Will a tire pressure of 3.0 cause a blowout on the highway?

A tire pressure of 3.0 will not cause a blowout on the highway. The reason it won't blow out is that the manufacturer's recommended tire pressure includes a 30% safety margin. Tires can withstand pressures as high as 3.5 to 4.2 bar, meaning their capacity exceeds actual requirements. The normal tire pressure range for cars is between 2.3 and 2.5 bar. For safety reasons, it is recommended to reduce the tire pressure to within the normal range before driving on the highway. A tire pressure of 3.0 on the highway can negatively impact tire lifespan and driving safety, potentially accelerating central tread wear, causing abnormal tire wear, shortening tire lifespan, and making the tires too hard, which could indirectly damage other vehicle components.

Is an Automatic Transmission Easier to Test Than a Manual Transmission?

Automatic transmission is easier to test than manual transmission in the Subject 2 driving test. Compared to manual transmission, the main difference with automatic transmission is that it does not require clutch control, making it simpler. Additionally, during steep hill starts, manual transmission vehicles may stall, exceed time limits, or roll backward, whereas automatic transmission vehicles do not stall. The similarity is that both require the driver to assess the vehicle's driving conditions. Below are the differences between manual and automatic transmissions: 1. Different Learning Costs: Generally, the tuition fee for learning automatic transmission is higher than for manual transmission, typically around 500 RMB more than the manual transmission price. This is because the purchase cost, usage cost, and maintenance cost of automatic transmission vehicles are higher than those of manual transmission vehicles. 2. Different Eligible Vehicle Types: A manual transmission (C1) license allows the holder to drive small and micro passenger cars, light and micro trucks, light and micro special-purpose vehicles, and all vehicle types permitted under the C-class driver's license. In contrast, an automatic transmission (C2) license only permits driving small and micro automatic transmission passenger cars and light and micro automatic transmission trucks. 3. Different Test Items: Starting from June 1, 2021, the "hill start and stop" item will be removed from the Subject 2 test for small automatic transmission vehicles. This means that the test items for automatic transmission vehicles in Subject 2 will be fewer than those for manual transmission vehicles.

Is it normal to feel a jolt when shifting from N to D gear?

For automatic transmission vehicles, experiencing a jolt or jerk when shifting between D and N gears is mostly normal, and it is unlikely to be a malfunction if the car is new. When in D gear, the engine disconnects from the transmission. AT/CVT transmissions, which use a torque converter structure (a soft connection), tend to have slightly less noticeable jolts, while DCT/AMT transmissions, which use a clutch for rigid connection and disengagement, may produce more pronounced jolts. Below is some relevant information: 1. Rear-wheel-drive vehicles tend to exhibit more noticeable jerks when shifting to neutral, and you may observe the rear of the vehicle sinking slightly. This occurs because, after shifting from drive to neutral, the transmission's driveshaft and differential undergo a process of releasing force. The sudden interruption of power and the gap created by gear disengagement contribute to this sinking sensation. 2. Even new cars can exhibit these behaviors, and they are not considered malfunctions. Feeling a jolt when shifting from N to D gear while holding the brake is entirely normal—it results from the opposition between braking force and engine power. Some cars may produce a "clunk" sound when releasing the brake, which is simply the vibration from the brake pads separating. This is also normal. 3. Automatic transmissions are designed for convenience, but their fundamental principles of power transfer are no different from manual transmissions. As long as the engine's power needs to be transmitted to the wheels through the transmission, there will inevitably be some opposition of forces. Occasional noises or minor jerks should not be a cause for concern.

What displacement is equivalent to a 1.2T engine?

1.2T is equivalent to the horsepower output of a 1.6 to 1.8-liter naturally aspirated engine. A 1.2T engine is essentially a 1.2-liter naturally aspirated engine equipped with a turbocharger to enhance its power and torque output. The 'T' primarily increases the power, while the displacement remains unchanged at 1.2 liters. Similarly, a 1.0T engine still has only 1.0-liter displacement and does not increase the actual engine displacement due to turbocharging. Under the same displacement conditions, a 1.0T engine delivers more powerful performance than a 1.0-liter naturally aspirated engine and can also achieve better fuel efficiency to some extent.

What is the penalty for driving a B-license vehicle with a C license?

C license holders driving B-license vehicles will have 12 points deducted. Driving a B-license vehicle without obtaining a B license upgrade is considered unlicensed driving, punishable by a fine ranging from 200 to 2,000 yuan. According to the "Point Deduction Standards for Road Traffic Violations": Article 1, motor vehicle drivers committing any of the following violations will have 12 points deducted at once. Point 1: Driving a motor vehicle that does not match the permitted vehicle type on the driver's license. The following are the relevant provisions of the "Road Traffic Safety Law of the People's Republic of China": 1. Article 19: To drive a motor vehicle, one must obtain a motor vehicle driver's license in accordance with the law. To apply for a motor vehicle driver's license, one must meet the driving license conditions stipulated by the public security department under the State Council; after passing the examination, the traffic management department of the public security organ will issue a motor vehicle driver's license of the corresponding category. 2. Holders of foreign motor vehicle driver's licenses who meet the driving license conditions stipulated by the public security department under the State Council and pass the assessment by the traffic management department of the public security organ may be issued a Chinese motor vehicle driver's license. Drivers must drive motor vehicles according to the permitted vehicle type specified on their driver's license; when driving a motor vehicle, they must carry the motor vehicle driver's license with them. No unit or individual other than the traffic management department of the public security organ may confiscate or detain a motor vehicle driver's license. 3. Article 22: Motor vehicle drivers shall abide by the provisions of road traffic safety laws and regulations, and drive safely and civilly in accordance with operational norms.

What are the precautions for long-term vehicle parking?

Precautions for long-term vehicle parking: 1. Clean the vehicle thoroughly to prevent flammable or explosive items inside from self-igniting after prolonged sun exposure; 2. Ensure the fuel tank is tightly sealed without any oil leaks or seepage, and avoid keeping the vehicle under constant direct sunlight, as this can raise the fuel tank temperature and increase risks; 3. Drive the vehicle for a certain distance weekly to keep it running, which helps maintain the components, prevents rust or corrosion, and clears carbon deposits; 4. Start the engine once a month to extend its service life; 5. Regularly check the battery to prevent excessive discharge.
