I don't know how we can suggest replacing tires without seeing them. If the tires have good tread and in good shape, fix the puncture and put it back on.

You don't throw away my car when I get a flat, so don't automatically throw away a tire when it gets punctured. The tire store can fix a flat for usually 5 or 6 bucks including putting it back on the ground where it came from.

Good luck,
