It was one of the drives. The company asked if maybe I could limp it 6 miles up the road so that they didn't have to pay for emergency service to come to me. Well, I did as they said but that caused the bolt to rub the now deflated tire's sidewall until there was a hole there too. lol They had planned to patch it, but that ruined it. So, they threw on my spare. I'm not sure how much the emergency service would've cost, but the tire is about $300. *This* is why I'm not an O/O.
