Method to check the date of new car tires: There is a set of 4-digit numbers on the side of the tire, which represents the production date of the tire. The last 2 digits of this set of numbers indicate the year, and the first 2 digits indicate the week of production in that year. Here is a partial introduction about the 3T index of tires: Treadwear Index: TREADWEAR reflects the wear resistance of the tire. The higher the value, the more wear-resistant the tire is, but it also means the tire is harder and less comfortable, and vice versa. Generally, a treadwear index between 280-320 is moderate, theoretically allowing the tire to run about 100,000 kilometers. Traction Index: TRACTION represents the traction index, and the following letters indicate the strength of the traction, ranging from high to low as AA, A, B, and C. Temperature Grade: TEMPERATURE A indicates the temperature grade of the tire. The following letters represent the high-temperature resistance level of the tire, with the levels for passenger car tires ranging from high to low as A, B, and C.

I just bought a new car and was excited to find out how fresh the tires are. Actually, it's quite simple—the tire date is on the DOT code on the sidewall, with the last four digits being the key. For example, ‘3522’ means the first two digits, 35, indicate the 35th week of production, and the last two digits, 22, stand for the year 2022. This means it was manufactured in late August 2022. This date is crucial because tires age over time, and the rubber material hardens, potentially leading to safety hazards while driving. New cars usually come with relatively fresh tires, but it’s best to check all four tires to ensure their dates match, in case some were replaced with older stock. I recommend glancing at this code during every maintenance check and considering other factors to assess tire lifespan. Generally, tires should be replaced every five to six years—don’t just rely on tread depth to judge their condition. The storage environment for new cars also matters, as high temperatures and sun exposure accelerate aging, so parking in a garage can help extend tire life.

How Long Does It Take to Drive 170 Kilometers by Car?

To drive 170 kilometers by car, assuming a highway speed limit of 120 km/h, it would take approximately 1 hour and 25 minutes. Below are some highway driving techniques and precautions: Driving Techniques: Check the rearview mirror when braking, and judge the following distance based on the speed of the vehicle ahead and the start time; maintain a fast and steady driving pace, adjust your mindset, and drive with a calm attitude for stability and safety; know how to use the horn and signals to communicate with vehicles in front and behind. Highway Driving Precautions: When driving on the highway, vehicles must adhere to traffic regulations, with different types of vehicles staying in their respective lanes. Both the driver and front-seat passenger must fasten their seatbelts, ensuring they remain buckled throughout the entire journey. The driver must focus solely on driving—avoid making phone calls, looking at the phone, or using headphones to listen to recordings, as this may prevent hearing other vehicles' horns and lead to dangerous situations.

What is the box behind the exhaust tailpipe?

The box behind the exhaust pipe is the car muffler. The composition structure and working principle of the car muffler are as follows: Composition structure of the car muffler: According to the noise reduction principle and structure, car mufflers can be divided into three types: reactive mufflers, resistive mufflers, and impedance composite mufflers. Reactive mufflers process sound internally through components such as pipes and baffles to form expansion chambers and resonance chambers; resistive mufflers are designed to absorb sound energy by filling the pipes through which exhaust passes with sound-absorbing materials; impedance composite mufflers are a combination of reactive muffler units and sound-absorbing materials. Working principle of the car muffler: The difference in length between the two pipes of the car muffler is equal to half the wavelength of the sound wave emitted by the car, causing the two sound waves to interfere and cancel each other out when superimposed, thereby reducing the sound intensity and achieving the noise reduction effect.

What are the reasons for water leakage in the main driver's compartment of a car?

Reasons for water leakage in the driver and passenger compartments: 1. The windshield may not be properly sealed: gaps or improper welding of the metal plate under the wipers can cause leaks; 2. Poor quality of drainage pipes: some drainage pipes are of low quality, prone to aging and loosening, leading to bending of the pipe shape and poor drainage; 3. Disconnected condensate pipe: if there is water leakage in the passenger compartment while the air conditioning is on, it may be caused by a disconnected condensate pipe. Below is more information about the driver's compartment: 1. Introduction: The driver's compartment is an important part of the body of trucks and special vehicles, serving as the workplace for professional drivers day and night. 2. Classification: (1) Long-nose cab: located behind the engine, isolated from the engine, it does not overheat in summer and is less likely to let in exhaust fumes. (2) Flat-nose cab: with the engine located at the lower rear, it can reduce the vehicle's curb weight, improve maneuverability, and provide a wide field of vision.

What is an Automotive Starter Motor?

An electrically-driven device mounted on the engine, used to start diesel or gasoline engines. The starter motor typically consists of a transmission mechanism, control mechanism (solenoid switch), and a DC motor. The working principle of the starter motor is to convert the electrical energy from the battery into mechanical energy, thereby driving the flywheel on the engine to rotate, thus achieving engine startup. Symptoms of a faulty automotive starter motor are as follows: 1. Failure to start: When starting the car, the starter motor is unable to effectively drive the flywheel, sometimes turning and sometimes not. When the starter does not turn, there is a clicking sound from the solenoid switch, indicating possible damage to the starter motor or insufficient battery charge. 2. Starter motor catching fire: During vehicle startup, if the starter motor jams and emits smoke, severe overheating may cause a short circuit and fire. In such cases, immediately turn off the ignition key and disconnect the power to prevent a fire. 3. Frequent solenoid switch operation: During car startup, a disconnected starter wire may cause the solenoid switch to repeatedly engage and disengage, leading to frequent actions.
