Run-flat tires can continue to be driven for 50 to 250 kilometers at a speed of 80 km/h even when the tire pressure is completely lost. Below is more information about run-flat tires: 1. Run-flat tires: Abbreviated as RSC in English. The inflated tire sidewall is the main part that supports the vehicle's weight, especially for tires with a larger aspect ratio (the ratio of tire height to width), where the sidewall is very "thick." 2. Sidewall support: For vehicles equipped with run-flat tires, minor air leaks may go unnoticed by the driver. Therefore, RSC also includes a TPI electronic warning system installed on the wheel rim, which alerts the driver immediately once the tire pressure begins to drop.

How to Park Quickly and Correctly?

To become a parking expert, the first step is to understand the six key lines: the front and rear bumpers, the sides of the vehicle body, and the front and rear axles. The front and rear bumpers and the sides of the vehicle body determine the required parking position, i.e., the safe range; the front and rear axles determine the vehicle's driving trajectory. If you can accurately judge the positions of these six lines from the driver's seat (with a more precise sense), you can not only determine whether the parking space is sufficient but also predict the vehicle's driving trajectory, making parking more efficient. After understanding the six key lines, it's also essential to grasp the principle of a car's low-speed movement. All cars use front-wheel steering, with the rear wheels following the front wheels. The front wheels have greater horizontal capability than the rear wheels. Therefore, the general principle of parking is to first position the rear wheels correctly and then adjust the front wheels.

What are the routine maintenance methods for new energy vehicles?

Routine maintenance methods for new energy vehicles: 1. Correctly grasp the charging time. If the red and yellow lights on the battery gauge illuminate during normal driving, you should charge the vehicle to avoid over-discharging. The charging time should not be too long, as overcharging can cause the battery to heat up and shorten its lifespan. 2. Protect the charger. During the charging process, ensure the charger is well-ventilated; otherwise, it may not only reduce the charger's lifespan but also potentially damage the battery. 3. Maintain sufficient power. After daily use of a new energy vehicle, it is necessary to charge it promptly. If the daily mileage does not exceed 20 kilometers, it is generally recommended to recharge every two days. For daily mileage exceeding 50 kilometers, the vehicle should be charged on the same day to keep the battery fully charged. 4. Cleaning the electric vehicle. Electric vehicles also require timely cleaning. During cleaning, care should be taken to prevent water from entering the charging socket inside the vehicle, ensuring proper waterproofing measures are in place.
