Pep Boys used to stock an inexpensive 165R14, but I've been told they don't anymore. Might want to check anyway. If you do get one there, I would recommend having it mounted and ballanced somewhere else though. I bought 2 tires there once that were $25 each for the tires . . . and I owed them over $100 by the time they got them on the car.
I'll dig around and see it I have a used one in better condition than yours, but I doubt I do . . . by the time I pull a tire off you can see the air or a belt has slipped and it looks something like yours.
