I'm certainly no expert, but I would be looking at camber. My car has had inside edge wear since new and I'm certain it is from excessive neg. camber. If you just bought the car, the wear was probably there when you bought it and you didn't notice. You really have no way of knowing what went on before you got it. I suggest you get a wheel alignment and check the suspension before you install your new tires.
