There are many reasons for low tire pressure, mainly including tire damage and slow air leakage caused by tire aging. Hazards of excessive tire pressure: The friction and adhesion of the tire will decrease, affecting braking performance; it causes steering wheel vibration and deviation, reducing driving comfort; accelerates uneven wear of the central tread pattern, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overextends the tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; decreases puncture resistance. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, causing internal cracks or blowouts due to impact, leading to tire bursts. Hazards of insufficient tire pressure: Increases friction with the road surface, leading to higher fuel consumption; makes the steering wheel heavy and prone to deviation, creating unsafe driving conditions; increases movement in various parts of the tire, causing abnormal heat due to excessive rolling; reduces the functionality of the cords and rubber, leading to delamination or cord breakage, and excessive friction with the rim causing damage to the bead area and abnormal wear; multiplies friction with the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in tire bursts; increases tire body deformation, making the sidewalls prone to cracks and generating flexing movements, leading to excessive heat, rubber aging, cord fatigue, and breakage, while also increasing the tire's contact area with the ground, accelerating shoulder wear.

How to mortgage a car that is not under my name?

Normally, only the owner of the car can mortgage it at the vehicle management office. If you want to mortgage a car that is not under your name, you need the consent of the vehicle owner. This type of loan is called an auto title loan, where the borrower or a third party uses the car as collateral to obtain a loan from a financial institution or auto finance company. To apply for a mortgage registration, you need to fill out the "Motor Vehicle Mortgage/Cancellation of Mortgage Registration Application Form" and provide the following documents, which must be submitted jointly by the vehicle owner (mortgagor) and the mortgagee: 1. Identification documents of the mortgagor and mortgagee; 2. The motor vehicle registration certificate; 3. The principal contract and mortgage contract legally established between the mortgagor and mortgagee. The vehicle management office will record the mortgage registration details on the motor vehicle registration certificate after processing the application.

What are the precautions for automatic transmission vehicles passing through deep water?

Precautions for automatic transmission vehicles passing through deep water are: 1. Do not stop, accelerate, shift gears, or release the throttle when driving through deep water; 2. If the vehicle stalls in water, take measures to quickly move the vehicle out of the flooded area. The submerged vehicle should be towed away from the water as soon as possible to prevent the wheels from causing the engine to rotate in reverse during towing, which could damage components such as cylinders, connecting rods, and pistons; 3. When towing, use a rigid towing method to avoid engine damage caused by accidental gear engagement; 4. After the submerged vehicle is towed out of the water, promptly conduct a thorough inspection of all water-soaked electrical components.

What is the 0-100 km/h acceleration time of the Magotan 330?

According to official data, the Magotan 330 is available in two engine displacements: 1.4T and 2.0T. The 1.4T variant achieves a 0-100 km/h acceleration time of 10.41 seconds, while the 2.0T variant accomplishes it in 7.82 seconds. Factors affecting a vehicle's 0-100 km/h acceleration time include: Torque: In simple terms, torque represents the strength of the engine. The greater the torque, the stronger the force pushing the vehicle, resulting in faster acceleration. The Magotan 330 2.0T has a 0-100 km/h acceleration time of 7.82 seconds with a maximum torque of 250 Nm, while the Passat 2.0T achieves it in 7.4 seconds with a maximum torque of 350 Nm. Transmission efficiency: The transmission acts as a medium for power delivery and inevitably involves power loss. Higher transmission efficiency leads to better acceleration performance. Generally, the ranking of transmission efficiency is as follows: manual transmission > dry dual-clutch transmission > wet dual-clutch transmission > AT transmission > CVT transmission. The Magotan 330 is equipped with a seven-speed wet dual-clutch transmission. Power-to-weight ratio: The relationship between horsepower and vehicle weight is referred to as the power-to-weight ratio (unit: Hp/T). A higher power-to-weight ratio results in faster acceleration. The Magotan 330 2.0T has a 0-100 km/h acceleration time of 7.82 seconds with a power-to-weight ratio of 100 Hp/T, while the Passat 2.0T accomplishes it in 7.4 seconds with a power-to-weight ratio of 138 Hp/T.
