New rear tire or both new tires?

[Whoops]

Well thanks for the input all. I know the back tire isn't as critical as the front, but since the way the staple went in, I feel like it probably isn't worth the risk and am going to replace the back tire for sure. Not so sure about the front though since it still looks like new. If there was any signs of cracking on the sidewalls I would just go all in and replace them both.

The OCD in me is going to go bonkers with mismatched tires though.
