What Causes Yellowing of Tires?
1 Answers
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.
