Alignment after changing wheels?

Im sorry if this is a foolish question, but I took some folks' suggestions and got certain alignment specs done after my suspension work last July.

Well, here we are, May, and Im about to put some different (larger diameter and wider, though not by much) wheels on the car.

How much, if any, will this affect the alignment? Sorry if this is a totally silly question, but I didnt know if another alignment would be in order or not

It won't affect the alignment at all.

It shouldn't affect the alignment at all.  If your alignment is off the larger size might show up sooner.

However when I was a service adviser I'd usually recommend that customers would get their alignments checked every 1-2 years depending on how rough the roads are around them.  A lot of places will do that for free.

It can. Sorta. Streetwise guy informed me after the same question that tires have a pull to them. I had an issue on my Focus swapping snows for all seasons.  I had to swap positions around 3 times before it would track straight.  

So if it seems to pull after the swap, it's not your alignment,  it's the tires themselves. 

Thanks for the input gents
