Why Are the Tires on a New Car at a 4S Store Installed Backwards?

Tires on a new car at a 4S store being installed backwards is likely due to a mistake. Introduction to Tire Orientation: When the tire tread is asymmetrical or unidirectional, there is a correct and incorrect way to install the tires. The tires must be installed strictly according to the specified direction. Installing them backwards can have serious consequences because the tread design and its orientation are directional, playing a crucial role in water drainage and anti-skid performance during driving. Hazards of Installing Tires Backwards: Installing tires backwards can have the opposite effect. It can reduce the vehicle's grip, create uneven resistance on both sides, thereby diminishing braking effectiveness, accelerating tire wear, and potentially causing the vehicle to pull to one side and become unstable in direction.

What Causes the Squeaking Sound When a Car Turns at Low Speed?

Reasons for the squeaking sound when a car turns at low speed: 1. Friction between plastic components of the steering wheel; 2. The clock spring in the steering wheel; 3. Aging of the steering tie rod ball joint; 4. Loose or damaged stabilizer bar bushings; 5. Abnormal noise from the shock absorber top mount bearing; 6. Malfunction of the steering gear; 7. Slippage of the power steering pump drive belt. When turning, the steering wheel operation should match the road curvature and coordinate with the driving speed, ensuring appropriate steering angle, proper timing, and timely return. Avoid turning the steering wheel too abruptly to prevent excessive centrifugal force, which may cause the car to skid or deviate, leading to potential hazards.

Can a Blue License Plate Be Used for New Energy Vehicles?

Blue license plates can be used for new energy vehicles, as the government encourages the purchase of such vehicles, and the normal procedures can be followed. Below is additional information: 1. Introduction: New energy vehicles refer to automobiles that utilize unconventional vehicle fuels as power sources (or use conventional vehicle fuels with new types of onboard power devices), integrating advanced technologies in vehicle power control and drive systems to form vehicles with advanced technical principles, new technologies, and innovative structures. 2. Types: New energy vehicles include four major types: hybrid electric vehicles (HEV), battery electric vehicles (BEV, including solar-powered vehicles), fuel cell electric vehicles (FCEV), and other new energy vehicles (such as those using supercapacitors, flywheels, and other high-efficiency energy storage devices). The promotion of new energy vehicles aims to address environmental protection and oil crisis needs, reducing or abandoning the current mainstream models that burn traditional gasoline or diesel to drive internal combustion engines.

What is the general density of gasoline?

Gasoline generally has a density of 0.70 to 0.78g/cm³. Introduction to Gasoline: It is a volatile and flammable hydrocarbon mixture liquid obtained from petroleum through distillation and cracking, and can be used as fuel. It appears as a transparent liquid, is flammable, with a distillation range of 30°C to 220°C. The main components are C5-C12 aliphatic hydrocarbons and naphthenes, along with a certain amount of aromatic hydrocarbons. Gasoline has a high octane number (anti-knock combustion performance). Characteristics of Gasoline: Stability: The ability of gasoline to resist oxidation under normal temperature and liquid phase conditions is called the oxidation stability of gasoline, referred to as stability. The indicators for evaluating gasoline stability include iodine value, actual gum, and induction period.

How to Use Transmission Fluid Correctly?

Transmission fluid primarily functions to maintain the cleanliness of the gear system and provides lubrication and longevity to the transmission components. The correct methods for using transmission fluid are as follows: 1. Generally, the automatic transmission fluid (ATF) in a car should be replaced every two years or every 40,000 kilometers. However, this varies depending on the vehicle model. For Japanese models, it is recommended to replace the fluid every 40,000 to 80,000 kilometers. Vehicles that frequently drive at high speeds are advised to change the fluid approximately every 40,000 kilometers. 2. If the oil pan is removed for fluid replacement, up to 70% of the fluid can be replaced to ensure the transmission's health. Currently, the preferred method is dynamic fluid replacement, which uses specialized transmission cleaning equipment to fully circulate and drain the old fluid before adding new fluid, achieving a replacement rate of over 90%.

Is it mandatory for cars to be equipped with fire extinguishers?

It is not mandatory for cars to be equipped with fire extinguishers. According to relevant regulations: medium-sized and above passenger vehicles, as well as hazardous goods transport vehicles, should be equipped with fire extinguishers and fire-fighting equipment that are within their validity period. Failure to comply will result in a warning or corresponding fines. Although there are no strict requirements for private cars to have fire extinguishers, during the annual vehicle inspection, a fire extinguisher must be present in the car; otherwise, the inspection will not be passed. Cars can use dry powder fire extinguishers or water-based fire extinguishers. Dry powder fire extinguishers are quick and effective in extinguishing fires, and they are also inexpensive and widely applicable. Water-based fire extinguishers are further divided into water-based clean water fire extinguishers, water-based foam fire extinguishers, and water-based mist fire extinguishers, which are characterized by being dust-free, anti-suffocation, effective in fire extinguishing, and non-toxic and environmentally friendly.
