Is It Normal for New Car Wheels to Have Lead Weights?

It is normal for new car wheels to have lead weights. These are added by the manufacturer during production when the tire's dynamic balance is found to be unstable. For the tire and rim assembly, the mass cannot be perfectly evenly distributed, so when it rotates, it tends to create vibrations relative to the rotational axis. The added lead weights are made of lead alloy, measured in grams, such as 5g, 10g, 15g, etc. Each weight has a steel hook that can be clipped onto the edge of the wheel rim. Tire dynamic balance testing method: Tires should undergo regular dynamic balance checks using a dynamic balance tester. Tire balance is divided into dynamic balance and static balance. Dynamic imbalance can cause the wheel to wobble, leading to wave-like wear on the tire, while static imbalance can cause bumps and jumps, often resulting in flat spots on the tire. Purpose of tire dynamic balancing: Dynamic balance refers to the tire and wheel assembly as a whole, while wheel alignment pertains to the entire suspension system. These are different components. Therefore, regular balance checks not only extend tire life but also improve driving stability, preventing accidents caused by tire wobbling or jumping at high speeds, which could lead to loss of control.

Can I leave directly after signing for passing the Subject 1 test?

You can leave after signing your name upon completing the Subject 1 test. The signature indicates that the examinee has confirmed their score, and the vehicle management office can use this to upload the information. Subject 1 test procedure: Arrive at the test center at the scheduled time with your ID card and student permit; after hearing the voice prompt, verify your identity before entering the test room; follow the staff's instructions to find your assigned seat; log in and click "Confirm"; enter your personal information as prompted; after successful entry, verify your basic details and click "Start Exam" if everything is correct; begin answering questions in the exam system; click "Submit" after completing the test and confirm submission; review your score after submission, confirm it on-site, and then sign to leave the test room. If you fail the first attempt, you can prepare for a second retake under the staff's guidance. Subject 1 test precautions: There will be a camera on the desk or computer during the test. Ensure the camera is aimed at your face and clearly captures your facial features by observing the monitor display. Avoid positioning the camera on other body parts or showing only half your face. Once the allotted 45 minutes elapse, the computer will automatically submit your test. Examinees who finish early can also submit ahead of time, and the system will display the test score within about five seconds. Regardless of whether you pass or fail, you must confirm your score with the proctor and sign before leaving.

What is the service life of a car seat belt?

Seat belts generally have a service life of 3 to 5 years. The specific duration depends on the level of care during regular use. Seat belts should be inspected periodically to extend their lifespan. However, if a seat belt cannot be tightened properly, it should be replaced immediately to prevent safety hazards. During a collision while driving, passengers may lurch forward, subjecting the seat belt to significant impact, which necessitates prompt replacement. Seat belts are devices installed in vehicles to reduce passenger and driver injuries when the car body experiences severe impact. Public security authorities mandate that all front-seat occupants must wear seat belts, as they provide restraint and cushioning during traffic accidents, preventing secondary injuries. In addition to seat belts for both front and rear seats, cars are also equipped with airbag systems. In the event of a collision, the airbags automatically inflate and deploy to prevent occupants from hitting the car body, thereby protecting them.

Which Cars Use 95 Octane Gasoline?

95 octane gasoline is suitable for high-end vehicles and imported models with a compression ratio between 8.5-10.0. In daily driving, car owners should refer to their vehicle's manual or the label on the fuel tank cap to determine the appropriate gasoline grade. To avoid engine damage, never use gasoline with an incorrect octane rating. Distinguishing by octane rating: To differentiate between 92 and 95 octane gasoline, you need to understand octane ratings. The octane rating measures how resistant gasoline is to knocking, which is essentially an abnormal combustion phenomenon in the engine. Do not mix different octane ratings: 92 octane gasoline has an octane rating of 92, while 95 octane gasoline has a rating of 95—both have fixed values. Moreover, gasoline with different octane ratings should not be mixed. It's crucial to know which type of gasoline your car requires. First, remember what type of gasoline your car needs; then, keep in mind that two different octane ratings should never be mixed.
