If you are noticing any uneven wear on outer edges or center of tread even though you have been diligent in keeping air pressures correct and have not hit a curb with any force or found a mega pothole. Also good idea before purchasing any new set of tires
You should have wheel alignment done on your vehicle annually or whenever your wheels feel to be out of alighment while you're driving. If it's something you can feel that your car is out of alignment it is important to have it looked at and corrected as soon as possible.
you should have a 4 wheel alignment done
Anytime after an accident.
Wheel alignments for vehicles should be performed at any garage and should not be done at home. A special instrument is required for this precision accuracy.
A two wheel can be done, but a four wheel is preferred.

Check your tires. The tread should wear evenly. The steering wheel should not "pull to one side or the other." If either of these is not correct then an alignment is needed.
if you have independent suspention front and rear chances are a 4 wheel alignment can be done typically front wheel drive vehicles but not all.
Alignment rack, need 4 wheel alignment done
Having a wheel alignment done will make your vehicle handle much better. It will also ensure that your tires wear evenly with proper rotation intervals.

Alignments the manufacture suggests every 6 months. I work at a place that does alignments and I only do them if I see irregular tire wear (might be too late at this point), or if the truck pulls, but the alignment could be out and the vehicle goes straight down the road. So there is no Good answer. I would at least get an alignment done when new tires are installed and/or new front end parts are done. Hope this helps.
