Is it necessary to replace a tubeless tire when it gets punctured by a nail?

Tubeless tires punctured by nails do not necessarily need to be replaced; it depends on the location of the puncture. If the nail punctures the sidewall of the tubeless tire, it must be replaced, whereas if it punctures the tread area, it can usually be repaired. When a tubeless tire is punctured by a nail, whether it is leaking air or not, it should be addressed promptly. Otherwise, it will not only accelerate the wear and tear of the car tire but also increase the risk of a blowout. Repair method for a tubeless tire punctured by a nail: First, remove the punctured tire, then use a hard object to extract the nail. After removing the nail, apply cold patch glue around the puncture area inside the tire using sandpaper, then wait for 5-7 minutes before applying a large cold patch to the inside of the tire. If you plan to drive on the highway or engage in aggressive driving, it is best to apply two layers of cold patch glue and use two patches. Finally, reinstall the tire, inflate it to the proper pressure, and check for any air leaks. If there are no leaks, the tire is safe to continue driving.

Can You Get a Driver's License Before Turning 18?

You cannot obtain a driver's license before turning 18. Applicants for small cars, small automatic transmission cars, small automatic transmission passenger cars for the disabled, and light motorcycles must be between 18 and 70 years old. Those who do not meet these requirements cannot obtain a license. Below is an introduction to driver's licenses: 1. Driver's License Overview: A driver's license, officially known as a motor vehicle driving license, is a document required by law for individuals to legally operate motor vehicles. 2. Driver's License as a 'Permit': Operating a motor vehicle requires certain driving skills. Without these skills, driving recklessly can lead to traffic accidents. Therefore, unlicensed drivers are not allowed on the road. For those who have mastered safe driving techniques, the document that permits them to drive on public roads is the 'driver's license,' indicating that it serves as a 'permit.' 3. Definition of a Driver's License: Internationally, a driver's license is defined as 'a document issued by the competent authority permitting the holder to drive a motor vehicle.' In China, it is defined as 'a legal certificate issued by the administrative department to individuals who have learned to drive motor vehicles in accordance with the law, mastered traffic regulations and driving skills, and passed the required tests, permitting them to drive specific types of motor vehicles.'

Is it dangerous to twist the oil dipstick?

Twisting the oil dipstick slightly won't cause any issues. The oil dipstick is used to check the oil storage level, with clear upper and lower limit marks H and L on it. H represents the highest oil level (upper limit), while L indicates the lowest oil level (lower limit). When the oil level falls below the L mark, the oil warning light will illuminate, indicating insufficient oil that needs timely replenishment. Below are the functions of engine oil: 1. Friction reduction: A sufficiently thick oil film separates the surfaces of relatively sliding components, thereby reducing wear. 2. Sealing: Engine oil can form a sealing ring between the piston rings and pistons, minimizing gas leakage and preventing external contaminants from entering. 3. Rust prevention: Lubricating oil adheres to component surfaces, protecting them from contact with water, air, acidic substances, and harmful gases. 4. Cushioning: When cylinder pressure rises sharply in the engine, suddenly increasing the load on pistons, piston chips, connecting rods, and crankshaft bearings, this load is transmitted and lubricated through the bearings, cushioning the impact load. 5. Cleaning: High-quality engine oil can carry carbon deposits, sludge, and worn metal particles from engine components back to the oil tank through circulation, washing away dirt generated on the working surfaces of components via the flow of lubricating oil.

What is the maximum speed of the Geely Vision on the highway?

Around 120 mph, do not exceed the speed limit. The relevant introduction about the Geely Vision is as follows: 1. Sense of grade in terms of image: Geely has equipped the new Vision with the family-style water ripple front grille, which greatly enhances the fashion sense and grade level of the Vision in terms of image; the interior also adopts the arch-style family design, benefiting from a unified design language. 2. High configuration and high cost-effectiveness: The car is equipped with automatic headlights, keyless entry, one-button start, reverse camera, and other configurations, as well as automatic folding mirrors, ESC (standard for automatic transmission), tire pressure monitoring, driving recorder, one-button window control for all four doors, in-car connectivity system, "Hello, Vision" in-car voice system, etc. These configurations are very practical. The new Vision also keeps up with the times by adding voice control functions, which are different from simple actions like navigation and song switching, and can even control manual air conditioning. 3. Insufficient seating space: Although the wheelbase of the new Vision has been increased by 15mm, due to the relatively old platform, it is still obvious that the space is half a level smaller than the new Emgrand. When sitting in the back row, you can clearly feel some tightness in terms of seating space.

At What Level of Darkness Should Engine Oil Be Replaced?

The replacement interval for engine oil depends on the type of oil used in the vehicle. Generally, full synthetic oil should be replaced every 10,000 kilometers or once a year. Semi-synthetic oil should be replaced every 7,500 kilometers or every 7-8 months. Mineral oil should be replaced every 5,000 kilometers or every 6 months. If the oil turns black, feels gritty when rubbed between fingers, has poor viscosity, or even feels rough, it should be replaced. Below are the functions of engine oil: 1. Friction reduction: A sufficiently thick oil film separates the surfaces of relatively sliding parts, thereby reducing wear. 2. Sealing: Engine oil can form a seal between the piston rings and the piston, reducing gas leakage and preventing contaminants from entering. 3. Rust prevention: Lubricating oil adheres to the surface of parts, preventing contact with water, air, acidic substances, and harmful gases. 4. Cushioning: When the pressure in the engine cylinder rises sharply, suddenly increasing the load on the piston, piston skirt, connecting rod, and crankshaft bearings, this load is transmitted and lubricated through the bearings, cushioning the impact load. 5. Cleaning: High-quality engine oil can carry carbon deposits, sludge, and worn metal particles from engine parts back to the oil pan through circulation, flushing away dirt generated on the working surfaces of the parts via the flow of the lubricating oil.

How Long Does It Usually Take to Get a Driver's License in Guangzhou?

In Guangzhou, it generally takes 6 months to a year to obtain a driver's license. The specific details are as follows: In Guangzhou, even if you pass all the driving test subjects at once, it usually takes at least over a year to get the license, though some driving schools may be faster. Learning to drive in Guangzhou is different from other places. Here, you must take each subject one by one, and you can only register for the next subject after passing the previous one. The key factor is the number of students enrolled in your driving school—if there are many, the waiting time can be quite long. If you fail any subject, you'll have to wait another month. The process of learning to drive in Guangzhou: 1. Subject 1 Test: From registration to taking Subject 1, the waiting time alone can be lengthy, usually 2 to 3 months. However, the pass rate is high, and the difficulty is low, as it mainly involves theoretical knowledge. 2. From Subject 1 to Subject 2: Typically, you'll have to wait in line for 4 to 5 months, and sometimes even half a year. During this period, you must practice your driving skills diligently; otherwise, if you fail the test, you'll have to wait another month or so. 3. Subject 3: After passing Subject 2, you'll usually wait another 3 to 4 months. During this time, the driving school will arrange a long-distance driving session and charge an additional fee for it. 4. The final subject, the Civilized Driving Test: You'll need to wait at least another month. After registration, if you don't have time to practice all at once, your enrollment remains valid for two years.
