What is Yokohama Tire?

Yokohama, known in Chinese as Yokohama Tire (formerly called Yokohama Tire), is a brand of tires. The main models of Yokohama tires include 195/65R15 and 205/60R15. Tires are one of the essential components of a vehicle, directly contacting the road surface and working in conjunction with the vehicle's suspension to absorb shocks during driving, ensuring a comfortable ride and smooth driving experience. Tires are circular elastic rubber products mounted on various vehicles or machinery that roll on the ground. They are often used under complex and demanding conditions, enduring various deformations, loads, forces, and extreme temperatures during operation. Therefore, tires must possess high load-bearing capacity, traction performance, and cushioning ability, along with high wear resistance and flexibility, as well as low rolling resistance and heat generation.

What does parking brake mean?

Parking brake refers to the manual brake installed in motor vehicles, commonly known as the handbrake. It is used to stabilize the vehicle after it comes to a stop, preventing accidents caused by rolling on inclined roads. The typical handbrake is usually positioned within easy reach of the driver's right hand for convenient operation. Some automatic transmission models on the market feature a foot brake located outside the driver's left foot, which serves the same function as the handbrake. Advanced models may also be equipped with an electronic parking brake system. Functions of the parking brake: Prevent the vehicle from rolling after stopping, assist in smooth starting on slopes, and serve as a temporary or supplementary emergency brake when the service brake fails. Under normal circumstances, the parking brake should not be used to slow down the vehicle before it comes to a complete stop. In all cases when parking, the driver must firmly pull the parking brake lever before leaving the vehicle. How to use the parking brake: To engage the parking brake, press the brake pedal down and pull the parking brake lever up fully. To release the parking brake, press the brake pedal down, slightly lift the parking brake lever, press the button on the handle with your thumb, and then lower the parking brake lever back to its original position.

How to Coordinate the Clutch and Throttle When Shifting Gears in a Manual Transmission?

Manual transmission shifting clutch and throttle coordination method: First, place the gear in the neutral position, start the car and press the clutch pedal all the way down, then shift the gear into the 1st gear position. After that, slowly release the clutch. When you feel the car slightly vibrate and start to move forward, gradually press the throttle while continuing to release the clutch until it is completely released, ensuring the car starts smoothly. During normal driving, the left foot should rest on the car floor, not on the clutch pedal. This is because while driving, if the left foot is placed on the clutch, the inertia will exert pressure on the clutch, accelerating its wear.

What are the advantages and disadvantages of rear-wheel drive vehicles?

The advantages of rear-wheel drive vehicles are: 1. Better handling feel with more balanced weight distribution between the front and rear wheels; 2. Smaller turning radius, making U-turns more efficient; 3. Increased traction, improving acceleration; 4. Easier maintenance. The disadvantages are: 1. Rear-wheel drive vehicles are prone to oversteering; 2. In rainy or snowy conditions, improper steering can easily cause the vehicle to spin in place. Rear-wheel drive means that the engine's power is transmitted to the rear wheels via the driveshaft, propelling the vehicle forward. This is a relatively traditional drive form, as most early cars were rear-wheel drive. Examples of rear-wheel drive vehicles include the Cadillac ATS-L, Infiniti Q50L, and Jaguar XEL.

What documents are needed for new car registration?

Documents required for new car registration include: ID card, vehicle certificate of conformity, triplicate car purchase invoice issued by the 4S store, original and duplicate tax certificates obtained after paying the vehicle purchase tax, insurance policy, compulsory traffic insurance policy, and temporary residence permit if you are not a local resident. New car registration needs to be processed at the vehicle management office. After submitting all the required documents and paying the fees, the vehicle must be driven to the vehicle management office for inspection. Some vehicles that are exempt from inspection only need an external inspection, which generally involves checking the engine number and chassis number. After the inspection, you can go to the vehicle management office hall to select a license plate. The license plate is the numbering and information registration for each vehicle. Its main function is to identify the region to which the vehicle belongs and to trace the owner and registration information of the vehicle based on the license plate.

What Causes Heavy Steering Wheel?

Heavy steering wheel can be caused by: 1. Electronic power steering failure: A diagnostic scanner is needed to read the specific fault code, and then analyze the cause based on the code; 2. Hydraulic power steering failure: Check if the power steering fluid is low or if the power steering pump is damaged; 3. Steering gear failure: This issue rarely occurs in new vehicles but may occasionally happen in older cars; 4. Check tire pressure: A flat tire can also make the steering heavier, requiring inflation. The steering wheel is typically connected to the steering shaft via splines, converting the force applied by the driver on the wheel's edge into torque transmitted to the steering shaft. A larger-diameter steering wheel requires less hand force from the driver. The steering intermediate shaft, acting as a connector between the steering gear and steering shaft, facilitates the standardization of steering gears, compensates for manufacturing and installation errors, and optimizes the installation of the steering gear and steering wheel in the vehicle.
