Tire yellowing may be caused by metal rust, dust, and oxidation of tire wax. Here are detailed explanations for these three phenomena: Metal rust: Brake pads contain iron, and when braking, the wear on the brake pads produces iron powder. Over time, this powder rusts and turns yellow, causing the tires to appear yellow. Dust: When driving through muddy areas, the tires pick up dust. If not cleaned for a long time, the dust can discolor the tires, making them difficult to clean and eventually turning yellow. Tire wax oxidation: To protect the tires, a layer of wax is applied to the surface. However, the wax can melt in high temperatures, sticking to the tires. Over time, severe oxidation occurs, leading to yellowing of the tires.

How to Escape When a Car Falls into Water?

When the car first falls into the water, do not panic inside the vehicle. Quickly identify your position and determine the escape route and plan. During the process of the car entering the water, since the front of the car is heavier, try to escape from the rear seats. If it is a bus, escape directly from the nearest or the highest window. If neither the window nor the door can be opened, press your face as close as possible to the upper part of the car roof, wait for the water to slowly pour in through the gaps of the car, and use a window-breaking hammer to shatter the window glass.
