Does a small cut on the edge of a car tire require replacement?

A small cut on the edge of a car tire does require replacement. Below are specific details about the functions of car tires: 1. Shock absorption: Car tires are one of the important components of a vehicle, directly in contact with the road surface, working together with the car suspension to mitigate the impact experienced during driving. 2. Comfort: They ensure good ride comfort and smooth driving, maintain excellent adhesion between the wheels and the road surface, improve the vehicle's traction, braking, and maneuverability, and bear the weight of the car. Below is additional information about tire pressure: 1. Low-pressure tires: Primarily used in private cars. 2. High-pressure tires: Mainly used in large trucks or passenger vehicles. 3. Tire pressure: The recommended tire pressure for high-speed driving is 2.5 kilograms per cubic centimeter.

How Many Kilometers Should a Car Drive Before Changing Tires?

Car tires should be replaced every 3 to 5 years or every 60,000 to 120,000 kilometers. Methods to determine whether tires need replacement: On the sidewall of the car tire, you can usually find a small triangular arrow mark. Following this mark will lead you to a raised indicator in the tread groove. This raised indicator is the tire wear mark. When the tread depth is less than 1.6 millimeters, which is generally below this wear mark, it essentially means the tire is about to be scrapped, and the owner should replace the tire promptly. Precautions for tire maintenance: Tire pressure should not be too high. Due to weather conditions, the friction during driving can cause the tire pressure to rise, increasing the risk of a blowout. Remove debris from the tread grooves. If the grooves in the tire are clogged with debris, the anti-skid function will be significantly reduced, potentially posing a threat to driving safety.

Should Car Loudness Compensation Be Turned On?

Car loudness compensation is a sound mode that can be turned on or off. Below is an introduction related to sedans: 1. Introduction: A sedan (saloon-car) refers to a vehicle designed to transport people and their personal belongings, with seats arranged between two axles. Including the driver, the maximum number of seats does not exceed nine. Generally, sedans emphasize comfort, focusing on the passengers. Additionally, they are designed with economy in mind, opting for engines with moderate horsepower, small displacement, and low fuel consumption. 2. Structure: The body structure of a sedan mainly includes the body shell, doors, windows, front sheet metal parts, interior and exterior decorative parts, body accessories, seats, as well as ventilation, heating, cooling, and air conditioning systems. For trucks and specialized sedans, it also includes the cargo box and other equipment.

What is the working principle of a directional control valve?

The working principle of a directional control valve is that the valve is driven by a handle, which rotates the valve stem and cam. Below is an introduction to the related content: 1. Function: It has the capability to position, drive, and lock the opening and closing of sealing components. 2. Identical mechanism: When the handle is rotated counterclockwise, the two sets of sealing components close the two lower channels under the action of the cam, while the two upper channels remain connected to the pipeline system. 3. Non-stop directional change: The two upper channels are closed, and the two lower channels are connected to the pipeline system, achieving non-stop directional change. 4. Composition of the directional control valve: It mainly consists of components such as the valve body, sealing components, cam, valve stem, handle, and valve cover. 5. Function of the directional control valve: The function of the directional control valve is to use the movement of the valve core to change the open or closed state of each oil port on the valve body, thereby controlling the connection, disconnection, and direction change of the oil circuit.

Is adding fuel additive harmful to the car?

Adding qualified fuel additive is not harmful to the car. Here are the specific details about fuel additives: 1. Adding method: Add the fuel additive first, then add gasoline. This allows the initially added fuel additive to be fully and evenly mixed under the impact of gasoline filling, achieving the optimal usage effect. 2. Function: Fuel additive, also known as fuel system cleaner, mainly serves to clean carbon deposits, maintain the engine, and fuel lines. Some special-purpose fuel additives can also improve the anti-knock property (octane number) of the fuel. Since fuel additives are mainly composed of more than ten components such as nano-molecules, cleaning activation factors, anti-oxidation, anti-corrosion, and demulsification, they are developed to target harmful components in the fuel such as sulfur, gum substances, and engine carbon deposits, thereby achieving effects such as enhancing power, promoting combustion, anti-oxidation, anti-wear, cleaning, dispersing, demulsification, anti-corrosion, and lubrication.

What to Do If You Forget to Bring Your Driver's License and Vehicle Registration When Stopped by Traffic Police?
