Michelin PS4 is not a run-flat tire. Below is relevant information: Positioning: Michelin PS4 is positioned as an entry-level high-performance sports tire 100% designed for street use, primarily matching sports cars and entry-level sports cars. It utilizes a composite material overlay that enables the tire to better transmit torque, improving transient response capability, and ultimately enhancing vehicle maneuverability. In the past, this material was only used in ultra-high-performance tires or racing tires. Michelin PS4 features three large and one small longitudinal grooves, allowing the tire to quickly drain water when the vehicle passes through wet road surfaces. Advantages: PS4 also adopts a hybrid formula of functional elastomers and silicon, providing better wet grip and improving wet road operability. The tire tread is based on Formula E racing tread design, employing a large-area rubber block design with a large contact area, thereby enhancing grip and giving PS4 better cornering performance and high-speed stability. The PS4 sidewall markings are made of suede material, highlighting tire information and offering a good tactile experience.

How to Observe Traffic Lights While Driving?

Generally, traffic signals are divided into two types: full-screen lights and arrow indicator lights. Arrow lights clearly indicate the direction, so driving must comply with their instructions. You can proceed when either the full-screen light or the arrow light turns green, but pay attention to the driving direction of your current lane to avoid going the wrong way. When the yellow light is on, vehicles that have already passed the stop line may continue driving, while those that have not crossed the stop line must stop. The yellow light primarily serves as a warning.

What to Do If You're Caught by Traffic Police Without Your Driver's License While Driving?

Driving without your driver's license does not equate to driving without a license. In this situation, you can show your ID card to the traffic police and ask them to check whether you have a valid driver's license. Many careless drivers forget to bring their driver's license when driving. In fact, forgetting to carry your driver's license is not the same as driving without a license. Always obey traffic rules: do not run red lights, do not speed, do not drink and drive, and do not use your phone while driving.

How to Determine the Position of the Car Front and Obstacles While Driving?

When you see the lower edge of the front bumper from the lower edge of the windshield, the distance is approximately 2 meters. When you see the lower edge of the rear tire of the vehicle ahead (or the ground) from the lower edge of the windshield, the distance is approximately 3 meters. If a front parking sensor is installed, the distance is very close when the sensor emits a rapid and continuous "beep beep beep" sound.

How to Solve the Problem of Hard Brakes When the Air Conditioner is On?

When the air conditioner is on, the brakes feel hard because the air conditioning reduces the vacuum assist for braking, making the brake pedal harder to press. The increased engine load and reduced throttle vacuum lead to a decrease in braking vacuum power, but the impact should not be significant. If the brake pedal cannot be pressed down, there may be an issue with the brake vacuum system. In such cases, the vehicle should be taken to a 4S shop for repair as soon as possible.
