The difference between tire 91h and 91v lies in their speed ratings: the maximum speed for 91h is 210 kilometers per hour, while for 91v it is 240 kilometers per hour. The number 91 is the load index, indicating the maximum load the tire can carry at different air pressures. A 91v tire can bear a weight of 615kg at 2.5bar. Tires are one of the most important components of a car, directly in contact with the road and working together with the car's suspension to absorb shocks during driving. Their functions include: 1. Ensuring good ride comfort and smooth driving; 2. Ensuring excellent adhesion between the wheels and the road; 3. Improving the car's traction, braking, and off-road capability; 4. Supporting the weight of the car.

Can Motorcycles Be Purchased with a Loan?

Motorcycles can be purchased with a loan. Currently, loans are available for motorcycle purchases, though conditions may vary by location. Buyers typically need to provide identification documents, household registration, marriage certificate or single status proof, as well as work and company contact numbers. Below are two methods for obtaining a motorcycle loan: 1. Credit Card Installment Payment: (1) The buyer brings proof of income and ID to the bank to apply for a credit card. After receiving the card, they can pay in full at the motorcycle dealership and take the motorcycle home. (2) After payment with the credit card, the buyer calls the bank's service hotline to apply for installment repayment. They simply deposit money into the card each month for repayment, which is unrelated to the dealership and does not require a down payment. 2. Installment Payment at the Dealership: (1) The buyer's employer should provide proof to the dealership. (2) The dealership then obtains the motorcycle loan through the bank. (3) The buyer only needs to pay the bank's interest upfront, followed by installment payments as per the bank's terms. (4) The buyer will pay a certain percentage of interest.

Is the first maintenance of a motorcycle free?

The first maintenance of a motorcycle is free. The first maintenance for a motorcycle is relatively simple, mainly involving changing the engine oil and checking the tightening bolts of the frame. Therefore, manufacturers are not stingy with these minimal cost expenses. When purchasing a motorcycle, a bucket of the manufacturer's specified special oil is usually provided as a gift. Below is an introduction to motorcycle maintenance: 1. Change the oil frequently: Generally, during the break-in period of 500 km, the oil should be changed, and after completing the 1500 km break-in period, it should be changed every 2000 km. This is better for the motorcycle. 2. Clean the filter frequently: Most domestic motorcycles use sponge filters. It is best to apply a layer of oil on the surface after cleaning to enhance the filtering effect. 3. Use listening, looking, and discerning to check the condition of the motorcycle: For example, if you suddenly hear an abnormal sound from the engine, it usually means a part is broken or stuck. In this case, do not start the motorcycle. Professional repair is needed immediately. If the sound persists for a long time, it must be due to wear or looseness of a certain part, which must be replaced.

Can I Take the Subject 2 Test Without an ID Card?

You cannot take the Subject 2 test without your ID card. However, if your ID card is lost or expired, you can use a temporary ID card. If you don't have an ID card and need to use a temporary one, you must inform the driving test instructor in advance and follow the arrangements made by the driving school. According to Article 19, Paragraph 1 of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," "first-time applicants for a motor vehicle driving license must fill out an application form and submit their identity proof." Therefore, you can take the Subject 2 test with a temporary ID card. Additionally, it's important to note that the validity period of a temporary resident ID card is three months. You can take the Subject 2 test within this validity period, but you will not be allowed to enter the test site if the card has expired. Therefore, make sure to take the test within the validity period of the document. If the temporary ID card expires due to special circumstances, you should promptly apply for a formal ID card or a new temporary ID card. Subject 2, also known as the small road test, is part of the motor vehicle driving license assessment. It refers to the field driving skills test. For small vehicles (C1 and C2), the test items include five mandatory components: reversing into a parking space, parallel parking, stopping and starting on a slope, right-angle turns, and curve driving (commonly known as the S-turn). Some regions also include a sixth item: highway card collection. According to Article 25 of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses" (Ministry of Public Security Order No. 123), starting from June 1, 2021, the slope stop and start test is no longer required for C2 and C5 license applicants in the Subject 2 test. For large vehicles (AB licenses), the Subject 2 test covers 16 items. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," the 16 items for AB license Subject 2 tests include: reversing into a parking space, passing continuous obstacles, curve driving, highway simulation test, width-limited gate, bumpy road, single-plank bridge, narrow road U-turn, slope stop and start, parallel parking, highway emergency handling, mountain road simulation, right-angle turns, rain and fog weather simulation, highway tire blowout, and tunnel simulation driving.
