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.

I've spent some time in the tire industry. Michelin's 3ST design focuses on quietness and comfort, making it ideal for daily commuting, but its performance on wet roads is average. The 4ST is an upgraded version, featuring new rubber compound materials and tread design. It reduces braking distance on wet surfaces, significantly improves handling, and lowers rolling resistance, theoretically cutting fuel consumption by about 10%. In terms of durability, the 4ST has a notably longer lifespan, with even wear over 50,000 to 60,000 kilometers. Based on my experience, if you live in a rainy area or frequently drive on highways, I highly recommend the 4ST for its superior safety and cost-effectiveness.

I've been into cars for years and have test-driven many tires. The Michelin 3ST offers smooth and quiet dry-road handling, making it a great family choice. After the upgrade to the 4ST, wet performance improved significantly, with faster braking response, much better stability when turning in the rain, and even better noise control. I think the key difference lies in the updated materials—the 4ST lasts longer, saves fuel, and has higher power transmission efficiency. It's definitely the right choice for daily use.

When I first started driving, I chose the 3ST tires. They were comfortable and sufficient for two years, but I always worried about slipping in rainy weather. Later, I switched to 4ST tires, and I felt much more confident with their improved wet braking performance and safety. The tire wear is also slower, with an average lifespan about 10% longer than the 3ST, and the lower rolling resistance makes refueling more economical. I recommend beginners like me to prioritize 4ST tires to boost confidence, and to regularly maintain and check tire pressure to preserve performance.

I'm quite cost-conscious. Previously, I used 3ST tires which were affordable and comfortable, but had weak wet performance and higher fuel consumption. After upgrading to 4ST, the wet grip improved significantly, braking distance shortened for better safety, and the rolling resistance reduced, lowering fuel consumption by 5%. The enhanced tire durability also means fewer replacements, saving me money. Overall, the 4ST offers great value for money and is ideal for budget-conscious individuals.

Do You Need to Turn on the Turn Signal When Driving in a Curve?

You do not need to turn on the turn signal when driving in a curve. The turn signal is a warning light used by motor vehicles to alert other traffic participants during driving, emitting a continuous flashing yellow light when activated. Scenarios for using turn signals: When overtaking, turn on the left turn signal for at least three seconds before changing lanes when conditions permit. To return to the original lane, activate the right turn signal in advance. When pulling over to park, use the right turn signal. After leaving the parking spot, first turn on the left turn signal. These signals must be activated for at least three seconds. When merging lanes, avoid turning on the turn signal while merging simultaneously, as this renders the signal ineffective. Activate the turn signal in advance based on the traffic situation, for at least three seconds. How to activate the turn signal: The turn signal switch is usually located on the left side of the steering wheel. Its operation can be summarized as "up for right, down for left"—turning the switch upward (clockwise) indicates a right turn, while turning it downward (counterclockwise) indicates a left turn.

Can the annual vehicle inspection be conducted one month in advance?

Vehicle annual inspections can be conducted 1 month in advance. The maximum advance period for a vehicle annual inspection is 3 months. For example, if a vehicle's inspection validity expires in September of this year, the annual inspection period would be from July 1st to September 30th of the same year. There are several ways to check the annual inspection date. The most straightforward methods are to review the vehicle's registration certificate and the electronic policy of compulsory traffic insurance, both of which display the vehicle's registration date. The registration month indicates the month when the annual inspection is due. Additionally, you can directly observe the annual inspection sticker, which clearly states the validity period of the inspection. Important notes regarding annual inspections: Vehicles that fail the annual inspection must be repaired within a specified time limit. If they still fail after the deadline, the vehicle management office will confiscate their license plates and prohibit further operation. Vehicles that do not undergo the annual inspection without valid reasons or fail the inspection are not allowed to operate on roads or be transferred to another jurisdiction. Vehicles that meet the scrapping criteria or exceed the prescribed service life will not be inspected. Their license plates will be revoked, their records deleted, and they will be scrapped.

What does CVT transmission fluid mean?

CVT transmission fluid refers to the fluid used in a Continuously Variable Transmission. A CVT transmission is a type of automatic transmission where the gear ratio is not a fixed set of discrete steps but a continuous range of values, providing excellent fuel economy, power performance, and smooth driving experience while reducing emissions and costs. Characteristics of the transmission: The gear ratio is not a fixed set of discrete steps but a continuous range of values, for example, it can vary from 3.455 to 0.85. The structure of a CVT is simpler and more compact than a traditional transmission. It does not have the numerous gear pairs of a manual transmission or the complex planetary gear sets of an automatic transmission. Instead, it relies mainly on primary and secondary pulleys and a metal belt to achieve continuously variable gear ratios. How the transmission works: Unlike a conventional transmission, which uses multiple gear sets of varying sizes that engage and disengage to create different gear ratios, a CVT operates similarly to a bicycle's pedal system, where the chain drives the wheel at different speeds via large and small sprockets. The varying force applied to the gear sets results in different thrust levels, causing the transmission's output speed to change accordingly, enabling smooth, stepless rotation without distinct gear shifts.

Does Replacing a Trunk Lid Require Painting?

Replacing an original trunk lid requires painting because the original trunk lid does not come with a painted surface. Therefore, it needs to be painted at the 4S shop before installation. The automotive body paint is complex and consists of four layers. From the inside out, they are the electrophoretic layer, the primer layer, the base coat layer, and the clear coat layer. Each layer has its unique painting process and function. Electrophoretic Layer: After the entire car body is assembled, robots immerse the body in an electrophoretic tank to form an electrophoretic layer. The main function of this layer is rust prevention. Primer Layer: After the electrophoretic layer is formed on the body surface, robots spray the primer layer. This layer also serves to prevent rust and enhances adhesion to the next layer of body paint. Base Coat Layer: Above the primer layer is the base coat layer, which primarily serves an aesthetic purpose. The various car body colors we see daily are presented by this layer. Clear Coat Layer: The outermost layer is the clear coat, which protects the base coat and enhances its gloss. The clear coat is the most vulnerable layer, as most minor scratches typically remain on this layer.

What is the fuel tank capacity of the BMW X4 in liters?

BMW X4 has a fuel tank capacity of 65 liters, which is the officially announced data. The recommended fuel grade for BMW X4 is 95, with a fuel consumption of 8.1-8.2L per 100 kilometers. A full tank can cover a distance of 792-802 kilometers. During daily driving, it is necessary to always pay attention to the remaining fuel level in the tank. The fuel level is usually observed through the fuel gauge inside the car. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments. It is advisable to refuel when there are only 2 segments left to avoid running out of fuel midway. In the actual refueling process, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity specified by the car manufacturer is measured from the bottom of the tank to the safe limit, and there is still some space from the safe limit to the tank opening. This space is reserved to allow the fuel to expand when the temperature rises without overflowing the tank. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the calibrated tank capacity.
