I am a stickler about handling and having good tires but I don't like to spend tire money for no logical reason. I am not about to throw 2 tires away that have thousands of miles of wear left. I have never replaced perfectly good tires even when I have changed brands and I have no idea how to wait until the other two are worn out when two already need replacement.

I say it doesn't matter what amount of tread your good tires have. If they are good tires there is no need to replace them. You will be fine buying just two if those purchased are a close match to what you have. Just because you are buying used tires it doesn't mean you are making your X a safety hazard.

What tires will you be keeping and what tires are you thinking of buying-- as it relates to brand, model, size and rating?
