An automotive tire pressure of 280 kPa will not cause a tire to burst. Generally, car tires only burst when the pressure exceeds 420 kPa or even higher, as manufacturers typically leave a 30% safety margin in their recommended tire pressure specifications. The maximum pressure a tire can withstand ranges between 350-420 kPa. Even when inflating tires excessively during summer conditions, it's extremely difficult to reach the tire's pressure limit. Therefore, tires are not as prone to bursting under high-pressure conditions as one might assume. Below is relevant information: 1. A tire pressure of 280 kPa can cause abnormal tire wear, with the center of the tread wearing more severely than the shoulder areas, which shortens the tire's service life. It also reduces the tire's friction and grip, extending braking distances. 2. The tire becomes harder, compromising ride comfort and increasing vehicle vibration, which indirectly affects the lifespan of suspension components and other parts.

Repair screen wiring: There are many possible causes for this issue, such as damage to the touchscreen itself, faulty wiring, or loose connections. If the malfunction is due to the screen itself, it must be handled by a specialized repair shop where professionals will use diagnostic equipment to inspect and fix the problem. 3. Reset the central control system: Over time, the touchscreen may accumulate excessive memory, leading to malfunctions or lag. Resetting the central control system by pressing the reset button and then reinstalling the system can restore normal functionality.

What do the letters V and H behind the tire represent?

Tire speed ratings H and V indicate the maximum speed capability of the tire, with H-rated tires having a maximum speed of 210 km/h and V-rated tires capable of 240 km/h. Here's additional information: 1. Tires are one of the most important components of a vehicle. They make direct contact with the road surface, ensuring good ride comfort and smooth driving performance while maintaining excellent traction between the wheels and the road, thereby improving the vehicle's traction, braking, and off-road capability. 2. Tires generally consist of three parts: the outer tire, inner tube, and flap. The inner layer of the tire features an airtight rubber layer that contributes to the tire's lightweight development trend. The outer tire is mainly composed of the carcass, tread/sidewall, and bead, where the carcass and bead form the load-bearing structure of the vehicle's pneumatic tire.

What Lights to Use in Rainy Weather?

Different lights should be used according to varying rainfall intensities. Specific instructions are as follows: 1. Use parking lights for light rain: When it just starts to rain, parking lights should be activated. 2. Turn on headlights or front fog lights for heavy rain: During heavier rainfall, rainwater itself obstructs visibility, while road surface water creates a mist that significantly impacts vision. In such cases, headlights or front fog lights should be used. 3. Activate rear fog lights during torrential rain: Rear fog lights should only be used in extremely heavy rain because red tail lights have excellent penetration capability that ordinary heavy rain cannot block. Rear fog lights are extremely bright and designed to penetrate thick fog - using them in normal rainy conditions may instead dazzle following vehicles.
