I changed the rears to the exact same ones as before, just new. The fronts still had a LOT of tread left, hence why I didn't change them. I honestly thought I had broken something the first time I took a turn
m3griff had the same experience. See here

It does suck that you have to change all 4 tires anytime you get a bad nail though
