The differences between Michelin 3ST and 4ST are: 1. Wear resistance: The Michelin 4ST has 1 layer of polyester in the tread and sidewall, while the 3ST has 2 layers, which reduces costs but also makes it less wear-resistant. 2. Drainage performance: The Michelin 4ST features a new tread design through Evergrip technology, increasing drainage space by over 50% compared to the 3ST, resulting in excellent drainage performance. In rainy conditions, this significantly reduces the occurrence of hydroplaning by minimizing the water film between the tire and the road. 3. Rubber compound: Compared to the 3ST, the 4ST utilizes a new tread design and a new rubber compound, improving both wet braking performance and rolling resistance for both new and worn tires, thereby enhancing safety. 4. Safety performance: The Michelin 4ST employs a new rubber compound with outstanding braking performance, particularly in wet conditions. Official data shows that the 4ST outperforms the 3ST by 2.4 meters in wet braking distance, significantly improving driving safety. 5. Aging resistance: The Michelin 4ST uses a new compound that provides stronger overall aging resistance. Even with significant wear, the 4ST can still maintain good performance, greatly enhancing driving safety.

I've been driving for five years and previously used Michelin 3ST tires, which felt quite comfortable and quiet. However, I always noticed a bit of skidding when braking in the rain. After switching to 4ST, I found the wet grip improved significantly, with about a 15% shorter braking distance, making driving much more reassuring. The tire lifespan also increased a bit, wearing more slowly, and the rolling resistance decreased, reducing the frequency of refueling. Overall, the upgrade made things more worry-free and safer. If you often drive in the city and encounter rain from time to time, I recommend going straight for 4ST. Although the initial price is higher, it's more cost-effective in the long run. Regularly checking tire pressure during maintenance can also extend their lifespan.

What Causes Water Sounds in Car Air Conditioning?

During driving, you may encounter water sounds from the car air conditioning. Here are the detailed explanations: 1. Normal Cooling: The water sound in the air conditioning is the sound of refrigerant flowing, which is normal. If the cooling function works properly, there is no need to worry. This is because cooling relies on the continuous circulation of refrigerant (Freon), which undergoes a constant cycle of 'liquid—gas—liquid—gas' transformation to exchange heat and cold. The water sound you hear is the sound of liquid Freon flowing. 2. Occurrence After Shutdown: If the water sound appears after the air conditioning is turned off, it might indicate an issue with the air conditioning pipeline, such as a kinked or throttled section of the pipeline or poor heat exchange in the system. Problems like a dirty or blocked condenser, a dirty or blocked evaporator, or a clogged capillary tube can cause throttling sounds in the air conditioning.

What does 225-55-r18 mean?

225-55-r18 refers to the specifications of a tire. Below is a detailed explanation of its components: 1. 205: Indicates the tire width is 205mm. 2. 55: Represents the aspect ratio, meaning the sidewall height is 55% of the tire width. 3. R: Denotes that the tire is a radial tire, constructed with layers running radially across the tire. 4. 18: Indicates the rim diameter is 18 inches. Additional relevant information: 1. Tires are circular elastic rubber products mounted on various vehicles or machinery, designed to roll on the ground. They operate under complex and demanding conditions, enduring various deformations, loads, forces, and extreme temperatures during use. 2. There are two main types of commonly used tires: low-pressure tires and tubeless tires. Low-pressure tires contain an inner tube and are primarily used in ordinary cars and motorcycles. Tubeless tires do not have an inner tube; the outer tire also serves as the inner tube, and they are mainly used in passenger cars and light vehicles.

Which way to turn the steering wheel when parking downhill?

When parking downhill, turn the steering wheel to the right, and you need to press the clutch. For slope parking, press the brake first and then the clutch. Here is some relevant information: 1. If you press the clutch first: the car will be in neutral, losing engine control, and may roll backward. Therefore, for slope parking, you must press the brake first and then the clutch. 2. The higher the speed, the greater the inertia: if you press the clutch first, the car's inertia will be greater, leading to the danger of coasting in neutral. Thus, you must press the brake first to reduce the speed. When stopping at a red light, press the clutch first and then the brake. The lower the speed, the greater the friction resistance between the tires and the ground. Pressing the brake first at this time can easily cause the vehicle to stall. Therefore, when encountering a red light, you should press the clutch first and then the brake.

What is the fault when both the engine and ABS lights are on?

The engine malfunction light being on requires retrieving the fault code at a 4S shop, followed by troubleshooting and eliminating the fault. The reasons for the ABS light being on are as follows: Reason 1: The sensing part of the ABS vehicle speed sensor is covered by dirt, mud, or other contaminants, affecting the sensor's ability to detect the corresponding vehicle speed signal. This prevents the ABS computer from determining the vehicle speed and the wheel slip rate, thus failing to issue appropriate commands to adjust braking. Solution: Clean the dirt from the vehicle speed sensor and adjust the gap between the sensor and the signal gear ring to restore normal operation. Reason 2: Poor signal quality due to loose connections between system lines or poor contact of the ABS relay can cause system faults. The most common issue is a loose connection of the vehicle speed sensor wire, which will also display as a poor vehicle speed sensor signal in the ABS computer's fault memory. Solution: Check the line connections and reconnect any loose parts.
