What Causes Tire Reddening?
2 Answers
There are many possible causes for the reddening. It is recommended to have it checked at a 4S shop. Below is a detailed introduction about the functions of car tires: 1. Enabling driving and other operations: Tires serve as the medium for transmitting forces between the vehicle and the road surface, transferring driving force, braking force, steering force, etc., thereby enabling driving, braking, steering, and other operations of the vehicle. 2. Supporting vehicle load: The load of the vehicle causes the tire to sink until the average pressure of the tire's contact area balances with the internal inflation pressure of the tire. 3. Reducing and absorbing vibrations and impacts during driving: This prevents early damage to vehicle components caused by severe vibrations. At the same time, it adapts to the high-speed driving state of the vehicle and reduces driving noise, ensuring driving safety, comfort, handling stability, and fuel economy.
After driving for so many years, I've encountered the issue of tires turning red quite a few times. The most common cause is brake pad dust from the road, especially those copper-containing brake pads. The dust sticks to the tires and turns red when washed by rain. Additionally, the humid weather in southern regions accelerates rubber aging, and oxidation deepens the color. My car, often driven in Guangdong, frequently experiences this. The solution is simple: regular car washing. Use water or neutral detergent to clean the tire surface, avoiding strong chemical cleaners that can damage the rubber. If the color doesn't fade, it might indicate internal aging issues, so check for cracks or reduced grip. For prevention, I recommend avoiding dusty roads and choosing low-dust brake pads when replacing them, which can make the tires last longer.
