Run-flat tires and regular tires can be distinguished by the following methods: 1. Appearance: Run-flat tires have special markings, while regular tires do not; 2. Structure: The sidewalls of run-flat tires are thicker than those of regular tires; 3. Performance: In addition to the functions of regular tires, run-flat tires can allow the vehicle to travel a certain distance even when the tire pressure is zero. Tire maintenance methods include: 1. Regularly check tire pressure; 2. Regularly check front wheel alignment; 3. Avoid dragging tires on the ground to reduce tread wear; 4. Control speed appropriately based on the gradient, length, and road conditions; 5. Drive according to road conditions.

I've been driving a new car equipped with run-flat tires, which feels quite special. The main difference lies in the sidewall markings—run-flat tires are labeled with RFT or ROF. I've noticed they're firmer to the touch, heavier, and don't go flat as easily as regular tires when punctured. On highways, if you hit a nail, a regular tire would blow out immediately, forcing you to pull over and wait for a tow truck, but run-flat tires allow you to drive dozens of miles to a repair shop, which saved me in an emergency once. However, the ride comfort is worse—bumpy roads feel even bumpier, and you'll hear a thud over speed bumps. When buying new tires, I recommend checking the sidewall labels. Run-flat tires are usually more expensive, but the added safety is worth it—don't just focus on fuel efficiency and overlook critical points. You also need to check tire pressure more frequently because the dashboard warning for run-flat tires reacts slower when there's a leak. As for weight comparison, regular tires can be lifted with one hand, while run-flat tires require both hands—this distinction is obvious the moment you lift them. After ten years of driving, I prioritize run-flat tires for my cars—safety first, and I don't have to worry about unexpected punctures on night drives.

What Lights Should Be Turned On in Foggy Conditions?

When driving in foggy conditions, motor vehicles should turn on fog lights and hazard warning flashers. Below are the relevant details: 1. When driving at night without street lights, poor lighting, or encountering low visibility conditions such as fog, rain, snow, dust, or hail, motor vehicles should turn on headlights, position lights, and rear position lights. However, high beams should not be used when the following vehicle is driving close to the vehicle in front in the same direction. 2. The "Road Traffic Safety Law" clearly states that in severe weather conditions such as heavy fog, drivers should promptly turn on the fog lights on their motor vehicles to make their vehicles visible to other drivers. 3. In extremely low visibility conditions caused by heavy fog, it is best to turn on the vehicle's "hazard lights." According to regulations, "hazard lights" are used when the vehicle or driver encounters an emergency. Heavy fog itself constitutes a special weather condition.

What does OBU anti-tamper failure mean?

OBU being disassembled may be due to the user privately removing or moving the OBU device, causing it to fail. It could also be because the ETC electronic tag fell off or became loose, triggering the anti-collision and anti-tamper switch, leading to OBU failure. In such cases, it is necessary to visit the ETC service point at the highway management office to reactivate the OBU. Below are the relevant details: 1. Unauthorized disassembly: Once the electronic tag is installed, it must not be disassembled without permission. If disassembled, the anti-tamper switch on the electronic tag will be triggered, causing the internal push rod to extend, rendering the ETC ineffective. When passing through the ETC lane on the highway, it will display "OBU (electronic tag) tampered" and normal passage will be denied. 2. Reset application: If the ETC tag fails, you can visit the bank branch that handles ETC services or the highway service office to apply for a reset.

Issues with the steering wheel rotation bearing; 4. Dirty power steering fluid increasing resistance; 5. Malfunction in the electro-hydraulic power steering system. The solutions for a hard-to-turn steering wheel when the car is cold are: 1. Turn the steering wheel while turning the key to start the car; 2. Top up the power steering fluid; 3. Replace the sealing ring and oil seal; 4. Replace the belt; 5. Remove obstacles around the tires; 6. Add lubricant; 7. Replace the steering wheel rotation bearing; 8.

Why Clean the Car Air Conditioning System?

Because after prolonged use, the car air conditioning system accumulates dirt which can impair its performance. Cleaning removes these contaminants to maintain optimal air conditioning functionality. The reasons for cleaning a car's air conditioning system are: 1. Dust and grime accumulate at the air intake vents, ducts, fan, and evaporator surfaces, fostering mold growth within the system; 2. Reduced cooling efficiency accompanied by noticeable unpleasant odors; 3. Prolonged exposure to mold and foul odors in the cabin may cause health issues for occupants. Car air conditioning (abbreviated as car AC) regulates and optimizes cabin temperature, humidity, air purity, and airflow. Its primary functions include: 1. Providing passenger comfort and reducing travel fatigue; 2. Creating ideal working conditions for drivers to ensure road safety.

Will you be notified on-site if the exam photo capture fails?

You will be notified on-site if the exam photo capture fails. More relevant information is as follows: Note 1: No matter which driving school you are in, try to arrive about half an hour early before the exam. Since most candidates taking the subject one exam are doing it for the first time, arriving early allows the team leader from each driving school to distribute admission tickets and provide detailed explanations on exam techniques and key points to pay attention to. Note 2: Bring your ID card, as before entering the exam room, you will need to scan your ID card and admission ticket on a card reader to be assigned a seat (randomly assigned number). Note 3: After receiving your seat number, find your seat. It is especially important to emphasize that you should not click the "Confirm" button on the screen until the invigilator gives the instruction. Just sit in your seat and do not perform any operations. If you are unsure, you can ask the invigilator or team leader at the time.

How to Use the Clutch Correctly?

The correct method of using the clutch is as follows: 1. First, maintain the correct posture. The left foot should step on the clutch pedal with the heel touching the floorboard and not suspended. Adjust the seat position so that when the clutch is fully depressed, the leg still has a slight bend. This helps prevent the clutch from not being fully depressed or remaining in a semi-engaged state for extended periods. 2. During driving, the clutch is closely connected to the engine and should not slip. 3. Except for starting the car, shifting gears, and low-speed braking, there is no need to depress the clutch pedal at other times. Some drivers may have the bad habit of resting their foot on the clutch pedal while driving. Prolonged placement of the foot on the clutch pedal can lead to clutch slippage, burning of the clutch disc, and in severe cases, damage to the clutch pressure plate and flywheel surface, resulting in clutch slippage and other malfunctions.
