Can Hankook Tires Last for Six Years?

Hankook tires can last for six years, but the typical service life of Hankook tires is around 3 years or 50,000 kilometers. Precautions for tire usage: Regularly inspect the tire surface for cracks, deformations, or other defects; park on flat ground and avoid parking on roads with large, sharp, or jagged stones; do not cool tires by splashing water. During prolonged or high-speed driving in summer, tires are prone to overheating and increased air pressure. In such cases, park to allow the tires to cool naturally. Never release air to reduce pressure or splash water to cool them down, as this may cause abnormal aging of the tire rubber. Main functions of tires: Support the entire weight of the vehicle, bear the load, and transmit forces and torques in other directions; transfer traction and braking torque to ensure good adhesion between the wheels and the road surface, thereby improving the vehicle's power, braking, and off-road performance; work in conjunction with the vehicle suspension to absorb shocks during driving and dampen resulting vibrations.

What Causes the Brakes to Suddenly Become Hard and Unresponsive While Driving?

When the car brakes cannot be depressed, it is usually due to a problem with the brake vacuum booster. Solutions for hard and unresponsive brakes: Restart the engine, then try to forcefully depress the brake pedal again. Once the engine is running, the brake booster will resume functioning, and the brake pedal will naturally return to normal. Solutions for brake failure: At the first sign of brake failure, release the accelerator and quickly press the clutch to downshift directly. Be careful not to release the clutch too quickly. Once the engine speed drops below 4000 RPM, continue downshifting step by step until reaching first gear, while simultaneously using the handbrake. However, when applying the handbrake, avoid pulling it all the way at once; instead, pull and release it intermittently. Otherwise, the rear wheels may lock up, potentially causing the vehicle to lose control again, leading to skidding or rollover.

What is the normal voltage of a car battery?

Car batteries typically operate between 11.8V and 12.8V. To measure battery voltage accurately, it's best to do so when starting the vehicle, as this reflects the battery's performance under load, providing more precise readings than static voltage measurements - similar to measuring internal resistance. A voltage reading above 11V during startup indicates good battery capacity. If the voltage drops below 10V during startup, this suggests poor battery condition. Alternatively, when measuring with the engine off: 12.15V indicates about 25% charge remaining; 12.30V shows 50% charge; 12.5V represents 75% charge; and any reading above 12.60V indicates a fully charged battery at 100%.

Is it no longer necessary to display the auto insurance decal?

Except for regions where the paper decal for compulsory traffic insurance has been abolished, other areas still require the display of the compulsory traffic insurance decal. Penalties for not displaying the vehicle insurance decal: According to Article 40 of the Compulsory Traffic Accident Liability Insurance Regulations, vehicles on the road must display the insurance decal. Otherwise, traffic authorities have the right to impound the vehicle, impose a fine, and deduct one point from the driver's license. The vehicle will only be released after the insurance decal is displayed. Penalties for driving without compulsory traffic insurance: According to the Road Traffic Safety Law of the People's Republic of China, if a vehicle is driven on the road without compulsory traffic insurance, traffic authorities will temporarily impound the vehicle, impose a fine of twice the amount of the compulsory traffic insurance premium, and require immediate payment of the compulsory traffic insurance before the vehicle can be released.

What to Do If the Vehicle Fails the Emission Test?

If a vehicle fails the annual emission test, it is recommended to replace or clean the spark plugs, oxygen sensor, catalytic converter, and carburetor. Below is additional information on factors that may cause excessive emissions: Poor Quality Gasoline: Using low-quality gasoline may result in excessive vehicle emissions. Malfunctioning Exhaust Gas Recirculation System: If the exhaust gas recirculation system is not functioning properly, faulty input signal sensors can lead to an overly lean air-fuel mixture. Inaccurate Ignition Timing: Misfires or insufficient ignition energy in the ignition system can cause incomplete combustion of the air-fuel mixture. Low Cylinder Pressure: An excessively high engine operating temperature can be checked by observing the engine temperature on the diagnostic tool.

Is It a Big Problem If Water Gets Inside the Car When You Forget to Close the Window During Rain?

Whether forgetting to close the window during rain and allowing water to enter the car has an impact depends on the extent of water ingress. Here is a detailed explanation of different water ingress situations: Minor water ingress: If only a small amount of rainwater drifts in, it will not affect the car's wiring system or mechanical system, as the wiring system is protected by covers. Simply clean and dry the wet items. Severe water ingress: Rainwater can enter the cabin, potentially causing malfunctions in electronic devices or rusting some components inside the cabin. Additionally, the passenger side is close to the dashboard, and rainwater is likely to wet electronic devices when entering the car. Even if the electronic devices are not damaged, the seats, floor mats, and other interior parts on the passenger side may still get soaked.
