What does 14x2.125 tire mean?

In a 14x2.125 tire, the 14 refers to the tire width of 14 inches, and 2.125 refers to the inner diameter of the tire being 2.125 inches. 14x2.125 is the tire's specification model. The functions of a tire include transmitting driving force, braking force, and steering force to enable vehicle operation; supporting vehicle loads; and reducing and absorbing vibrations and impact forces during driving to prevent severe vibrations from damaging vehicle components. Tire usage precautions are as follows: Tire wear: Worn tire treads can cause loss of grip, affect handling, increase the risk of blowouts, and reduce the tire's ability to expel dirt and water. Tire pressure: Keep a tire pressure gauge handy to check tire pressure regularly. Remove debris from treads: Promptly remove foreign objects from tires to prevent stubborn stones from getting stuck in the treads. When tires wear down to a certain extent, these objects can puncture the tire, leading to leaks or blowouts. Tire rotation: Rotate tire positions every 10,000 kilometers to evenly distribute wear and fatigue, prolonging tire life. In addition to the model, tires are marked with the following common data: Tire cord material: Indicated by Chinese pinyin, such as M-cotton cord, R-rayon cord, N-nylon cord, G-steel cord, ZG-steel radial cord. Speed rating: Indicates the maximum speed a tire can carry a specified load under defined conditions. Letters A to Z represent certified speed ratings from 4.8 km/h to 300 km/h. Common speed ratings include: Q: 160 km/h; H: 210 km/h; V: 240 km/h; W: 270 km/h; Y: 300 km/h. Rim specification: Indicates the rim size compatible with the tire for practical use, e.g., standard rim 5.00F.

Does Emergency Braking Affect the Car?

Occasional emergency braking does not cause significant damage to the vehicle, but frequent emergency braking can have negative effects. The main hazards of long-term emergency braking include: reduced tire lifespan and increased wear; decreased engine lifespan; shortened clutch system lifespan; increased fuel consumption; accelerated wear of brake pads and discs; and hastened aging of brake calipers and master cylinders. Additional information: 1. Braking System: The automotive braking system refers to a series of specialized devices that apply force to certain parts of the vehicle (primarily the wheels) to achieve controlled deceleration. Its functions are: to enable moving vehicles to decelerate or stop as required by the driver; to keep parked vehicles stationary under various road conditions (including on slopes); and to maintain stable speed control for vehicles descending hills. 2. Brake Pads: Also known as brake linings, these are friction materials fixed to rotating brake drums or discs. The friction linings and blocks withstand external pressure to generate friction, thereby achieving vehicle deceleration.

What Causes the Magotan to Always Lack Coolant?

Damage to the radiator and poor sealing of the upper and lower water chambers can lead to coolant leakage; loose connections at the overflow tank, water pump mating surfaces, and various coolant system pipe fittings, along with poor sealing, are the main reasons why the Magotan frequently lacks coolant. Methods to determine if coolant is lacking: Observe the coolant warning light on the dashboard. If it lights up, it is likely due to a lack of coolant, although it could also be caused by excessively high cylinder temperatures. Check the coolant reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving and add coolant promptly. Inspect the water level markings on the coolant tank. The normal coolant level should be between the maximum and minimum marks. Whether coolant is lacking depends on these marks. If the coolant level is below the minimum mark, it indicates a lack of coolant.

What does the brake pedal mean?

The brake pedal is the pedal that restricts power, also known as the foot brake pedal. There are three types of braking systems: 1. Foot brake: The most commonly used brake while driving is operated by the foot, hence it is also called the foot brake. When the driver presses the brake pedal, the braking force is transmitted mechanically or hydraulically to the wheel's braking device to generate friction. 2. Parking brake: Also known as the hand brake, it is a braking device used to prevent the vehicle from slipping when parked. There are generally two types: the intermediate braking type installed on the drive shaft and the direct control rear wheel braking type. 3. Anti-lock braking system (ABS): When driving on slippery or icy low-friction roads, excessive braking can occur, causing the wheels to lock up and lose traction, leading to a loss of control over the vehicle's direction. To enable effective control of the vehicle's direction on such hazardous roads, the ABS (Anti-lock Braking System) was developed.

How Many Liters of Transmission Fluid Should Be Added at Once?

Gravity oil change requires 3~4L of fluid, while a machine flush requires 12L. Below are specific details about automotive transmissions: 1. Definition: A transmission is a gearbox that alters the gear ratio and direction of motion. It is located between the clutch and the central drive. 2. Function: Under constant engine speed and torque, it changes the vehicle's driving force and speed (shifting); allows the vehicle to move in reverse (direction change); and enables the engine to idle without stalling (neutral gear). 3. Transmission Types: Gear-type transmissions can be categorized into three types: dual-shaft, triple-shaft, and compound. Dual-shaft transmissions have two main shafts (excluding the reverse shaft) and achieve speed reduction through a single pair of gears. Triple-shaft transmissions have three main shafts (input shaft, countershaft, and output shaft) and achieve speed reduction through two pairs of gears. Compound transmissions consist of two gearboxes connected in series or parallel to obtain more gear ratios with fewer gears.

What to Do If the New Car Shows 200 Kilometers on the Odometer at Delivery?

If the odometer of a new car shows 200 kilometers, the car might have been a display vehicle or transferred from another location, and you can request a return. Normally, the mileage of a new car at delivery should be between 10 and 50 kilometers. Here are some related details: 1. Testing: After coming off the production line, new cars undergo various tests and are driven onto and off transport trucks during shipping, so it's impossible for a new car to have 0 kilometers. If a new car shows 0 kilometers, the odometer might have been tampered with by the dealership. 2. Tire hairs: New car tires usually have many tire hairs. If the car has been driven for several hundred kilometers, the number of tire hairs will change. Some dealerships may transfer cars from other locations if they don't have stock on hand, and employees may drive the car back directly during the transfer.

How Long Between Subject 2 and Subject 3?

For applying for a C1 driver's license, there must be a minimum interval of 20 days after passing the Subject 2 test before you can schedule the Subject 3 test. For a C2 driver's license, the interval is only 10 days after passing Subject 2. Overview of Subject 3: Subject 3 includes the road driving skills test and the safety and civilized driving knowledge test. It is part of the motor vehicle driver's license assessment and is the abbreviation for the road driving skills and safety and civilized driving knowledge test in the motor vehicle driver's test. The content of the road driving skills test varies depending on the type of vehicle you are licensed to drive. Regulations for Scheduling Subject 3: For the Subject 3 road driving skills test, you have five opportunities to schedule the test. After scheduling, you can take the test once and have one retest opportunity. If you do not take the retest or fail the retest, you must reschedule the test.
