Safety remains one of the biggest motivators to rotate your tires at routine intervals. Rotating your tires involves moving them from one wheel to another, and helps to ensure that they will wear evenly. Front tires will wear on the outer edges from leans when you turn a curve. The back tires will wear more evenly, but need to be swapped with the front tires to ensure a more even and balanced ride.
Leaving your tires in place will cause you to have to change them more frequently.
