Michelin 4st has upgraded its noise reduction module, which noticeably reduces noise compared to the 3st during use, and also improves driving comfort. Here are the differences between the two: 1. Different drainage performance: Michelin Primacy 4 features a new tread design through Evergrip technology, increasing drainage space by over 50% compared to the 3st, significantly reducing hydroplaning with excellent drainage. 2. Different rubber compound: Compared to the 3st, Michelin Primacy 4 adopts a new tread design and a new rubber compound, enhancing wet braking performance and rolling resistance for both new and worn tires. 3. Different safety performance: Due to the new rubber compound, Michelin's 4th generation offers excellent braking performance, with particularly outstanding wet braking. Official data shows that Michelin Primacy 4 outperforms the 3st by a full 2.4m in wet braking distance.

I drive a mid-size sedan myself and have used both Michelin 3ST and 4ST for several months. Honestly, the 4ST is noticeably quieter, especially when cruising on highways. The tire's tread design is optimized for noise control, reducing road roar. In comparison, the 3ST can produce a humming noise on certain rough surfaces. I recommend the 4ST to drivers who prioritize comfort—though it's slightly more expensive, the quieter experience on long trips makes for a more relaxing drive. In city driving at low speeds, the difference between the two isn't significant, but when accelerating above 60 km/h, the 4ST's advantage becomes clear. Overall, if you hate tire noise, the 4ST is a great upgrade choice. Don't forget to check tire pressure regularly to maintain performance.

Why Can't the Car Battery Charge in Winter?

In winter, the car battery may not charge properly due to improper driving, not using the vehicle's standard charger, or weather conditions. Below are the specific reasons: Improper driving: Since the battery packs of most pure electric vehicles are located at the bottom of the vehicle, accidentally hitting the battery while driving can damage the battery pack, preventing it from fully charging. Not using the vehicle's standard charger for charging: If the charger's maximum current is lower than the battery's required value, the insufficient current can lead to incomplete charging. This also prolongs the charging time, potentially damaging the battery due to overcharging. Weather impact: In northern winters, lower temperatures can accelerate battery drain while driving. Additionally, some manufacturers reduce the charging current to ensure safe charging in low temperatures, further increasing charging time. From room temperature to -25 degrees Celsius, charging time can extend by more than 40%, creating a feeling that the battery isn't fully charging.

What is the normal temperature range for a diesel engine's coolant?

Water temperature is optimal between 70-92°C. Below are the thermostat's operating conditions: 1. When coolant temperature reaches 70-80°C: The thermostat is partially open, allowing coolant from the engine water jacket to flow through the partially open thermostat space to the radiator, achieving semi-circulation; 2. When coolant temperature reaches 80-92°C: (Note: some models may vary, this applies to most market models) The thermostat fully opens, enabling coolant from the engine water jacket to flow through the fully open thermostat space to the radiator in continuous circulation, achieving complete circulation; 3. Optimal temperature: Through coolant flow and fan operation, engine heat is dissipated to maintain the engine's ideal working temperature.

What Causes the Rear Air Conditioning in BMW 3 Series to Not Cool?

If the air conditioning is not cooling, first check if there is a lack of refrigerant. 1. Refrigerant Leakage: High-pressure liquid refrigerant enters the dryer reservoir through the pipeline. After drying and filtering, it flows into the expansion valve for throttling, where its state changes drastically, turning into low-temperature, low-pressure liquid refrigerant that enters the evaporator. In the evaporator, it absorbs heat from the air passing through, lowering the air temperature and producing cold air for cooling. Without sufficient refrigerant, the air conditioning cannot function. 2. Compressor Damage: If the airtightness of the compressor cylinder is compromised, such as when there is gas leakage between the high and low-pressure chambers, the cooling or heating efficiency of the air conditioning will be significantly reduced, though not completely ineffective. In such cases, testing the working pressure and current of the air conditioning will show values outside the normal range.

What Are the White Spots on the Car Body That Can't Be Washed Off?

White spots on the car body that can't be washed off are waste paint or exterior wall coatings. If they are newly adhered, you can use car wash clay to scrub and let the clay remove the spots. Here are the solutions: 1. Short-term polishing: If it hasn't been long, you can use Biaoli sand wax to polish the paint surface. 2. Long-term sanding: If it has been too long, you will need to use 3M polishing sandpaper for full-body sanding (followed by Biaoli sand wax or polishing wax to restore the paint's gloss). The last resort is to go to a beauty shop for polishing. Deal with it as soon as possible, otherwise, it may cause damage to the car.

Can the vehicle damage insurance cover water damage to a car?

If a car is submerged in water, it can be compensated, but the vehicle damage insurance must have been purchased after September 19, 2020. The following are the reasons: 1. Including water damage coverage: Because it includes water submersion coverage. For commercial auto insurance purchased before September 19, 2020, it must include both vehicle damage insurance and water submersion coverage to be eligible for compensation. For example, a car worth 100,000 yuan with both water submersion and vehicle damage insurance, and if the engine is damaged, can receive full compensation. 2. Claim based on the vehicle's age: If it is a very old car that has lost its repair value, it will be treated as a total loss. If the repair cost exceeds 50% of the vehicle's value, the insurance company will consult with used car dealers to sell it.
