It's time for me to replace the tires on my 2016 4Runner with 64K miles, and I noticed on the tire shop's web site that they offer 4-wheel alignment as an additional service for $69 when buying a new set of tires.
Does a 4-wheel alignment actually do anything useful on an undamaged vehicle? And is it advisable to do it routinely when replacing tires? I've not noticed any symptoms of misalignment such as vibrations or pulling to one side. I do notice, however, that the front wheels are significantly more worn on the inside tread than outside. Is that a symptom of misalignment?
