New tires = -$$$
I somehow managed to puncture the sidewall of my front left tire. Not repairable. I have a full size spare, but it's got significantly more tread than the other tires, and on an AWD vehicle, that's not a good thing. I could buy one new tire so I had two with matching tread depth, but the tires I've got on there right now are discontinued and unavailable. Sooo, once again I have to buy a whole new set of tires.
