Can someone r/explainlikeimfive what rotating tires is about?

You swap them around the car so the tread wears more evenly (for example moving the front drivers side tire to the front passenger side, and the front passenger side to the rear etc).  Otherwise the tires will wear unevenly which could cause them to wear out prematurely.
