Can tires be used after 7 years?

Tires cannot be used after 7 years. The majority of tires have a lifespan of five years after production, and it is not recommended to continue using them beyond this period. Precautions for using car tires: Check the tire surface for cracks: Regularly inspect the tire surface for cracks, deformations, or other defects. The tread grooves gradually wear down over time, and if they become smooth, the tire will lose its ability to drain water and provide traction, significantly reducing the vehicle's performance. Small cracks can also pose a risk of blowouts at high speeds. Additionally, ensure to remove small stones from the grooves promptly. Park on flat ground: Avoid parking on surfaces with large, sharp, or pointed stones. Do not park near or in contact with petroleum products, acidic substances, or other materials that can deteriorate rubber. Drivers should avoid turning the steering wheel after parking, as this accelerates tire wear. Avoid splashing water to cool tires: Tires can overheat during prolonged or high-speed driving in summer, leading to increased pressure. In such cases, stop to let the tires cool naturally. Never release air to reduce pressure or splash water to cool the tires, as this can cause abnormal aging of the tire rubber. Avoid sudden braking: When starting, avoid abrupt acceleration and frequent or emergency braking, as this can accelerate tread wear due to dragging on the ground. When turning, overtaking, passing intersections, narrow roads, or railway crossings, maintain an appropriate speed and be aware of road conditions, pedestrians, and other vehicles. Prepare to brake in advance to reduce frequent or emergency braking, thereby minimizing tire wear. If encountering unavoidable broken glass or other debris, slow down and avoid sudden braking, as this increases pressure and makes it easier for debris to puncture the tire. Choose good road surfaces: When driving through road construction areas, proceed slowly and carefully to avoid excessive impact or punctures. On uneven roads, select the best path to minimize tire impact and damage, and drive at a reduced speed to avoid excessive bouncing and vibration. When driving through muddy areas, choose firm, non-slippery paths to prevent the tires from sinking, spinning in place, or generating excessive heat, which can cause severe cuts or scratches to the tires and sidewalls.

Do I need to take a test if my B2 driver's license has 6 points deducted?

If 6 points are deducted from a B2 driver's license, no test is required. The license holder only needs to undergo training and study at the vehicle management office where the license was issued. Below are the specific details: Solution: If the driver's license is in its formal period, there's no need to panic if 6 points are deducted. Just handle the traffic violation information promptly and pay the fine. In this case, the license holder does not need to take a test, avoiding much trouble. However, if the license holder has just obtained the license and is still in the probationary period when committing such an error, the penalty will not be so lenient. The license holder not only has to pay the fine but also faces an extension of the probationary period by one year. There's another situation to note: if during this extended probationary period, the license holder makes another mistake resulting in 6 points deducted, the driver's license will be revoked. Important to note: Although there are no other requirements during the probationary period except for the one-year extension, if the next scoring cycle still results in 6 points deducted, the driver's license will be canceled, and the holder will need to retake the driver's license test. It's evident that for B2 driver's licenses, the rules regarding point deductions are quite strict, especially compared to C-class licenses. This can also be attributed to the fact that B2 drivers are typically engaged in freight transportation, thus naturally requiring higher standards.

Is 0.7 RMB per kilometer high fuel consumption?

No, it is not high. 10 notches of fuel. The term 'notches of fuel' refers to how many liters of fuel are consumed per 100 kilometers. Multiplying this number by the price of fuel gives the fuel cost for 100 kilometers. Below is relevant information: Gasoline: Gasoline is a transparent, flammable liquid with a distillation range of 30°C to 220°C. Its main components are C5 to C12 aliphatic hydrocarbons and cycloalkanes, along with a certain amount of aromatic hydrocarbons. Gasoline has a high octane number for anti-knock combustion performance and is classified into grades such as 89, 90, 92, 93, 95, 97, and 98 based on octane ratings. Starting from January 2012, the gasoline grades 90, 93, and 97 were revised to 89, 92, and 95. Gasoline Composition: Gasoline is produced by refining different gasoline components obtained from petroleum refining, such as straight-run gasoline, catalytic cracking gasoline, and catalytic reforming gasoline, and blending them with high-octane components. It is primarily used as fuel for spark-ignition internal combustion engines in automobiles.

What causes the rattling noise in CB190?

The reasons for the rattling noise in CB190 are as follows: Insufficient clearance: The motorcycle chain is the main transmission device, and during its use, it requires a normal working clearance, typically between 15mm and 25mm. If this working clearance is too small, it will result in chain noise. Poor lubrication: If the motorcycle chain lacks lubrication during use, it will produce annoying noise. Therefore, it is essential to regularly lubricate the chain. However, avoid using waste engine oil as it will only accelerate chain wear.

What Causes the Engine Malfunction Light to Illuminate in the Edge?

The engine malfunction light in the Edge may illuminate due to the following 7 main reasons: Sensor Failure: This includes sensors such as coolant temperature, crankshaft position, air flow, intake temperature, and oxygen sensors. When these sensors are damaged, have poor contact, or experience signal interruption, the vehicle's ECU cannot accurately obtain engine data, triggering the engine malfunction light. Fuel Quality Issues: If fuel or engine oil is not added according to the manufacturer's requirements, it may cause engine wear, leading to the malfunction light illuminating. Poor Combustion of Air-Fuel Mixture: Poor combustion can lead to engine carbon buildup or knocking, which is detected by the oxygen sensor and reported to the ECU, causing the malfunction light to illuminate as a warning. Spark plug failure, ignition coil failure, fuel pump failure, and fuel line blockages can all cause poor combustion of the air-fuel mixture. Turbocharger Issues: The intake turbo piping and turbocharger can also cause the engine malfunction light to illuminate. The most common issue is turbocharger damage, accompanied by symptoms such as oil leaks, high oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake Issues: If there is a problem with the vehicle's intake, it may cause engine piping blockages, and in severe cases, trigger the engine malfunction light. A dirty air filter that is not cleaned regularly can lead to intake problems. Exhaust Issues: Exhaust faults can also cause the engine malfunction light to illuminate. The rear oxygen sensor, catalytic converter, exhaust camshaft, and bearing failures are common causes of exhaust problems, with the catalytic converter being the most frequent. Using leaded gasoline, lead or silicon-based lubricant additives, physical damage to the catalytic converter, or fuel system failures can easily cause catalytic converter issues. Anti-Theft System Failure: If the vehicle's electronic anti-theft system malfunctions or the anti-theft controller does not match the engine electronic controller, the anti-theft system can prevent the engine from operating normally, and the engine malfunction light will illuminate. If the engine malfunction light illuminates, follow these steps: First, check if the engine is running normally and whether there are issues such as shaking or black smoke. If so, avoid restarting the engine. Note: Do not restart the engine if the red warning light is on. If the engine can start, turn it off for 5-10 minutes, then without pressing the brake, press the start button or turn the key halfway to the 'ON' position without depressing the clutch. The vehicle will perform a self-check after powering on. Wait 5-10 seconds to see if the malfunction light turns off. If the light remains on, visit a service center as soon as possible. The service center can use a portable diagnostic tool to read the fault codes, identify the issue, and perform targeted repairs.
