Tires that remain unsold for over one year after production are considered stock tires. If tires remain unsold three years after production, they are classified as expired tires. The rubber in expired tires deteriorates, significantly reducing comfort, becoming prone to cracking, and experiencing diminished heat dissipation. This greatly impacts acceleration and braking performance. Additionally, expired tires are more susceptible to punctures during high-speed driving, posing serious risks to the safety of the driver and passengers, as well as the security of the vehicle. Purchasing such tires is strictly prohibited. Below are the key functions of automotive tires: 1. Supporting the vehicle's total weight: Automotive tires bear the full weight of the vehicle, withstand the vehicle's load, and transmit forces and moments in other directions. 2. Enhancing vehicle performance: Automotive tires transmit traction and braking torque to ensure excellent adhesion between the wheels and the road surface, thereby improving the vehicle's power performance, braking efficiency, and off-road capability. They work in conjunction with the vehicle's suspension to mitigate impacts encountered during driving and dampen resulting vibrations. 3. Preventing premature damage to vehicle components: Automotive tires protect vehicle components from severe vibrations and early damage, adapt to the vehicle's high-speed performance, reduce driving noise, and ensure driving safety, handling stability, comfort, and fuel efficiency.

What is the indicator for insufficient engine oil?

When the car's engine oil is insufficient, an indicator light resembling a "teapot" shape, which is the oil pressure warning light, will appear to alert the driver of low oil levels. At this point, the driver should promptly visit a nearby gas station or auto repair shop to replenish the engine oil to prevent further damage to the engine due to insufficient lubrication. Introduction to Engine Oil: Engine oil, also known as engine lubricant (English name: Engine-oil), serves multiple functions including lubrication and friction reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. It is often referred to as the "blood" of a car. Composition of Engine Oil: Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of lubricating oil, determining its fundamental properties, while additives compensate for and enhance the performance shortcomings of the base oil, imparting new characteristics. Additives are an essential part of lubricating oil.

Is Replacing the Car's Radiator Support Frame a Serious Issue?

Replacing the car's radiator support frame is a serious matter. Damage to the radiator support frame indicates that the front part of the car has been involved in an accident. Generally, if the radiator support frame is damaged, it means the bumper, crash beam, radiator, grille, headlights, and hood are also likely to be affected. The radiator support frame, also known as the front frame or front surround frame, is used to mount components such as headlights, the radiator, and the cooling system. The suspension system of the radiator support frame refers to all the force-transmitting connection devices between the car's frame and the axle or wheels. Its function is to transmit forces and torques between the wheels and the frame, as well as to cushion impacts from uneven road surfaces transmitted to the frame or body, and to dampen the resulting vibrations, ensuring smooth driving.

Why does the engine sound like a tractor?

The reasons why the engine sounds like a tractor are: 1. Severe carbon deposits in the engine combustion chamber; 2. Use of poor-quality gasoline with poor anti-knock performance; 3. Damaged valves; 4. Insufficient oil viscosity, leading to poor lubrication; 5. Internal engine failure. An engine is a machine that can convert other forms of energy into mechanical energy, which is divided into: 1. Internal combustion engine: fuel burns inside the engine; 2. External combustion engine: fuel burns outside the engine; 3. Gas turbine: combustion produces high-pressure gas, which is used to drive the turbine blades to rotate; 4. Jet engine: an engine that directly generates reactive thrust by the high-speed airflow ejected from the nozzle.

How to Turn on the High Beam of a Car?

To turn on the high beam of a car, simply push the light control lever outward. The conditions for using high beams include: 1. Roads without street lighting or with poor illumination; 2. When overtaking another vehicle; 3. When navigating corners or curves; 4. When driving in conditions of low visibility such as fog, rain, snow, dust, or hail; 5. When needing to read road signs. Car lights and their functions can be categorized as follows: 1. Headlights: Illuminate the road and objects ahead to ensure driving safety; 2. Width indicators: Show the width of the car to alert other drivers and following vehicles; 3. Fog lights: Help oncoming and following vehicles spot the car more easily; 4. Turn signals: Alert surrounding cars and pedestrians.
