What is the difference between 99H and 99V tires?

The primary difference between the two tires lies in their maximum speed tolerance. The speed rating indicates the highest speed a tire can achieve under specified load and inflation pressure conditions. V and H represent speed ratings, with V designed for a maximum speed of 240 km/h and H for 210 km/h. The number 99 is the load index, indicating the tire's maximum load capacity of 775 kg. Common vehicle models in the market mostly use H and V-rated tires, while some high-performance vehicles utilize W and Y-rated tires. Tire specifications are data that indicate the geometric parameters and physical performance of tires. There are three methods to represent tire specifications: A. Metric (m); B. Mixed metric-imperial; C. Imperial. Imperial tire specifications are typically denoted by a set of numbers, where the first number represents the tire section width, and the second number indicates the rim diameter, both in inches. The most common markings on tires are the tire brand, followed by the tire specifications, and then the load index and speed rating. The speed rating is the maximum speed limit determined during the design and production of the tire after considering various factors and testing. Exceeding this speed can lead to multiple safety hazards. Generally, all-terrain tires (AT) have lower speed ratings compared to highway tires to account for their performance on unpaved roads. Load index and inflation pressure. These typically indicate the maximum load and corresponding pressure, with the load measured in "kilograms" and the pressure (tire inflation) in "kilopascals." The wear limit of the tire is marked on one side with rubber strips or blocks. When the tire wear approaches about 4mm from this limit, replacement should be considered. The so-called three "T" indicators, often seen together on the tire sidewall, are Treadwear (wear resistance), Traction (traction performance), and Temperature (temperature resistance). These three indicators, in addition to conventional parameters like size, speed rating, and load rating, allow consumers to make informed choices about tires, though they are not widely known. Besides the model, tires also bear 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 at which the tire can carry a specified load under defined conditions. Letters A to Z represent certified speed ratings ranging from 4.8 km/h to 300 km/h. Commonly used 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.

Is it acceptable to use parking lights when entering a tunnel?

Short tunnels are acceptable, but it is recommended to use low beams in long tunnels. Here is relevant information about the use of automotive lights: 1. Parking lights usage: Parking lights are white in front and red in the rear. When the light switch is turned to the first position, the front and rear lights that come on are the parking lights. Parking lights are used during evening driving to make the vehicle visible to others. When it becomes difficult to see behind through the rearview mirror, the parking lights should be turned on, especially during rainy days. However, many drivers use parking lights instead of low beams when driving in the dark, which is very dangerous because parking lights do not illuminate the road ahead. 2. Low beam usage: Low beams must be turned on when driving in areas without streetlights at night, during dusk when it is darker, or at dawn when daylight is just appearing. If encountering heavy fog, snow, or heavy rain that obstructs visibility, low beams must be turned on even during the day. In some areas where there is lighting but the brightness is insufficient, low beams should also be used. 3. High beam usage: High beams should only be used when there are no other lighting facilities on the road and no oncoming vehicles. Otherwise, they can severely interfere with the vision of other drivers and even cause traffic accidents. Be careful not to mistakenly use high beams instead of low beams.

What Happens When a Stationary Car Gets Flooded?

A stationary car that gets flooded can cause the following damages: 1. Pungent odor inside the car: A water-damaged car will have a musty and foul smell, which is very difficult to eliminate completely. 2. Rusting of interior brackets: There are many exposed metal brackets under the dashboard. Since these brackets are not easily exposed to moisture, manufacturers typically do not apply anti-rust treatment to them. When water enters the car and evaporates, it causes these brackets to rust. 3. Hardened seats: For cars where the water level reaches the seats, even after cleaning and drying, the seats will feel stiff, more like sitting on thick cardboard rather than foam. Pressing them with your hand will also reveal a lack of elasticity. 4. Rusting of wheel bearings: If the car is submerged in water for a long time, water molecules can penetrate the bearings, causing the grease to deteriorate and leading to rust. This results in noticeable abnormal noises when the wheels rotate.

What does the fuel-saving switch 1/2 and 1 mean?

The fuel-saving switch is named "Engine Multi-state Torque Switch". Its function is to adjust the engine's output power, providing lower power when the vehicle is empty to achieve fuel-saving purposes, while delivering full power when heavily loaded to meet the vehicle's rigid demand for performance. 1/2 indicates use during medium load, and 1 indicates use during heavy load, corresponding to different operating conditions. Below is some information about fuel consumption: 1. Introduction: Generally refers to the amount of gasoline consumed per 100 kilometers, which is a theoretical indicator of the vehicle. 2. Methods to reduce fuel consumption: The longer the idle time when parked, the greater the fuel consumption, so try to minimize idle parking time; avoid rapid acceleration, slamming the throttle, and driving at lower RPMs. 3. Factors affecting fuel consumption: Various working conditions such as acceleration, deceleration, braking, and engine idling, as well as load capacity, temperature, and whether the air conditioning is on, all have an impact.

Where is the Low Beam Located?

The switch for the low beam is generally located on the left side of the dashboard, near the door. Turning it one notch activates the low beam. The smaller bulb on the inner side of the front of the car is the high beam, while the larger lamp on the outer side is the low beam. Below are specific details about the low beam of motor vehicles: 1. Usage: The high beam is typically used when driving at night on roads without streetlights or with poor lighting, such as on dimly lit national highways or expressways. In urban areas with good lighting, the low beam must be used. 2. Related lighting change regulations: When passing under an arch bridge or a crosswalk at night, alternate between low and high beams; when passing through an intersection without traffic signals at night, alternate between low and high beams; when navigating sharp curves or slopes at night, flash the low and high beams alternately twice consecutively.

Does touching the line in the S-curve during Subject 2 result in failure?

S-curve line touching is considered a failure. According to Subject 2 examination deduction code 20601: During curve driving, if the vehicle's wheels touch the road edge line, 100 points will be deducted. Below are some introductions about the S-curve: 1. Precautions: Use the rearview mirror to observe the rear, steer towards the side where the rear of the car is wider, avoid reversing too quickly, and make corrections promptly. 2. Principle: Steering follows the rule of 'steer as much as you return, steer fast return fast, steer slow return slow'. For example, if the left rear of the car is wider, steer 90 degrees to the left. When approaching the desired effect, return 90 degrees to the right. The same principle applies to the speed of steering.
