I'd get an alignment after changing struts, or any of the major suspension components.
Even despite Michigan roads, none of our cars get any kind of yearly alignment and have no issues with being misaligned. Unless you hit something so big (which will likely cause other kinds of damage), that suspension really isn't going to move out of alignment.
I do rotate tires on a regular basis on our vehicles, though. Most of the time it works out perfectly with having all-seasons for spring/summer/fall and winter tires for, well, winter. Generally the mileage put on during the winter is right around enough for me to be able to rotate them when I install them the next time. The all-seasons generally require a rotation sometime before taking them off, depending on vacations/extra driving.
