The tires are not completely straight, but they are close. I have not noticed any drastic changes in ride, but the Blizzaks do have soft sidewalls and don't handle very well at speed. Plus, I like the idea of my tires lasting more than a few thousand miles.

The first picture shows the tire tracks before adjustment. Even though they look even, it is because of the soft nature of the Blizzaks. After adjustment, they still looked the same.
