The minor imperfections of new tires are comparable to the fine irregularities seen on motorcycle tires: they catch the eye at first glance, but have no impact on performance. These small imperfections visible on new tires are actually the result of a specific manufacturing process and do not alter their performance in any way.
A by-product of manufacturing:
To understand the origin of these small bumps, imagine the manufacturing process of tire molds. These molds are designed with many small holes that allow air to escape during the curing of the rubber. This prevents the formation of air bubbles inside, which could weaken the tire. When liquid rubber is injected into these molds, the air and thin layers of rubber are expelled through these openings, creating the small bumps we see.
The answer is simple: they have no specific function. Their role is limited to the manufacturing process, ensuring uniform
