It is in no way necessary to have an alignment done when tires are replaced.

However, it is a good practice to get the car aligned at a regular interval to ensure everything is up to snuff. I get mine done in late spring, right after pothole season and just before the track season starts. I also recommend getting a "good" alignment done in a shop that will take the time to go back and forth between setting to get all the parameters as close to nominal as possible and not just within tolerance. The factory tolerances on the F8X are quite wide and a good alignment makes a significant difference on how well planted the car feels.
