Why is there still a clicking sound when there are no stones in the tires?

How many kilometers should car tires be rotated front to back?

1.5 to 20,000 kilometers is the recommended interval for rotation. Below is extended information about tire rotation: 1. When rotating front and rear tires, you cannot swap them randomly. Symmetrical tread patterns can be cross-rotated, while asymmetric and unidirectional tread patterns must be rotated front-to-back only. If the tire wear appears particularly severe, replacement is recommended. 2. Cars are categorized as front-wheel drive, rear-wheel drive, and four-wheel drive. During driving, the force distribution on the tires varies. For four-wheel drive vehicles, if the front tires are excessively worn, they can be directly swapped with the rear wheels. However, for front-wheel drive vehicles, the front tires experience more stress due to frequent turning, acceleration, and braking during daily driving, leading to greater wear compared to the rear tires. Therefore, when installing new tires, a diagonal rotation method can be used. Of course, during tire rotation, the degree of wear should be checked. If the wear is significant, rotation should be avoided, and new tires should be installed instead.

What is the Difference Between Engine Oil and Transmission Oil?

Engine oil and transmission oil differ in viscosity and the temperatures they can withstand. Engine oil is used for the normal operation of the engine, enduring the highest temperatures and having the lowest viscosity. Transmission oil is used for the transmission, enduring lower temperatures and having a higher viscosity than engine oil. Details about engine oil and transmission oil are as follows: 1. The main function of automotive transmission oil is to keep the gear shift system clean, providing lubrication and cooling. During driving, the gears operate at high speeds, generating heat through friction, which necessitates the use of gear oil for lubrication and temperature reduction to ensure the vehicle's normal operation. 2. The primary function of engine oil is to lubricate the engine system, providing lubrication, cooling, sealing to prevent leaks, rust and corrosion prevention, as well as shock absorption. It can be said that the condition of the engine oil directly affects the performance and lifespan of the engine, making it a crucial automotive consumable.

Does the ABS self-check make noise every time you start the car?

The sound of the ABS system self-check cannot be eliminated. This is a normal sound, as it pumps oil every time it operates, and this cannot be removed. Relevant details are as follows: 1. ABS: ABS (Anti-lock Braking System) prevents wheel lock-up by using sensors installed on the wheels to detect when a wheel is about to lock. The controller then instructs the regulator to reduce the hydraulic pressure in that wheel's brake cylinder, decreasing the braking torque. After a short period, the original hydraulic pressure is restored. This cycle repeats (up to 5~10 times per second), ensuring the wheels remain rotating while maintaining maximum braking torque. 2. Skidding: In cars without ABS, if the brake pedal is pressed hard while driving, the wheel speed rapidly decreases. When the braking force exceeds the friction between the wheel and the ground, the wheel locks up. A fully locked wheel reduces the friction between the tire and the road. If the front wheels lock, the driver loses control of the vehicle's direction. If the rear wheels lock, skidding is highly likely to occur.

How to Calculate the Purchase Tax for an 80,000 RMB Car?

The purchase tax for cars with an engine displacement of 1.6 liters or below = the tax-inclusive price of the car on the invoice / 1.17 * 7.5%. Here are the detailed explanations: 1. Explanation one: From January 1, 2017, to December 31, 2017, a 7.5% vehicle purchase tax rate was applied to passenger cars with a displacement of 1.6 liters or below. 2. Explanation two: The vehicle purchase tax is a tax levied on units and individuals who purchase specified vehicles within China, evolving from the vehicle purchase surcharge. The current basic regulation of the vehicle purchase tax law is the "Interim Regulations of the People's Republic of China on Vehicle Purchase Tax," implemented from January 1, 2001.

How many points will be deducted for overloading a 7-seater minibus with 2 extra passengers?

Overloading a 7-seater minibus with 2 extra passengers will result in a 3-point deduction. Here are the detailed regulations: 1. Regulation 1: Driving an operational passenger vehicle (excluding buses) or school bus with over 20% more passengers than the approved capacity will result in a 12-point deduction. 2. Regulation 2: Driving a passenger vehicle other than an operational passenger vehicle (excluding buses) or school bus with passengers exceeding the approved capacity by less than 20% will result in a 3-point deduction. 3. Regulation 3: Driving an operational passenger vehicle (excluding buses) or school bus with passengers exceeding the approved capacity by less than 20%, or driving other passenger vehicles with over 20% more passengers than the approved capacity, will result in a 6-point deduction.
