I knew I was needing tires because of the truck's performance in the rain, and I knew the rear passenger tire was having issues with holding air...and then I found the nice pretty screw driven into it. Fortunately, the place where you air up tires on base is right next to the place you buy tires, so I parked the truck and in I went.

Four hundred dollars. Good thing I wasn't planning to go home this year for Christmas. That would have been too big a chunk. If I'm lucky, they'll get to it tonight, otherwise I get dropped off at work and pick up the truck afterwards.
