What do the three T indices on tires represent?

Tire 3T indices refer to treadwear index, traction index, and temperature index. Below is relevant information about tires: 1. Functions of tires: Mainly include dry traction, hydroplaning resistance, providing comfort, reducing driving noise, impact resistance, wet traction, load capacity, handling performance, average wear, and mileage. 2. Tire cross-section structure: Can be broadly divided into 4 parts: tread, shoulder, sidewall, and bead. Each part has its own function. The tread primarily contacts the ground, the shoulder and sidewall provide support, and the bead contacts the wheel rim to create a seal. 3. Internal composition of tires: Consists of multiple layers of different materials stacked together, including tread pattern, cap ply, steel belt, stress absorption rubber strip, carcass ply, and inner liner.

What Causes Water Dripping Under the Car in Summer?

Dripping water under the car in summer is a normal phenomenon due to the complete combustion of fuel in the engine. Below are the specific reasons for water leakage under the car: 1. Evaporator drainage: The car's air conditioning system is equipped with an evaporator inside the dashboard. When the air conditioning is turned on (A/C button ON), the surface temperature of the evaporator becomes very low, causing moisture in the hot air inside the car to condense on the heat-absorbing fins of the evaporator. The condensed water is collected by the plastic housing of the evaporator and drained out of the car through a pipe. 2. Uninsulated low-pressure pipes: If the low-pressure pipes are not wrapped with insulation foam, the surface of the pipes can easily condense moisture from the air, causing water droplets to form and drip from the lowest point of the pipes.

What to do if driving at 115 in a 100 speed limit zone?

On highways with a speed limit of 100, driving at 115 km/h exceeds the speed limit by more than 10% but less than 20% according to traffic laws, resulting in 3 demerit points on the driver's license. Below are the hazards of speeding: 1. Vehicle steering becomes unstable: Speeding increases the airflow speed difference between the top and bottom of the vehicle body. This differential causes the vehicle to generate upward lift, reducing stability during driving, which is a major reason for unstable steering. 2. Driving habits intensify: The faster the speed, the stronger the vehicle's inertia to maintain straight-line driving, leading to poorer steering control and significantly increased risks. If an emergency occurs ahead, it becomes difficult to control the vehicle within a short time, potentially causing unimaginable consequences.

What does the yellow P light with a slash mean?

On the car dashboard, the yellow P light with a slash indicates that the parking brake is engaged, meaning the handbrake is in the braking position and not fully released. If the handbrake has been completely released, then it signifies a warning for a potential brake system malfunction. It is recommended to check if there are any issues with the handbrake, whether the brake fluid is low, if the handbrake is fully disengaged, and if the handbrake cable connections are normal. Below is additional information: 1. Parking brake malfunction: Drive with caution and have it inspected and repaired at a service center as soon as possible. 2. Reasons for the parking brake warning light to illuminate: Lack of brake fluid, which is an essential part of the car's braking system. When the driver presses the brake pedal, the force applied is transmitted by the master cylinder piston through the brake fluid to the wheel brake cylinders, causing the brake pads to contact the wheels and stop the vehicle.

How many points are deducted for rear-end collision due to failure to maintain a safe distance?

Rear-end collision due to failure to maintain a safe distance results in a deduction of 3 points. Below are precautions to avoid rear-end collisions: 1. Alert the following vehicle: If you notice the following vehicle is too close, you can lightly tap the brakes to remind them to maintain a safe distance. Turning on the rear fog lights can also serve as a warning function to prevent being rear-ended. 2. Do not follow too closely: Whether it's the distance in front or behind, it should be kept within a safe range. Check the rearview mirror to confirm the position and distance of the following vehicle. If you notice any abnormal movement trajectory of the following vehicle or the presence of a large truck, you should pull over to avoid potential danger. 3. Learn to use intermittent braking: When braking, avoid slamming on the brakes abruptly. Instead, try to use intermittent braking as much as possible. This provides the following vehicle with reaction time and buffer distance, thereby reducing the likelihood of a rear-end collision.

What are the benefits of a dual-clutch transmission?

The advantage of a dual-clutch transmission is fast acceleration and fuel efficiency. DSG (Direct-Shift Gearbox) is a transmission commonly used by Volkswagen. Here is a detailed introduction to the dual-clutch transmission: 1. Principle: A dual-clutch transmission has two clutches. Clutch I is responsible for 1st, 3rd, 5th gears, and reverse, while Clutch II is responsible for 2nd, 4th, and 6th gears. Simply put, in automatic mode, when starting in 1st gear, Clutch II is already prepared to shift to 2nd gear. When the car reaches a certain RPM, Clutch II shifts to 2nd gear, and Clutch I prepares for 3rd gear, and so on. The entire shifting process takes less than 0.2 seconds, making it faster than manual shifting. In manual mode, it can also perform skip-shifting. 2. Advantages: Conventional automatic transmissions have a torque converter with hydraulic transmission, which causes some power loss during acceleration, though this disappears at higher speeds. However, the DSG transmission is fully engaged, ensuring no power loss whether during acceleration or at high speeds. That said, dual-clutch transmissions are more technologically advanced, so maintenance costs are significantly higher than those of conventional transmissions.
