The new regulations for wheel hub modifications are as follows: 1. Legal: According to the relevant provisions of the current "Motor Vehicle Registration Regulations," any changes to the body color, model, performance, purpose, or structure of a licensed motor vehicle, including replacing the frame, body, or engine, must be reported to the vehicle management office for modification registration. Installing spoilers, extensive body kits, or modifying exhaust pipes is generally not allowed. Before modifying a vehicle, detailed modification plans must be submitted to the traffic authorities for review. Only after approval can the modifications be legally carried out, and they must also be approved by the transportation department. 2. Safety: Forcing the installation of 17-inch wheels means the interaction force between the tire and the wheel hub will be significantly lower than the required value, whether in the longitudinal or lateral direction. Longitudinally, during braking or acceleration, the tire and wheel hub may experience relative rotation. Laterally, during turns, the tire is highly prone to detaching from the wheel hub, which is extremely dangerous.

Do I Need to Replace the Locks If I Lose My Car Key?

If you lose your car key, you can go to a 4S store to replace the locks or get a new key. The data of the lost key will be deleted, and after deletion, the vehicle cannot be started. More detailed solutions for losing a car key are as follows: 1. If it is a mechanical key, purely mechanical car keys are rare nowadays and are mostly found in some low-end models. This type of key is as simple as different door lock keys, with one key capable of opening the car door, trunk, and starting the engine. Therefore, whether you have a spare key or not, it is best to replace all the car locks to avoid significant security risks. 2. If it is an electronic anti-theft key, an electronic anti-theft key adds a remote control to the mechanical key, with the remote control's function being to open the car door or windows. If this type of key is lost, you can use the spare key to replicate and match a new one. Although the remote control of the lost key cannot open the car door, it can still forcibly open the car door, trunk, or start the engine, so it is still advisable to replace all the car locks. In daily use, car owners should take good care of their car keys. Dropping the key or getting it wet is common, but severe impacts can easily damage the internal chip of the key. Also, avoid getting the key in contact with liquids and keep it away from strong magnetic fields. Always keep the commonly used key and the spare key separate.

How to Install Eccentric Bolts on a Car?

1. When installing eccentric bolts on a car, if the camber angle is large, the belly of the bolt should face inward; if the camber angle is small, the belly of the bolt should face inward. Adjust while measuring. 2. Toe-out indicates a negative camber angle, while toe-in indicates a positive camber angle. If the eccentric bolt is on the lower control arm and the camber angle is negative, the belly should face outward; if positive, it should face inward. 3. Additional Information: The purpose of eccentric bolts is to adjust angles during wheel alignment. For example, if the wheel camber angle exceeds the standard range, it can only be adjusted using eccentric bolts. Using eccentric bolts ensures proper wheel alignment, prevents tire wear, and maintains safety.

After how many years does a vehicle require biannual inspections?

For small and micro non-commercial passenger vehicles over 15 years old, inspections are required every 6 months; for commercial passenger vehicles over 5 years old, inspections are required every 6 months; for trucks and large/medium non-commercial passenger vehicles over 10 years old, inspections are required every 6 months. Vehicle inspection content: Check whether the engine, chassis, body and auxiliary equipment are clean, complete and effective, whether the paint surface is uniform and aesthetically pleasing, whether major assemblies have been replaced, and whether they match the initial inspection records; Verify whether the vehicle's braking performance, steering control, lights, exhaust and other safety performance meet the requirements of the "Technical Conditions for Safe Operation of Motor Vehicles"; Check whether the vehicle has been modified, reconstructed or transformed, whether the driving license, license plate and vehicle registration records match the actual vehicle condition, and whether approval and modification procedures have been completed; Check whether the license plate, driving license and enlarged license plate markings on the vehicle are damaged, altered or illegible, and whether replacement is needed; For large vehicles, check whether the unit name or the street/township/town name and the maximum seating capacity in the cab are printed in Chinese imitation Song font on both sides of the door as required; For trucks, check whether the rear tailgate (including the trailer's rear tailgate) exterior displays the license number enlarged 2-3 times as required, and whether the sides of the door display the word "individual" for private or jointly operated vehicles. The markings must be clear, and unit codes or other patterns are not allowed (special circumstances require approval from the vehicle management office).

How Far Can a Car Go After the Fuel Gauge Reaches the Red Line?

Generally, when a car's fuel gauge needle reaches the red line, there is approximately 10% of fuel left in the tank, allowing the car to travel an average of 20-60 kilometers further, depending on the vehicle model. Regarding refueling, here are three recommendations: 1. Do not wait until the warning light comes on to refuel. Since the fuel pump is located inside the tank and relies on gasoline for cooling and lubrication, insufficient fuel can hinder the pump's normal operation and shorten its lifespan. 2. It is not advisable to fill the tank completely. Gasoline expands when heated and evaporates into vapor under high summer temperatures, requiring space to accommodate this. If the tank is filled to the brim with no space left, gasoline vapor or even liquid gasoline may enter the carbon canister for storage. Once the carbon canister is full, the excess vapor escapes into the air, leading to waste and environmental pollution. 3. Indicator deviation. After routine activities such as replacing the battery or fuel filter, or even after parking overnight, you might notice the fuel gauge needle showing a lower level than before upon restarting the vehicle, mistakenly thinking it's a malfunction. However, this is actually a normal phenomenon.

How long after running a red light will you be notified?

After running a red light, the illegal photo SMS notification is usually received within 3 to 7 days, with a maximum delay of around 13 days. However, some cities have now introduced "instant electronic police capture alerts," where you can receive an SMS notification within 5-10 minutes of being captured. But this notification does not equate to a traffic violation; it serves merely as a capture alert. The final determination of whether a violation has occurred still takes 3-7 days. If it is indeed a violation, you will receive another SMS notification. For traffic violations captured by surveillance cameras, vehicle owners generally do not receive the violation SMS immediately. There is a delay, and the duration may vary. This is because after the electronic camera captures the violation, the relevant violation information needs to be transmitted through a dedicated channel to the traffic police management center. It is then compiled and forwarded to the relevant traffic police personnel for verification. Once confirmed as a violation, the system automatically retrieves the vehicle owner's phone number based on the license plate information and sends the violation details via SMS. After receiving the violation SMS, the vehicle owner must go to the traffic police department where the violation occurred to settle the matter within one month before the vehicle's annual inspection. Generally, if a vehicle owner suspects they have committed a violation, they can use 15 days as a benchmark. If no violation SMS is received beyond 15 days, it is likely that no violation was recorded. Traffic Violation Query Methods: Traffic violation queries refer to checking motor vehicle violations of traffic regulations through online platforms or query terminals. There are five main methods for vehicle violation queries: traffic branch terminal queries, vehicle violation website queries, phone queries, SMS queries, and mobile app queries. Website Query: You can search for "vehicle violation query" and input your vehicle information to check. Phone Query: To query violations, you can call the local 114 (area code + 114) or 12580 for confirmation. Violations can only be processed at the location where the violation occurred or where the vehicle's license plate was issued. For on-the-spot violations, such as those caught directly by a traffic officer, they must be handled at the violation location. SMS Query: Open your phone's SMS interface, type "WZ [license plate number] [license plate color]" in the message body, and send it to 1062650001. Mobile App Query: Open the Traffic Management 12123 app, select "Violation Query," and clear any unresolved violations.
