People are just realizing the spikes on tires are not for decoration

Answer: The small spikes found on motorcycle tires, known as vent spews, are a by-product of the tire manufacturing process

Tire molds typically include multiple small vents to allow air bubbles to escape, which helps prevent the formation of air bubbles inside the tire. As a result, both the air bubbles and some melted rubber exit through these vents, leading to the creation of vent spews.
