balance and alignment is different.

balancing is mandatory when changing tire.  but drifting a one side needs alignment, not balancing. 

Google balancing/alignment difference. 

Esp. if you only change one tire, the new tire and old tire on the other side might have different wear resulting one tire bigger than the other.   This is why you need new alignment.
