What does 92H in tires mean?

Tire marking 92H represents two specifications: the number 92 indicates the load index, meaning the tire can bear a maximum load of 630kg; the letter H denotes the speed rating, indicating the tire can support a maximum speed of 210km/h. Every tire is labeled with various parameters during production, such as tire size, load capacity, and maximum speed. Different letters on tires correspond to different speed capabilities. As one of the crucial components of a vehicle, tires directly contact the road surface and work in conjunction with the suspension system to absorb shocks during driving. They ensure good ride comfort and smooth driving performance, maintain excellent traction between wheels and road surfaces, and enhance the vehicle's traction, braking, and off-road capabilities.

Is the subject one test for a B2 license with 12 points deducted C1 or B2?

B2 license with 12 points deducted needs to be downgraded to a C1 motor vehicle driver's license. Within 30 days of the deduction, you must go to the vehicle management office to participate in the study of road traffic safety laws and regulations and take the test for downgrading the license to C1 subject one test. Calculation period: A violation point cycle is 12 months, calculated from the date of first issuance. Full 12 points deducted from the license: AB class licenses: If 12 points are deducted, the license is directly downgraded. Accumulating 12 points within a point cycle will result in the license being detained; within 15 days, you must go to the license issuance location or the location of the violation to participate in a 7-day study session; if the test is passed, the points will be cleared, and the motor vehicle driver's license will be returned; if the test is failed, you must continue to participate in the study and test; refusal to participate in the study or test will result in the public security traffic management department announcing the suspension of the motor vehicle driver's license.

Can a cut on the side of a tire be repaired?

A cut on the sidewall of a tire cannot be repaired; it depends on the depth of the cut. If the cut is deep, it is recommended to replace the tire immediately. Check the extent of damage: During the use of a car, the tires will inevitably suffer some damage. If the tire is damaged by a sharp object, it is necessary to check the extent of the injury. Generally speaking, most cars use radial tires, which have a relatively simple internal structure. Although a scratch on the sidewall may not cause a blowout, the tire should not be used for a long time after being damaged. It is recommended that car owners replace the tire immediately. Tires are made of rubber: Car tires are made of rubber, and the rubber layer has a certain thickness. However, the sidewall rubber is relatively thin, and its thickness is insufficient to provide adequate support for the tire, nor does it offer good protection. If the sidewall of the tire is damaged, it may affect the radial layer, which is the metal mesh inside the tire. If the metal mesh is significantly damaged, the structural integrity of the entire tire cannot be guaranteed. During high-speed driving, the tire may blow out, posing a threat to the safety of the occupants.

What to do if there is a cut on the tire?

Tire with a cut should be handled as follows: 1. If the scratch is caused by a blunt object, the surface will appear uneven, and there may be debris like small stones inside the scratch. In this case, it is recommended to visit a professional tire dealer for inspection to determine if it can be repaired; 2. If the tire is damaged by a sharp object, it is likely caused by sharp debris while driving. Such damage usually has a small cut surface but can be very deep. If the radial structure inside the tire is damaged, replacement is recommended. For radial tires, if obvious side scratches are visible to the naked eye, immediately replace with the spare tire and drive to a repair shop for a tire change. For bias-ply tires, due to their sturdy rubber and metal layers, if the scratch is not deep, it can be ignored or repaired. However, if the scratch is deep, replacement is still recommended.

How to adjust the brakes on a diesel vehicle with hydraulic brakes?

Hydraulic brakes on vehicles cannot be adjusted as they are a transmission system of oil pump pressure. The only requirement is to ensure sufficient brake fluid. To add brake fluid, follow these steps: 1. Open the driver's side door and pull the hood release lever located on the left side near the driver's leg. 2. Lift the engine hood upwards and secure it with the support rod. 3. Top up the specified brake fluid to the MAX level. Additional information: 1. The hydraulic brake system is simple in structure and requires minimal installation space, consisting only of the master cylinder, wheel cylinders, fluid reservoir, and connecting pipelines, without the need for additional auxiliary equipment. 2. Hydraulic brakes have a slightly slower response time but provide a gentler and less forceful braking action, whereas air brakes respond more quickly but deliver a harsher and more forceful braking effect.

What does the lightning fault light mean?

The lightning fault light is the electronic throttle warning light. The electronic throttle is an important control component of the car engine, composed of the engine, speed sensor, throttle, etc. The use of an electronic throttle control system allows precise control of the throttle opening. Electronic throttle principle: The principle of the throttle is that the traditional engine throttle operating mechanism works through a cable (soft steel wire) or rod, with one end connected to the accelerator pedal and the other end connected to the throttle linkage plate. The electronic throttle mainly uses the throttle position sensor to control the throttle opening angle according to the energy required by the engine, thereby regulating the amount of air intake. Solutions for throttle faults: Troubleshoot the intake system, use fuel that meets standards, clean the throttle body; remove carbon deposits from related parts; rewrite the ECU-related data. When the throttle indicator light is found to be on, you can first try to turn off and restart the engine to see if the throttle light is still on. If it is not on, it means there is no problem, and it is just a false alarm caused by the EPC light being affected.
