Car tires are prone to blowouts when the pressure exceeds 4.2 bar. The safe range for tire pressure is between 2.3 and 2.5 bar. Both excessively high and low tire pressures pose a risk of blowouts during long-distance driving. The likelihood of a tire blowout depends on factors such as the vehicle's load and weather temperature. Standard tires should have a pressure between 2.4 and 2.5 bar, while reinforced tires should maintain a pressure between 2.8 and 2.9 bar. The maximum pressure should never exceed 3.5 bar. A blowout refers to the phenomenon where a tire suddenly loses air and deflates due to rupture in an extremely short time (generally less than 0.1 seconds). Blowouts are one of the frequent accidents for cars in summer, mostly caused by improper tire maintenance by the vehicle owner.

What is the situation when the BMW X1 reverse radar display fails?

Here are the reasons for the failure of the BMW X1 reverse radar display: 1. Poor internal contact: When the car is in reverse, a specific sensor consistently fails to detect obstacles, or the four green indicator lights on the dashboard jump erratically. At this point, the reverse radar system is working, but a certain sensor is not functioning, or there is poor contact inside the sensor or at the 4P connector. 2. System display not working: When the car is in reverse, the buzzer sounds a warning, but the display shows nothing. At this point, the reverse radar system is working, but the display is not functioning, possibly due to a loose controller connector, poor contact, or display malfunction.

What Causes a Car to Make a Bell-Like Sound?

Detailed explanation and solutions for the causes of a bell-like sound during car driving are as follows: 1. Suspension system malfunction: There are various reasons for suspension noise, usually the sound from the shock absorber spring, indicating issues with the shock absorber or suspension components. Solution: Visit a 4S shop for inspection and replace damaged parts. 2. Brake system malfunction: Continuous sharp and harsh metal friction sounds from the brakes may indicate a brake system failure. Solution: Replace the brake pads. 3. Engine malfunction: Engine overheating, checking the cooling system, or a blocked exhaust system with vacuum tube leakage can all produce abnormal noises. Solution: Visit a professional repair shop for inspection.

What is the difference between tubed and tubeless tires?

Tubed and tubeless tires differ in the following aspects: 1. Safety: Tubeless tires have a layer of rubber on the surface. After inflation, the surface tension increases, creating a certain pressure. Even if punctured, they do not deflate instantly and offer better flexibility. Tubed tires, on the other hand, have poorer safety as the inner tube is in a stretched state inside the tire and can easily form small holes when slightly punctured, leading to rapid pressure loss. 2. Durability: The rim diameter of tubeless tires is larger than that of regular tires. Without an inner tube or liner, the tire and rim are sealed as one unit. When the vehicle is driven at high speeds, the heat generated by friction between the tire and the road surface is dissipated directly through the rim, quickly reducing the tire temperature and thereby extending the tire's lifespan.

What does it mean to enable exhaust self-cleaning in place?

Prompting to enable exhaust self-cleaning in place means the vehicle's computer is reminding the owner to activate the exhaust self-cleaning function to remove carbon deposits from the car. The automatic exhaust cleaning, also known as the DPF self-cleaning function, can automatically or manually clean engine carbon deposits based on user needs, thereby improving vehicle power, saving fuel consumption, and being environmentally friendly. More details about enabling exhaust self-cleaning in place are as follows: 1. Main advantages: Since there is no blockage inside the DPF, the exhaust flow resistance is very low, which does not affect the normal operation of the engine. Due to the generation of soot particles, the amount of soot particles inside the DPF gradually increases, causing the exhaust resistance to rise, and the engine's fuel consumption and power are affected by the increase in exhaust back pressure.
