The Nissan Path

So I would like to switch back and forth between two sets of tires. I have two sets of the stock 16 wheels


I am looking to but a new set of tires for one of the wheel sets. If one set of tires is 265 75 16 what I currently own, and other is LT 285 75 16 , what I want to buy, should I be concerned about realignment each time ,when I swithch?

When does it really matter? If i was using different wheels on each?

The swap to different size tires are not going to change the wheel alignment, however, many will suggest that if you are installing new tires, a wheel alignment should be performed.
