What's eating this tire?Not according to the editors of Real Answers, a Bridgestone-Firestone USA publication, where this photo originally appeared. The termite-damage-like crevices here are the result of extreme voltage, “electricity that ‘burrowed’ through this tire” when a boom truck hit a high wire and the electricity made its way through the frame on its way to the ground, wrote Real Answers editors. If you think of rubber as the ultimate insulator, think again, they added. “Even insulators will conduct electricity if the voltage is high enough.” (The operator walked away from this incident unharmed.)
