How to Distinguish Run-Flat Tires from Regular Tires?

Methods to distinguish run-flat tires from regular tires are: 1. Check for markings on the appearance: Run-flat tires have run-flat markings, while regular tires have no markings; 2. Press the tire sidewall: Run-flat tires have thick sidewalls, while regular tires have thin sidewalls. The functions of tires are: 1. Transmit driving force, braking force, and steering force to achieve vehicle operation; 2. Support vehicle load; 3. Reduce and absorb vibrations and impacts during driving, avoiding severe vibrations that could damage vehicle components. Tire maintenance methods include: 1. Regularly check tire pressure; 2. Remove debris from tire treads; 3. Inspect tire wear and replace them promptly based on wear conditions; 4. Perform four-wheel rotation—when the vehicle pulls to one side or exhibits abnormal steering, rotate the tires promptly. Four-wheel rotation ensures even force distribution on all tires, preventing excessive wear.

I remember when I bought my last car, the salesperson taught me the easiest way to distinguish run-flat tires from regular tires is to check if there's an RFT or Run-Flat marking on the tire sidewall. Run-flat tires have particularly thick sidewalls that feel very firm when pinched, while regular tires are much softer, like a big pillow. Run-flat tires also have star-like symbols or specific trademarks on the sidewalls, whereas regular tires only have clean specifications. Price-wise, run-flat tires are significantly more expensive, but they allow you to drive 50-80 kilometers after a puncture, whereas regular tires leave you stranded immediately. My friend's car had a run-flat tire, and once it was leaking air, he still managed to drive safely to the repair shop—this feature is incredibly practical. Nowadays, repair shops often try to trick me into switching to regular tires to save costs, but I always check the sidewall markings to avoid being fooled. I recommend feeling the tires when buying them—the difference in texture is obvious.

What Does On-Demand Four-Wheel Drive Mean?

On-demand four-wheel drive refers to a system that automatically activates four-wheel drive when the vehicle encounters conditions requiring it, otherwise operating in two-wheel drive mode. Automotive four-wheel drive systems are categorized into full-time four-wheel drive, part-time four-wheel drive, and on-demand four-wheel drive. On-demand four-wheel drive does not require driver intervention. When poor road conditions or wheel slippage are detected, the system automatically engages and redistributes engine torque to the front wheels, seamlessly switching to four-wheel drive. Compared to other four-wheel drive systems, on-demand four-wheel drive has a simpler structure, effectively reducing costs and overall vehicle weight. It is suitable for those needing moderate off-road capability while maintaining fuel efficiency. Precautions for using on-demand four-wheel drive systems: The vehicle will automatically switch from two-wheel drive to four-wheel drive when detecting wheel slippage, active steering, or loss of control. Alternatively, the driver can forcibly engage four-wheel drive via a lock switch, though this method has specific requirements. For example, in the Toyota Highlander, the four-wheel drive mode can only be maintained at speeds below 40 km/h after locking. Some part-time four-wheel drive vehicles cannot use four-wheel drive on hard surfaces, especially when turning, due to the lack of a center differential in the transfer case, which prevents adjustment of front and rear axle speeds.

What is the most effective way to clean a three-way catalytic converter?

The most effective method to clean a three-way catalytic converter is disassembly cleaning, although it is more labor-intensive and time-consuming. This process involves completely removing the three-way catalytic converter from the vehicle, soaking it in a cleaning agent (such as oxalic acid or toilet cleaner) for a period of time, and then rinsing it with clean water. The three-way catalytic converter is an important external purification device installed in the automobile exhaust system. It converts harmful gases such as carbon monoxide, hydrocarbons, and nitrogen oxides emitted by vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. The three-way catalytic reactor resembles a muffler, with its exterior made of double-layer stainless steel thin plates forming a cylindrical shape. Between the double-layer thin plates, there is an insulating material—asbestos fiber felt. Inside, a purifying agent is placed between the mesh partitions.

What to Do If a Novice Driver Loses 15 Points in One Day?

You can handle electronic monitoring violation records of 1, 2, or 3 points through the Traffic Management 12123 app, reducing the total points deducted to below 12. Others can wait until the probationary period of their driver's license is over to process the violations. If there is an electronic monitoring ticket that deducts 12 points at once, it also needs to wait until the probationary period is over to be processed. This way, the license will not be revoked, and you only need to retake the theory test (Subject 1). If it's just an electronic monitoring ticket, you can register the vehicle under a family member or friend's driver's license to handle part of the violations, and then use your own license to process the remaining violations. If a driver's license accumulates 12 or more points within a single scoring cycle, the driver must report to the traffic management department of the public security authority at the place where the license was issued or where the violation occurred within 15 days. They must attend a seven-day course on road traffic safety laws, regulations, and related knowledge. Notes on handling violations: One driver's license can only process violations for up to three vehicles, and one vehicle can only be processed by up to three driver's licenses. If a vehicle is recorded with a 12-point deduction at once, a probationary driver's license cannot be used to handle it. Instead, a license that has passed the probationary period can be used to assist in processing, avoiding license revocation. Tickets issued by traffic police on-site or those captured by high-definition cameras showing the driver's face cannot be processed using another person's driver's license; only the violator's own license can be used. This is because the traffic police department will conduct facial recognition to verify the identity of the violator.

Can I still drive if the low tire pressure warning light comes on?

If the low tire pressure warning light comes on, you should not continue driving. Immediately reduce your speed, avoid sharp steering and sudden braking, then stop to check the tires. When the tire pressure warning light illuminates, there are typically four possible causes: 1. The tire has been punctured; 2. The tire pressure is too high; 3. Driving with low tire pressure for an extended period; 4. A malfunction in the tire pressure sensor. If the tire pressure warning light comes on while driving, first turn off the engine, wait 1 to 2 minutes, then restart the vehicle. After the vehicle stabilizes, check the tire pressure values displayed on the dashboard. Both insufficient and excessive tire pressure can trigger the warning light. You can slowly drive to an auto repair shop or detailing shop to adjust the tire pressure. If you have a personal inflation device, you can adjust the pressure yourself.

How to Make a U-turn at Traffic Lights Intersection?

Making a U-turn at traffic lights intersection: 1. U-turns are allowed at intersections with U-turn signs; 2. U-turns are allowed at intersections without U-turn lights but with left-turn lights; 3. If there is no U-turn indicator or no U-turn prohibition sign at the intersection, vehicles can make a U-turn at any time without affecting other vehicles and ensuring safety; 4. U-turns are allowed in yellow grid areas. Parking is strictly prohibited in areas with yellow grid lines. When the traffic light ahead is red, vehicles behind should avoid stopping in this area, but as long as there is a central guardrail, U-turns are allowed in this area; 5. U-turns are prohibited in zebra crossing areas.
