Why Do New Tires Have Colored Dots on Them

Have you ever noticed the small colored dots on brand-new tires and wondered what they mean?

Most people assume they're random factory markings, but these tiny paint dots actually play an important role in tire engineering. In this episode of History of Simple Things, we explore the surprising reason tire manufacturers use yellow and red dots, how they help reduce vibration, and why such a small detail can make a big difference in ride quality. Discover the history, science, and precision manufacturing behind one of the most overlooked features on modern tires.
