Is Wheel Balancing Unnecessary After Rear Tire Repair?

Wheel balancing is required after rear tire repair. Generally, modern tires are tubeless, so when a tire needs repair, it must be removed from the wheel rim. Once removed, repaired, and reinstalled, wheel balancing becomes necessary. Here are situations that require wheel balancing: 1. After installing a new tire (post-repair) or after collision damage repairs; 2. Unilateral wear on front or rear tires; 3. Heavy steering wheel or floating/shaking during driving; 4. Vehicle pulling to the left or right when driving straight; 5. For maintenance purposes, it is recommended that new cars undergo wheel balancing after 3 months of driving, and subsequently every six months or 10,000 kilometers.

How to Clean Loop Car Mats?

Cleaning loop car mats can be done as follows: 1. Plastic mats: Plastic mats are the easiest to clean. This type of mat can be rinsed directly with water. Use some detergents like laundry powder or dishwashing liquid, then scrub with a brush and rinse with water to make them look brand new. 2. Plush mats: If plush mats are not particularly dirty, you can use a vacuum cleaner directly on them to remove dust or scrub with a brush to clean. If they are too dirty, you can soak them in water first and use a professional carpet cleaner for washing. Do not use ordinary detergents as they may damage the mats. The soaking time should not exceed fifteen minutes. After soaking, knead and wash, then fold the mat and put it into a spin dryer to remove water. Finally, place it in a cool, ventilated area to dry naturally. Avoid direct sunlight and wringing dry.

What is the function of 'A' in the car?

The 'A' in the car refers to the Auto Hold function. After turning on this switch, when the vehicle brakes during driving, even if the brake is released, the vehicle will not continue to move. It will only resume driving when the driver presses the accelerator. The features of the Auto Hold function are: 1. It prevents the vehicle from rolling when stopping briefly at traffic lights; 2. When starting on an uphill, the system automatically brakes to prevent rolling back, and releases the wheels to move forward once starting; 3. For parking and locking, there's no need to pull the handbrake as the system automatically brakes the wheels, but this feature is only available in some car models. Steps to use Auto Hold: 1. Press the car's brake pedal; 2. Press the car's one-touch start button; 3. The car's dashboard lights up, and the vehicle's power is fully connected; 4. Press the Auto Hold button inside the car to activate the Auto Hold mode.

What to Do When Tire Pressure Is Too High?

Tire pressure that is too high can affect vehicle performance, tire lifespan, and even driving safety. When tire pressure is excessive, it is necessary to release some air. If you have a dial-type tire pressure gauge, you can unscrew the tire valve cap, locate the center of the valve stem, and press lightly. Then, while referring to the pressure gauge, press the air release valve to observe the reading until the tire pressure returns to normal. Relevant information about tire pressure is as follows: 1. Introduction: Tire pressure, strictly speaking, refers to the air pressure inside the tire. In vehicle maintenance, the engine is the heart of the car—its failure can lead to the end of the car's life—while tire pressure is like the car's blood pressure. The level of tire pressure plays a crucial role in the vehicle's performance and power. 2. Hazards of excessive tire pressure: It reduces tire friction and adhesion, affecting braking performance; it can cause steering wheel vibration and deviation, lowering driving comfort.

How to Check if a Gas Station Has 98 Octane Gasoline?

Gas stations have 98 octane gasoline, but not every gas station carries it. You can use the Sinopec app to check the types of gasoline sold at each affiliated gas station. If it is listed, it means the station offers that service. Below is an introduction to gasoline characteristics: Anti-knock Property: The property that measures whether a fuel is prone to knocking is called anti-knock property. The anti-knock property of gasoline is indicated by the octane number (RON). The higher the octane number of gasoline, the better its anti-knock property. Cleanliness: Gasoline often contains mechanical impurities and water. Mechanical impurities can cause severe consequences such as clogging of fuel lines and increased wear. Water mixed into gasoline can accelerate oxidation and react with low-molecular-weight organic acids in gasoline to form acidic aqueous solutions that corrode metals. At low temperatures, water can freeze and form ice particles that clog fuel lines. Therefore, the presence of mechanical impurities and water in automotive gasoline should be strictly controlled.

Does an 8-year-old car that passed inspection last year need to be inspected again this year under the new regulations?

According to the new vehicle inspection regulations officially implemented on November 20, 2020, vehicles within 10 years only require inspection every 2 years. However, vehicles that were inspected before the new regulations took effect must undergo another inspection before the 2021 inspection validity period expires. Below are detailed explanations about the new inspection regulations: 1. Exemption details under the new regulations: New vehicles within 6 years can be exempted from inspection twice. Vehicles must undergo on-site inspection in their 6th and 8th years. For private vehicles over 10 years old, the original inspection cycle still applies. 2. Penalties for non-inspection: Motor vehicles driven on the road without license plates, inspection qualification labels, insurance labels, or without carrying the vehicle license and driver's license will be detained by traffic management authorities. The owner will be notified to provide the corresponding documents, labels, or complete necessary procedures, and will be penalized according to regulations.
