My girlfriend got a flat while she was riding around and didn't realize it until after she rode back to my house. She was probably going about 3 miles on a completely flat rear tire.
I took the tire off and there's 1 pinhole leak in the middle of the tube but the entire sidewall of the tire is chewed up to the point where I can see the steel strands. It's along the entire right side circumference of the tire and appears every 2-3 inches as a spot with massive abrasion or something or another in a spot that's about 1/8" wide along the sidewall.
The tire's probably dead right? And anyone know what might've caused this?
