The phenomenon of a darkish, linear mark showing on a tire after driving with low stress, also known as a “flat tire mark,” outcomes from extreme friction between the deflated tire’s sidewall and the street floor. This friction generates warmth, inflicting the rubber compounds within the tire’s sidewall to degrade and depart a visual discoloration. An analogous mark may seem if a car is pushed with a dragging brake element, although the sample and placement will possible differ. The severity of the mark relies on the space pushed, the tire’s development, and the street floor.
Figuring out this sort of marking could be essential for diagnosing tire and car points. It supplies a visible indicator of a previous deflation occasion, which could in any other case go unnoticed, particularly in circumstances of gradual leaks. This info helps in figuring out the basis explanation for the flat, whether or not it is a puncture, valve failure, or different harm. Understanding the underlying trigger permits for preventative measures to be taken, doubtlessly avoiding future incidents and guaranteeing car security. Traditionally, recognizing these marks has been a necessary a part of car upkeep and inspection.
