Can You Drive with a Flat Run-Flat Tire?

Run-flat tires can still be driven when completely flat, but only for a short distance. Run-flat tires are not actually explosion-proof. These tires rely on their stiff sidewalls to support the vehicle and allow continued driving for a limited distance when tire pressure is extremely low, enabling drivers to reach the nearest repair shop for tire inflation. The sidewalls of run-flat tires are extremely rigid and can fully support the vehicle's weight even when the tire is deflated. However, due to their high rigidity, the sidewalls are prone to bulging. When using run-flat tires, it's important to note that you should reduce speed when driving over potholes or speed bumps, as the stiff sidewalls are susceptible to bulging under impact. Regular tire inspections are essential during routine vehicle use. Before long-distance or high-speed driving, always check tire pressure and inspect the tire surface for damage. As rubber products, tires degrade over time. It's recommended to replace tires every four years, even if the mileage is low during that period.

What Causes the Low-Pressure Pipe of a Car's Air Conditioning to Overheat?

There are several reasons why the low-pressure pipe of a car's air conditioning may overheat: 1. The evaporator is clogged, refrigerant flow is insufficient, or the pipeline pressure is too high. 2. Excessive dirt buildup on the condenser's copper pipes/fins reduces heat exchange efficiency. 3. Malfunctions in the compressor or expansion valve can also cause this issue. Here are some solutions for an overheating low-pressure pipe in a car's air conditioning: 1. Check if the air conditioning evaporator is clogged and clean any debris. 2. If the low-pressure pipe overheats due to a refrigerant leak, locate and repair the leak before refilling the refrigerant to restore normal operation. 3. Poor heat dissipation from the air conditioning condenser can also lead to inadequate cooling performance, so cleaning the condenser is necessary.

What is the Used Car Brokerage Business?

There are three types of used car business models: auction companies, brokerage companies, and dealership companies, each with certain operational restrictions. Auction companies: They cannot be a party to the transaction and are only allowed to act as intermediaries and collect commissions. Brokerage companies: They engage in consignment sales, information services, and provide sales venues, among other services. Dealership companies: They purchase vehicles from sellers and resell them, and are not allowed to engage in intermediary services. Below are the considerations for personal used car transfers: 1. Ensure the title certificate is legitimate: Pay special attention to the embossed number, engine number, and registration date on the title certificate. Besides verifying these details, check for any signs of alteration, as alterations may indicate a fraudulent transaction. 2. Check for any traffic violations: Before transferring a personal used car, check if the vehicle has any outstanding traffic violations and whether it is within the validity period of the compulsory traffic insurance. The vehicle must have no outstanding violations and valid insurance to proceed with the transfer. Generally, vehicles with violations cannot be transferred until the violations are resolved. 3. Verify the presence of vehicle purchase tax payment receipts: Always inspect the original tax receipt when transferring a personal used car. Some vehicles may not have paid the purchase tax, and after the transfer, these vehicles may be required to pay the outstanding tax, which can be a significant expense. Therefore, it is crucial to determine who will cover this cost.

What items are included in the second maintenance?

The second maintenance for a car includes changing the engine oil, air conditioning filter, oil filter, air filter, as well as inspecting the engine and tire conditions. Additionally, a comprehensive cleaning of the vehicle will be performed. Below is a detailed explanation: 1. Changing the engine oil and filter: The second maintenance will definitely involve changing the engine oil. The oil typically replaced by 4S shops is semi-synthetic, which is of lower quality compared to fully synthetic oil. If desired, you can request fully synthetic oil, though this will require an additional cost. Along with the oil change, the condition of the oil filter will also be checked, and it will be replaced if necessary. 2. Inspecting the engine and other components: The second maintenance will also include checking the engine's working condition, such as whether the pipe connections are normal, if there are any leaks, if the engine sounds normal, or if there are any unusual noises. Furthermore, the vehicle will be lifted to inspect the undercarriage for any scratches or corrosion, as well as to check the braking system, suspension system, and the inner side of the tires to ensure safety for future use.

What does 102H on the tire mean?

The 102H on the tire represents the following: 102 indicates the load index of the tire, corresponding to a maximum single-tire load of 850kg. H represents the speed rating of the tire, with H corresponding to a maximum speed of 210km/h. Below is a detailed explanation of the tire: 1. Tire model identification method, for example, a tire marked as 195/65-R15-88H: 1. Tire width of 195mm. 2. Aspect ratio of the tire section is 65%. 3. Wheel diameter of 15 inches. 4. Load index of 88. 5. Speed rating of H. 2. The maximum load capacity is indicated by the load index. The relationship between common load indices (LI) and actual load values (kg) is as follows: 1. 100 corresponds to a maximum single-tire load of 800kg. 2. 101 corresponds to a maximum single-tire load of 825kg. 3. 102 corresponds to a maximum single-tire load of 850kg. 4. 103 corresponds to a maximum single-tire load of 875kg. 3. Tires are marked with speed limit symbols, represented by letters such as P, R, S, T, H, V, Z, etc., indicating the maximum speed at which the tire can carry the specified load under specified conditions: 1. Q: 160 km/h. 2. R: 170 km/h. 3. S: 180 km/h.
