The cause is excessive air pressure during tire usage, which reduces the contact area with the ground, leading to premature tire wear. Due to accelerated tire rolling or poor heat dissipation, the tread temperature rises, resulting in bulges. Below is relevant information about tires: 1. Function: Supports the entire weight of the vehicle, bears the load of the car, and transmits forces and moments in other directions; transmits traction and braking torque to ensure good adhesion between the wheels and the road surface, improving the car's power, braking, and passability; works with the car suspension to mitigate impacts during driving. 2. Lifespan: The lifespan of a tire is related to many factors, such as climate, road conditions, driving style, installation, maintenance, etc. According to international regulations, if the tire is used normally, it must be replaced when the tread depth wears down to 1.6 millimeters.

Can points be deducted during the probationary period of a driver's license?

Points can be deducted during the probationary period of a driver's license. If a motor vehicle driver accumulates 12 points during the probationary period of their driver's license, their driving qualification for the probationary vehicle type will be revoked. For a C1 driver's license, as long as the points do not reach 12 and the fines are paid, the points will be cleared at the end of the probationary period. If the fines are not paid, the points will automatically carry over to the next scoring cycle. The probationary period for a C1 license will not be extended; the extension of the probationary period only applies to Class A and B driver's licenses. The probationary period for a motor vehicle driver is the first 12 months after initially applying for a motor vehicle driver's license or adding a new vehicle type to their license. For those who newly obtain a driver's license for large buses, tractors, city buses, medium-sized buses, or large trucks, within 30 days after the end of the probationary period, they must take a test on road traffic safety laws and regulations, safe and civilized driving, emergency handling, and other knowledge, and receive no less than half an hour of education on traffic accident case warnings.

Engine oil plays roles in lubrication, cleaning, sealing, buffering, rust prevention, and heat dissipation within the engine. When the engine oil level is low, it must be replenished promptly, as the performance of the oil affects the engine's working condition and its service life. The Bora is FAW-Volkswagen's first independently designed model, equipped with a 1.8L naturally aspirated engine and a 1.8T turbocharged engine.
