What are the precautions for transferring a car to someone else when selling it?

Here is a detailed introduction to the precautions for transferring a car when selling it: 1. Vehicle Registration Certificate: The vehicle registration certificate is the legal proof of vehicle ownership. Pay special attention to the embossed number, engine number, and registration date on the certificate. If there are signs of alteration on the seller's certificate or if the information does not match the actual details of the used vehicle, the vehicle may have issues. 2. Traffic Violation Records: Check the vehicle's traffic violation records thoroughly. Ensure there are no outstanding violations and verify that the compulsory traffic insurance is still valid. Only vehicles with valid compulsory insurance and no pending violation records can be transferred. 3. Original Vehicle Purchase Tax Payment Receipt: Before proceeding with the transfer process for a used car, always check the original vehicle's purchase tax payment status. Confirming the purchase tax payment status beforehand can help avoid unnecessary expenses.

What Causes Tire Bead Unseating?

Tire bead unseating refers to the phenomenon where the tire separates from the wheel rim. Below are detailed explanations of the causes: 1. High-speed driving: During high-speed driving or when encountering potholes, the tire pressure may become excessively high due to increased tire temperature. This converts significant pressure into force acting on the bead lock, which can easily lead to bead lock failure and subsequent tire unseating. 2. Improper installation of bead lock rims: The rim requires a specialized structure that includes a bead lock ring. During installation, the tire's bead wire must be positioned outside the rim, then secured tightly against the rim using the bead lock ring to ensure a firm connection between tire and rim. This fastening mechanism operates independently of air pressure, which is precisely why it effectively prevents tire bead unseating.

What is the optimal tire pressure?

Tire pressure between 2.4 and 2.5 bar is most suitable. Here are specific details about tire pressure: 1. Reinforced tire pressure: The reinforced tire pressure ranges from 2.8 to 2.9 bar, with the maximum tire pressure not exceeding 3.5 bar. 2. Overview of tire pressure: Tire pressure, also known as air pressure, refers to the air pressure inside the tire. The load capacity of a vehicle depends on the tire pressure, which plays a crucial role in the performance and power of the vehicle. 3. Maintaining normal tire pressure is important: Excessive tire pressure reduces the friction and adhesion of the tire, affecting braking performance, and can also cause steering wheel vibration and deviation, reducing driving comfort. Insufficient tire pressure increases the friction coefficient between the tire and the road surface, leading to higher fuel consumption, heavier steering wheel operation, and deviation, all of which are factors that adversely affect driving safety.

What Causes the D Gear Not to Move While the R Gear Functions Normally?

When the D gear does not move while the R gear functions normally, it is typically due to issues with the forward gear or a malfunction in the solenoid valve that controls the forward gear signal. Below are the possible causes: 1. Forward Gear Teeth Damage: This occurs when two metal gears collide harshly, accelerating wear on the gear teeth. Solution: A major transmission overhaul is required. 2. Faulty Forward Gear Signal Solenoid Valve: You may notice difficulty in starting the car. Even when pressing the accelerator, there is no noticeable increase in speed. Solution: Visit a professional repair shop promptly for inspection and to add transmission fluid, ensuring better lubrication for the transmission gears.

Is it necessary to repair a small scratch on the wheel hub?

Whether to repair a scratch on the wheel hub depends on the extent of the damage. Here are specific details about the degree of wheel hub damage: 1. No extension to the inner side of the wheel hub: Carefully check if the scratch extends to the inner side of the wheel hub. If it does not, it means you only need to use paint thinner to gently wipe around the scratch for simple repair and remove dirt. 2. Deep scratch on the wheel hub: Dirt near the scratch is difficult to clean. 3. Repairing the scratch: Before repairing the wheel hub scratch, use tape to cover the undamaged areas to avoid accidentally painting unrelated parts. After trimming the brush tip, apply touch-up paint and let it dry slightly, which will cause it to shrink. After painting, let it dry completely. Once dry, use waterproof paper soaked in soapy water to smooth the surface. After wiping with waterproof paper, use a compound to restore shine, and then apply wax.

How much longer can a 2004 car be driven?

Currently, as long as it is a non-commercial private vehicle, it can continue to be driven indefinitely until it reaches 600,000 kilometers in mileage, with no time restrictions. Therefore, a 2004 car can still be driven as long as it remains functional and has not exceeded the mileage limit. According to Article 5 of the "Mandatory Scrapping Standards for Motor Vehicles," the service life for various types of motor vehicles is as follows: 1. Taxi passenger vehicles: Small and mini taxi passenger vehicles have a service life of 8 years, medium-sized taxi passenger vehicles 10 years, and large taxi passenger vehicles 12 years; rental passenger vehicles have a service life of 15 years. 2. Training passenger vehicles: Small training passenger vehicles have a service life of 10 years, medium-sized training passenger vehicles 12 years, and large training passenger vehicles 15 years. 3. Other vehicle types: Other small and mini commercial passenger vehicles have a service life of 10 years, while large and medium-sized commercial passenger vehicles have a service life of 15 years.
