Ran over to the tire dealer to get a new tire, and guess what. They're closed on Mondays. I hate going someplace else, because the road hazard warranty is through them, and these tires aren't cheap.
So, I guess I drive on stupid little spare for another day.
To top it all off, ended up calling the roommate to see if he would mind putting the tire in the back of his pickup. He didn't have a problem with it, since he needed to get up anyway. And he offered to drive me over to the tire place to get the new tire. While we were there, he accidentally drove his truck into a pole and dented his bumper.
I hope this isn't an omen of the week ahead.
