Car tire sidewall small cracks are caused by: 1. Natural aging of the tire; 2. Impact damage to the tire. Precautions for using car tires include: 1. When inflating tires, reduce the tire temperature to normal levels to avoid affecting pressure judgment; 2. Inflate to approximately 2.5bar; 3. Regularly check the wear level of car tires; 4. Avoid exposing tires to high temperatures and direct sunlight. Conditions requiring tire replacement due to cracks: 1. Cracks appear on the sidewall; 2. Cracks are too long or deep, reaching the tread wear indicator depth of 1.6mm; 3. Tire bulging occurs; 4. Wavy cracks on the tire surface; 5. Visible scratches or punctures on the tire surface.

Are Tengsen Tires Semi-Slick?

Tengsen tires are not semi-slick tires. Here is an introduction to semi-slick tires: 1. Semi-slick tires refer to more sport-oriented products compared to regular tires, featuring a tread that softens and becomes highly adhesive at operating temperatures, thereby enhancing grip. 2. Their lower weight and reduced aspect ratio improve wheel responsiveness and tire contact area, while stiffer sidewalls minimize deformation during aggressive driving. Fewer tread blocks and reduced tread patterns directly increase the tire's contact area with the ground. 3. These tires incorporate high-tech materials like Kevlar fiber (the primary material in modern bulletproof vests) during manufacturing, strengthening the sidewalls while reducing weight and improving tire support. 4. Compared to regular tires, their more advanced tread design reduces tread patterns while maintaining comparable water dispersion. Larger tread blocks increase the actual contact area between the tread and the road during driving, reducing tread deformation. Combined with stiffer sidewalls and a lower aspect ratio, this allows drivers to receive road feedback more directly and swiftly, enhancing control precision.

Can a motor vehicle still undergo annual inspection if it's overdue by 2 months?

Motor vehicles can still undergo annual inspection even if it's overdue by 2 months. Handling methods for overdue vehicle annual inspection: 1. The vehicle owner or unit must fill out the "Motor Vehicle Annual Inspection Form" and send the vehicle to the designated location for inspection on the date specified by the local vehicle management office. After the vehicle passes inspection, the vehicle management authority will affix an inspection approval seal on the vehicle's license and the "Motor Vehicle Annual Inspection Form". 2. For vehicles that cannot undergo inspection on time due to long-term assignments in other locations, the owner must submit an application and report to the original vehicle management office for authorization to have the inspection conducted by the local vehicle management office. After inspection, the results will be notified to the original vehicle management office. 3. Vehicles that cannot undergo annual inspection on time due to special circumstances should apply for an extension in advance with the local vehicle management office.

What is the solution for a motorcycle clutch not disengaging?

Here is a detailed introduction to the solutions for a motorcycle clutch not disengaging: 1. Adjust the free play of the clutch disengagement mechanism: If the clutch lever is pulled all the way in and the clutch still does not fully disengage, adjust the clutch disengagement mechanism to set the free play between 4mm~8mm. When the clutch is fully engaged, it should shift smoothly, and during startup, there should be no knocking in the transmission or sudden jerking forward of the vehicle, and the engine should not stall. If everything is normal, the adjustment is correct. 2. Check the engine oil: If the problem persists after adjustment, check the engine lubricating oil. Start the engine, and after the vehicle warms up or is driven, if the situation improves significantly, it is mainly due to the lubricating oil. Simply drain the existing lubricating oil after the vehicle warms up and refill it with the appropriate lubricating oil for the vehicle, and the issue should be resolved.

What does 'man' mean in car air conditioning?

Air conditioning 'man' refers to the air circulation mode inside the car. 'Man' means the fixed internal circulation mode. When the internal circulation light is off, it indicates the external circulation mode. If the air inside the car becomes stale, you can turn on the external circulation function because it serves the purpose of ventilation. Here is additional information about air conditioning circulation modes: 1. 'Auto' automatically determines whether internal or external circulation mode is needed based on the air quality outside the car. 'Auto' means automatic. Car air conditioning cooling is divided into internal and external circulation modes. The internal circulation mode provides better cooling efficiency, but prolonged use can degrade the air quality inside the car. If the air inside becomes stale, you can turn on the external circulation function, as it facilitates ventilation. Setting the air conditioning to 'auto' enables automatic switching between circulation modes. 2. 'Man' is the fixed internal circulation mode. Press and hold the 'man' button on the right side until the indicator light flashes three times and stays lit, which forces the system into internal circulation mode.

What Causes a Truck to Pull to One Side?

Here are the specific reasons for a vehicle pulling to one side: 1. Changes in wheel alignment data: Variations in wheel alignment data can cause the vehicle to pull to one side, especially for vehicles frequently driven on rough roads, as wheel alignment parameters are prone to change. The vehicle pulling to one side is mainly related to the front wheel camber angle. If the camber angles of the two front wheels are inconsistent, the vehicle will pull towards the side with the larger camber angle. 2. Abnormalities in the vehicle's steering system: For example, bending or deformation of the steering knuckle arm or steering knuckle can generally cause the vehicle to pull to one side. The most severe issue is severe wear and loosening of the tie rod ends, which can lead to steering failure, causing the vehicle to lose control completely. 3. Faults in the suspension system: If the front shock absorber springs are deformed or one side fails, it can result in uneven suspension height, leading to uneven force distribution and causing the vehicle to pull to one side.

What are the reasons for a car being locked?

Locked cars are vehicles that cannot be transferred or sold. Below are the relevant explanations: 1. Installment payment: For cars purchased through installment payments, if the bank payments are in arrears, the bank may apply to the court for debt collection. The court will then issue a seizure notice to the vehicle management office, prohibiting all operations such as inspections. 2. Full payment: The second scenario involves fully paid cars where the owner has outstanding debts. Creditors may apply to the court to first seize and lock the vehicle, then determine its ownership through a judgment. 3. Illegal use: Lastly, if criminals use the vehicle for illegal activities or purchase it with illicit funds, the public security bureau may seize the vehicle to recover it, prohibiting all operations such as inspections and transfers. A locked vehicle's records have no usage rights or significance, meaning the vehicle cannot be used. If the disputes involving the seized vehicle are not resolved within the specified period, the vehicle may be locked at any time, rendering it unfit for road use.
