Is Wheel Balancing and Four-Wheel Alignment Necessary When Changing Car Tires?

Wheel balancing is required when replacing tires. If wheel balancing is not performed, the tire's weight distribution will not align on a central axis during rotation, causing the wheels to wobble from side to side, which in turn leads to vibrations in the car body and steering wheel. Relevant parameters for changing rims: 1. Center Bore (CB): Refers to the size of the rim's center hole. Although rims with different center bore sizes from the original can be installed using adapters, it is not recommended for safety reasons. 2. Pitch Circle Diameter (PCD): This value should match the original specifications. For example, a rim with a PCD of 5x120mm means it has five lug bolts forming a circle with a diameter of 120mm. 3. Offset (OFFSET): Also known as the ET value. A positive offset means the mounting surface is outside the centerline, while a negative offset means it is inside. Passenger cars generally have a positive offset, and this value significantly affects driving stability and cornering traction.

When it comes to changing car tires, I believe wheel balancing is absolutely necessary. If new tires aren't balanced after installation, you'll experience steering wheel vibration and unstable vehicle handling at high speeds, which not only affects driving comfort but can also lead to premature tire wear. Wheel alignment, however, isn't required every time unless you notice the car pulling to one side, uneven tire wear patterns, or if there's been previous collision damage. Tire replacement itself doesn't alter suspension geometry, so balancing alone suffices for routine maintenance. With over a decade of driving experience, I always insist on balancing with every tire change - it's a simple, essential procedure that uses small lead weights clipped to the wheel rim to adjust weight distribution, ensuring peace of mind and preventing future complications.

What causes the buzzing noise when the car reaches 100 mph?

The reasons for the buzzing noise when the car reaches 100 mph are: 1. Engine noise, some parts are excessively worn or improperly assembled and adjusted; 2. Transmission noise, often due to faulty gear shafts or insufficient transmission oil; 3. Wear-related noise, some noises from certain parts of the car body when stepping on the accelerator or brake. Engine noise indicates that the technical state of a certain engine mechanism has changed. Some noises can also predict potential catastrophic damage to the engine, but there are exceptions, such as the sharp screeching sound of a belt, which is usually caused by belt slippage. A sharp metallic friction sound is generally due to damage to the bearings of the generator, water pump, or power steering pump. When engine noise occurs, it should be repaired promptly to prevent further damage.

How many points are deducted and what is the fine for driving against traffic on ordinary roads?

Driving against traffic on ordinary roads will result in a deduction of 3 points and a certain fine. The penalties for driving against traffic are as follows: 1. Driving against traffic on a one-way road: 3 points will be deducted for driving against traffic. 2. Crossing solid lines, double solid lines, or overstepping lines: Crossing solid lines, double solid lines, or overstepping lines will be considered as driving against traffic, while crossing dashed lines is allowed. If an accident occurs, it will be considered as driving against traffic, resulting in a deduction of 3 points and a certain fine. 3. Driving against traffic on a highway: This is completely dangerous. According to Article 25, if a motor vehicle driver violates this regulation, 12 points will be deducted, and a certain fine will be imposed. If the driver is still in the probationary period, the driver's license will be revoked, and the driver will need to retake the test.

How to Solve the Squeaking Sound from Car Doors?

Regularly adding lubricant can help maintain and prevent squeaking sounds from car doors. Here is some relevant information about car doors: Composition: A car door generally consists of three parts: the door body, door accessories, and the interior trim panel. Types: Forward-opening doors: These doors can still be closed with the help of airflow pressure even while the car is moving, making them safer. They also allow the driver to observe the rear more easily when reversing, which is why they are widely used. Reverse-opening doors: If these doors are not closed properly while the car is moving, they may be forced open by oncoming airflow, so they are less commonly used. They are generally only adopted to improve ease of entry and exit or for ceremonial purposes. Sliding doors: Their advantage is that they can be fully opened even when the distance between the car's side and an obstacle is minimal.

What are the effects of water entering the brakes?

When water enters a car's brakes, it can affect the resistance of the braking system. This reduces the friction on the tires, making it difficult to stop the vehicle promptly in case of emergencies or sudden situations. Additionally, water in the brakes can cause them to malfunction, posing potential safety hazards both for the driver and others on the road. More relevant information is as follows: Water can cause brake failure: It is crucial to prevent water from entering the brakes while driving, as this can lead to serious issues that are hard to manage. Moreover, this is not a good situation to be in. If your car's brakes do get water inside, it is essential to visit a local auto repair shop to have them adjusted. The moisture must be removed; otherwise, you may face a series of potential dangers while driving, which can also be a significant threat to your health.
