What is the validity period for driver's license renewal?

The renewal period for a driver's license is divided into three time frames: 6 years, 10 years, and permanent. Normally, the initial driver's license is valid for 6 years. After 6 years, it can be renewed to a 10-year validity license, and after 10 years, it can be renewed to a permanent license. Things to note when your driver's license expires: 1. Renewal time: You can apply for a new license up to 90 days before the expiration date at the vehicle management office where the license was originally issued. 2. Expired for 1 year: If you fail to renew your license on time, you can still apply for a new one within 12 months after expiration, provided you have not driven a motor vehicle during this period. Otherwise, you will be penalized for driving without a license, facing a fine of around 2000 yuan and 15 days of detention. 3. Expired for 3 years: If your license has been expired for more than 12 months but less than 36 months, you will need to retake the subject one exam to renew your license. Driving during this period is also prohibited. 4. Expired for more than 3 years: If your license has been expired for more than 36 months, it will be revoked, and you will need to reapply for a new driver's license from scratch.

Should You Replace the Tire If the Shoulder Is Punctured by a Nail?

If the tire shoulder is punctured by a nail, it's better to replace the tire directly rather than repairing it. This area is constantly squeezed and deformed during driving as it comes into contact with the ground, so even if repaired, it may not last long before leaking air again. Therefore, if the tire shoulder is punctured, it's best to replace the tire outright and avoid further repair attempts. More relevant information is as follows: 1. The tire is the only part of the vehicle that comes into contact with the ground, directly affecting the driving stability and safety of the vehicle. If the puncture occurs in the tread area (the part that contacts the ground), it can still be repaired. However, if the sidewall is punctured, it is strongly recommended not to repair it. 2. Modern car tires are mostly radial tires, primarily composed of the carcass ply and rubber. The carcass ply consists of crisscrossing cords (some also include steel wire mesh), which mainly bear the load, while the rubber provides sealing and flexible deformation functions. 3. When a tire is punctured and leaks air, it is mainly due to damage to the inner liner, which can be repaired. However, if the carcass ply is damaged, it directly affects the tire's strength. The more cords that are broken, the greater the risk of a blowout.

Why is the outer side of the front tire severely worn?

It is related to inaccurate four-wheel alignment data. This requires replacing the worn tires and then performing a four-wheel alignment. Some models experience this issue because they only have independent front suspension, while others have independent suspension that cannot be adjusted, requiring professional inspection and repair. Other wear conditions are as follows: 1. Early wear on the central part of the tire (tread crown): The main reason is over-inflation. Properly increasing tire pressure can reduce rolling resistance and save fuel. However, excessive inflation not only affects the tire's shock absorption performance but also causes excessive deformation, reducing the contact area with the ground. As a result, normal wear is concentrated on the central part of the tread, leading to early wear. 2. Excessive wear on both sides of the tire (shoulders): The main reasons are under-inflation or long-term overload driving. When tire pressure is low or the load is heavy, the contact area between the tire and the ground increases, causing both sides of the tire to engage with the ground and leading to early wear. If tire pressure is 20% above or below the rated value, mileage loss can range from 20% to 25%. 3. Excessive wear on one side of the tire: The main reason is inaccurate front-wheel alignment. When the camber angle of the front wheels is too large, the outer side of the tire experiences early wear. Conversely, if the camber angle is too small or absent, the inner side of the tire will show early wear.

What Causes Smoke from the Exhaust Pipe with a Burnt Smell?

White smoke from the exhaust pipe is generally normal, but if it appears in large quantities, it may indicate a faulty engine piston that has started burning oil. As for the smell, it is usually caused by the release of odor from the silicon material inside the catalytic converter when heated, which is also normal. However, if the pungent smell becomes increasingly strong, it is advisable to have it inspected and repaired at a service center. Below is more related information: 1. Normal white smoke: Normal white smoke occurs because the exhaust gases exiting the pipe are at a high temperature, causing the high-temperature water vapor to rapidly condense into tiny droplets in the cooler air, resulting in "white smoke," which is physically known as liquefaction. If there is a large amount of white smoke, it could be due to a damaged engine piston burning oil. 2. Excessive moisture: If there is too much moisture in the gasoline, it is recommended to clean the throttle body. If the gasoline contains water, check for leaks at the junction of the cylinder head and gasket. If leaks are found, it may indicate a damaged cylinder gasket. 3. White smoke in low temperatures: White smoke during cold starts is normal and should disappear as the engine warms up. However, if the smoke increases and persists when accelerating, accompanied by a worsening pungent smell, it is best to have it inspected and repaired at a 4S shop.
