What does tire buffing mean?

Buffing a tire refers to the process of grinding off the white barcode on the tire's bead area. A tire with its trademark removed is not a genuine product. These tires are usually identified as problematic during factory inspections. Some may still be usable, but they are not covered by the three-guarantee policy, meaning the manufacturer will not be responsible for any issues that arise. Essentially, these are substandard tires. Tires are one of the most critical components of a vehicle, directly contacting the road surface and working in conjunction with the suspension system to absorb shocks during driving, ensuring ride comfort and smoothness. They also provide excellent traction between the wheels and the road, improving the vehicle's acceleration, braking, and off-road capabilities. Additionally, tires bear the weight of the vehicle, making their role in automotive performance extremely important. Most buffed tires are those that failed dynamic balance tests, though other aspects may appear normal. While these tires do not pose an immediate risk of blowouts, they are not recommended for frequent high-speed driving (or speeds below 60 km/h). Although blowouts are unlikely, the abnormal dynamic balance can cause noticeable vibrations in the car (especially at high speeds) and even steering wheel shaking, which can compromise driving safety. For daily tire maintenance, pay attention to the following points: Regularly inspect the tire surface for cracks, deformations, or other defects. As tires wear down, the tread grooves gradually become shallower. If the tread is completely worn out, the tire loses its ability to drain water and provide traction, significantly reducing the vehicle's performance. Small cracks may also become potential hazards for blowouts at high speeds. Additionally, promptly remove any stones stuck in the grooves. Park on flat surfaces whenever possible and avoid parking on roads with thick, sharp, or jagged stones. Do not park near or in contact with oil products, acids, or other materials that can deteriorate rubber. After parking, avoid turning the steering wheel, as this accelerates tire wear. Do not splash water to cool overheated tires. In hot weather or during high-speed driving, tires can overheat, increasing internal pressure. In such cases, park to allow the tires to cool naturally. Never release air to reduce pressure or splash water to cool the tires, as this can cause abnormal aging of the tread rubber. Avoid sudden braking whenever possible, as frequent or hard braking can accelerate tread wear due to dragging against the road surface.

Can You Pick Up or Drop Off Passengers While Waiting at a Traffic Light?

It is not allowed to stop and pick up or drop off passengers at intersections with traffic lights. Reason: Whether there are traffic lights or not, stopping to pick up or drop off passengers is considered illegal. This is because stopping within 50 meters of an intersection is prohibited for such purposes. Precautions: When stopping at a red light, if your vehicle is the first in line, it is advisable to maintain a slightly larger distance from the stop line. This ensures you do not run the red light and provides enough space to start moving when the light turns green. If there are already many vehicles waiting in line, try to keep a sufficient distance from the vehicle in front. This ensures safety (preventing the vehicle in front from rolling back) and allows enough time and distance to observe the movement of the vehicles ahead, ensuring a smooth start.

What are the items included in a vehicle's second maintenance?

The second maintenance for a new vehicle requires replacing the engine oil and oil filter, along with inspecting various fluids and components, including tires and the chassis. The items for the second maintenance are essentially the same as those for the first maintenance: The second maintenance for a new vehicle requires replacing the engine oil and oil filter, along with inspecting various fluids and components, including tires and the chassis. The items for the second maintenance are essentially the same as those for the first maintenance. Items to be checked during the second maintenance: Check that the steering free play and toe-in meet the required standards, ensuring the steering is light, flexible, and reliable, with no lateral wobble or deviation of the front wheels during driving. Inspect the transmission, drive axle, or half-shaft drive mechanism for proper lubrication, secure connections, absence of abnormal noise or overheating, smooth gear shifting without jumping or oil leakage. Verify that the brake pedal free travel and brake clearance meet specifications, ensuring the service and parking brakes function properly without deviation or dragging during braking, with the inertia proportioning valve operating normally and no oil leakage.
