“Ballooning” refers to a phenomenon that occurs when tires, particularly those on high-performance or RC (radio-controlled) vehicles, rotate at very high speeds. As the tires spin faster, centrifugal force causes the rubber of the tire to expand outward, making the tire appear to “inflate” or “balloon.” This happens because the forces acting on the tire pull it away from the wheel, stretching the rubber material. In extreme cases, this can alter the tire’s contact with the ground, affecting grip
