While cruising down I-80 from a camping trip in the Sierra Nevadas, the driver of this pickup felt a weird wobble. It didn't feel quite like a flat, but something was definitely wrong with one of the rear tires. He pulled off the main road to see what was wrong and found a huge growth on one of the rear wheels. Moments after pulling out his camera to shoot a short video, the bulge burst and he catches it all on video!
