After installing my suspension I never got an alignment. Therefore I have some dramatic camber wear on the tires.

Question 1. If I take my car to a shop for alignment is it recommended that I get new tires before the alignment? Would my current tires with camber wear skew the alignment process?

Question 2. Once alignment is complete am I able to swap between new wheel setups of the same size without having alignment issues?

 

You have toe wear, not camber wear. Anytime ride height is changed, the toe is off and needs to be corrected.

1) It is recommended (and beneficial), but not mandatory, to use good tires during an alignment.

2) Swapping wheels, regardless of size, won't change the alignment at all.
