Tire 12r22.5 refers to a tubeless radial tire with a section width of 12 inches and a rim diameter of 22.5 inches. The following are the functions of tires: 1. Support the entire weight of the vehicle: bear the load of the car and transmit power and torque in other directions; 2. Transmit traction and braking torque: ensure good adhesion between the wheel and the road surface to improve the car's dynamic performance, braking performance and passability; work with the car suspension to mitigate the impact during driving and attenuate the resulting vibration; 3. Prevent severe vibration and early damage of auto parts: adapt to the high-speed performance of the vehicle and reduce driving noise, ensuring driving safety, handling stability, comfort and energy-saving economy.

How Much Can Be Refunded for Driving School?

Vehicle driver's exam refund process and standards are as follows: 1. Failed medical examination: If the applicant fails the medical examination after registration, no fees will be charged. 2. Did not take the exam: For applicants who passed the medical examination but did not take the subject one exam, a full refund will be issued if no training was attended (excluding book fees). 3. Passed the medical examination and took the subject one exam: The applicant must go directly to the driving school's registration office to complete the withdrawal procedures, and the remaining balance will be refunded after deducting the fees for the training hours already taken. 4. Applicants who have participated in subject two or subject three training and request to withdraw: After deducting the training hours for each subject as stipulated by the price department, the remaining balance will be refunded.

Does the 2021 Bora 6AT Transmission Have Jerking Issues?

2021 Bora 6AT transmission jerking may be caused by internal friction plate failure, abnormal transmission oil pressure, or transmission valve body malfunction. Here are the specific details: 1. Solution: Generally, avoid disassembling first and then searching for replacement parts after identifying the damaged components. This approach often leads to difficulties in sourcing parts and the awkward situation of being unable to reassemble due to damaged seals, gaskets, etc. It is recommended to conduct a safety inspection at a 4S shop to ensure driving safety. 2. Transmission: The transmission is a very important component in a vehicle. It can change the transmission ratio and expand the torque and speed of the drive wheels. The performance of the transmission is key to measuring the power, economy, and drivability of engineering machinery.

Is 4 liters of engine oil enough for the Roewe RX5?

Adding 4 liters of engine oil is sufficient. The user manual for the Roewe RX5 specifies that the engine oil filling capacity is between 4 to 5 liters, so as long as it falls within this range, it is acceptable. Precautions when adding engine oil: Select engine oil based on the engine's requirements: Do not use high-grade oil in a lower-performance engine, nor use low-grade oil in a high-performance engine. Choose oil that matches the engine. The oil level should be slightly below the mark on the dipstick; do not overfill: Excessive oil not only increases the crankshaft's rotational resistance but also reduces the engine's output power. Moreover, the excess oil may enter the combustion chamber and participate in combustion, leading to oil burning, blue smoke emission, and increased fuel consumption.

What is the standard tire pressure for cars in summer?

In summer, the tire pressure for cars can generally be set to the lower limit of the standard tire pressure. For example, the lower limit for standard tires is 2.4 bar. If the car is often parked outdoors, the tire pressure can be about 0.1 bar lower than the standard to prevent tire blowouts due to high temperatures. Hazards of excessive tire pressure: The friction and adhesion of the tires will decrease, affecting braking performance; It can cause steering wheel vibration and deviation, reducing driving comfort; Accelerates localized wear of the tread pattern in the center of the tire, 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 car while 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.

What Causes Car Idle Shaking?

Car idle shaking can be attributed to the following reasons: 1. Unstable oil pressure: Abnormal fuel pump supply pressure or malfunctioning intake pressure sensor values can cause body shaking; 2. Severe engine carbon buildup: Dirty throttle body or excessive carbon deposits in fuel injectors; 3. Ignition system issues: Poor ignition system performance or suboptimal spark plug firing conditions can also lead to such faults; 4. Aging engine components: Engine mounts are responsible for absorbing minor vibrations during operation. If the engine mounts fail, these vibrations will transmit to the steering wheel and cabin, causing shaking during idle.

How to Handle License Plate Transfer?

The conditions for swapping license plates under the same owner are as follows: 1. If either of the two vehicles involved in the swap has any traffic accidents or violations, these issues must be resolved first, including handling the accidents or paying the fines; 2. The owner of the different license plates to be swapped must be the same person; 3. If a license plate swap between different vehicles has already been applied for within the year, another swap can only be done after a full year has passed; 4. Only non-commercial vehicles can swap license plates, and both vehicles must be of the same class and have the same type of license plate. Relevant information about license plates is as follows: 1. Introduction: License plates, commonly known as vehicle plates, refer to the plates attached to the front and rear of a vehicle, displaying the vehicle's registration number, registration region, or other relevant information. 2. Function: License plates serve as a numbering and information registration system for vehicles. Their primary purpose is to identify the vehicle's region of registration and to allow for the tracking of the vehicle's owner and registration details based on the plate number.
