle of clutch plates is: the transmission of power is achieved through axial compression and release. The greater the axial pressure, the greater the friction generated, resulting in smoother and more stable operation of the extruder without slipping, jamming, or self-disengagement. Under normal operating conditions, the machine runs smoothly and quietly. Precautions for using clutch plates include: 1. If the clutch plate clearance adjustment is improper, check whether the surfaces of the intermediate pressure plate and the thrust plate are flat; 2. During assembly, carefully inspect the flatness of all components, and observe whether they are concentric during trial operation to avoid wear on the intermediate pressure plate and internal gear ring.

What are the effects of low tire pressure?

The effects of low tire pressure include: 1. Increased contact area between the tire and the ground; 2. Heavier steering wheel, affecting driving; 3. Tires are prone to overheating, increasing the risk of blowouts; 4. Expansion of the tire body, leading to cracks on the inner and outer sides; 5. Accelerated rubber aging and faster tire wear. The reasons for low tire pressure are: 1. Leaky valve stem; 2. Reduced tire sealing performance; 3. Long-term overloading of the vehicle; 4. Uneven tire force distribution. Solutions for low tire pressure include: 1. Inspect the cause of air leakage and repair or replace the tire; 2. Replace the wheel hub, adjust driving habits to ensure even tire force distribution.

What is the function of the set button in a sedan?

The functions of the set button in a sedan are: 1. To decelerate after setting the cruise control; 2. To temporarily cancel the cruise control. The role of the set button is: To automatically maintain the vehicle speed as required by the driver without stepping on the accelerator pedal, allowing the vehicle to travel at a fixed speed. When the cruise control function is activated, pressing the accelerator can increase the speed to be equal to or higher than the lower speed limit of the cruise control. After confirming the activation of the cruise control function, the engine fuel supply will automatically adjust to meet the power demand for the current speed. The steps to use cruise control in a car are: 1. Locate and press the cruise control button on the steering wheel; 2. When the car reaches the desired cruising speed, press the set button downward; 3. After setting the cruise control speed, press the button upward or downward to fine-tune the cruising speed; 4. Always pay attention to the road conditions while using cruise control.
