Alignment question + wheels

I am getting my 2 inch lift on this weekend, and I am going to get some cragar soft 8's to go along with it. Here is my question:

- When I get my alignment done, will it make a difference which set of wheels are on the rig? So if it has the stock wheels on it when aligned, and I put the 15x7 soft 8s 4in BS, will the alignment be off, or should I get the new wheels mounted prior to the alignment?

This might be a dumb question, but thought I'd ask the pro's

Not a dumb question.

The answer is it won't matter what wheels/tires you have on when you get it aligned. Wheel/tire size/backspacing doesn't affect the alignment. Changing the height of your suspension does.

thanks for the help
