Car tire sidewall punctures cannot be repaired and require tire replacement. Below is relevant information about tires: 1. Tires are one of the most important components of a vehicle, serving several key functions: supporting the entire weight of the vehicle and bearing its load; transmitting traction and braking torque to ensure proper contact between the wheels and the road surface; absorbing shocks and vibrations during driving to prevent excessive vibration and premature damage to vehicle components; adapting to high-speed performance while reducing road noise; and ensuring driving safety, handling stability, comfort, and fuel efficiency. 2. Tires operate under complex and demanding conditions, enduring various deformations, loads, forces, and extreme temperatures during use. Therefore, they must possess high load-bearing capacity, traction performance, and shock absorption capabilities. Additionally, they need excellent wear resistance, flexibility, low rolling resistance, and heat generation properties. Approximately half of the world's rubber consumption is used for tire production, demonstrating the significant demand for rubber in tire manufacturing.

I think this question is too common. As a veteran driver with 30 years of experience, I can definitely tell you that a puncture on the tire sidewall absolutely cannot be repaired. The sidewall is the most fragile part of the entire tire because it lacks the steel belt reinforcement found in the tread and bears the brunt of steering and weight impacts. Any repair attempt can easily lead to a blowout while driving, especially at high speeds or on curves—risks are significantly higher. I personally witnessed a friend's accident after patching a small sidewall puncture, and it was a complete nightmare. Rather than taking risks to save money, it's better to replace it with a new tire early—choose a durable brand for longer lifespan and safety. Remember, taking a few minutes to walk around your car and inspect tire conditions before each drive can prevent many issues. Developing a habit of regularly checking tire pressure is also crucial—don't wait until a major incident occurs to regret it.

How many days are generally required for Subject 2 driving practice?

Subject 2 generally requires 12-22 days of practice. Below are some important notes regarding the Subject 2 test: Complete the test according to the rules: Each test item in the examination area is monitored by GPS positioning. The control line (yellow dotted line) of each item represents the test area for that item. Once the front of the vehicle crosses the control line, it means the test for that item has begun, and the test must be completed according to the rules of that item. Correct mistakes immediately: When an operational error is discovered, it should be corrected promptly to ensure accuracy and reduce the chance of point deductions. For example, one student successfully parked in the parallel parking test but forgot to shift to the forward gear when exiting, causing the car to move slightly before realizing the gear was not engaged.

Will points be deducted for overdue vehicle inspection?

Points will be deducted for overdue vehicle inspection. Here is relevant information about overdue vehicle inspection: Overdue vehicle inspection: Overdue inspection, as the name suggests, refers to being outside the review period. It mainly means that certain certificates or documents that require periodic inspection have not been inspected within the specified time limit. Penalties for overdue vehicle inspection: Within three months, there is no fine. If it exceeds three months but is less than two years, 3 points will be deducted. If it exceeds two years without an annual inspection, the vehicle's file will be canceled. Overdue vehicle inspection can be supplemented, but penalties will be imposed. If a motor vehicle fails to undergo safety technical inspection within the prescribed period, 3 points will be deducted. For annual inspection, bring the vehicle license, copy of compulsory traffic insurance, and proof of completed traffic violations to the local vehicle management office for the annual inspection.

What Causes the Squeaking Noise After Installing New Brake Pads?

After replacing brake pads, the squeaking noise is caused by the initial bedding-in process of the newly installed brake pads. Below are relevant explanations about brake pad noise: Brake pad maintenance guidelines: The first replacement is generally recommended at 60,000-70,000 kilometers. Some vehicles (typically high-end models) have warning lights to indicate when brake pad replacement is needed. Alternatively, when the friction material wears down to the metal indicator line on the brake pad, you'll hear a screeching sound, which means immediate replacement is required. Proper driving techniques: Always maintain full concentration and situational awareness. Anticipate problems early by easing off the accelerator to decelerate, and decide whether to apply brakes based on changing conditions. This approach not only saves fuel but also extends the service life of your brake pads.

Can Subject 4 be taken nationwide?

Yes. For applicants of C1, C2, and C5 driver's licenses, Subject 4 can be taken in a different location. Since June 2019, the Ministry of Public Security has implemented the policy of taking different subjects of the small car driver's license exam in different locations on the basis of the "national unified examination". Exam preparation tips: Master problem-solving techniques: Similar to Subject 1, Subject 4 also has a large number of practice questions, so rote memorization often leads to a vicious cycle of remembering and forgetting, ultimately consuming a lot of time and effort without corresponding results. Conduct regular mock exams: When you have a good grasp of the knowledge, take a mock exam every day to get into the exam mindset early, which can achieve twice the result with half the effort.
