No, they do not. They'll mount and balance them for you. That's it.
Nobody just "does it." A wheel alignment can be a breeze if nothing is out of spec, however, if something has been damaged or is just plain worn out you, will generally see the abnormal wear on the tire indicating that there is a problem. It surely isn't a free process to put the vehicle on the rack and get it all set up to check, it takes time, and time is money. I recommend everyone get their alignment checked at the very least once a year, or if you encounter ANY hard hit potholes, driving problems, such as pulling to one side or the other, vibrations going down the road, unusual tire noise when cornering etc. The geometry of all the steering components is critical to proper tire wear as well as safe handling/driving going down the road. Regular inspections can prevent something like a catastrophic tire failure, or other steering linkage failure that can result in a crash, serious personal injury or even death. I am a retired professional journeyman mechanic of 30 years, and since I can't do the work anymore, I will take my car to a place that has a properly trained, properly certified, and experienced mechanic. Remember, you get what you pay for, so the guys down on the corner that will " check it out" for a fraction of the cost, usually are not certified, just glorified shade tree mechanics. Just saying, its you and our families lives at stake. Save a buck now on labor, you may pay dearly for it later. Happy thanksgiving!
