4 wheel alignment
 

Do i need to have my 31's on for the alignment or can i add them after the alignment? Was planning on hitting up the tire shop after i get the alignment done...

Adding tires does not change your steering in any way so no need for an alignment.

just get em balanced before you put them on.

Im installing my lift as we speak, so im getting the alignment done monday morning and hitting up the tire shop to get the rims mounted and balanced. It sounds like it doesnt matter if I get it aligned first or not though...
