The Benefits of Wheel Alignment. Proper wheel alignment is extremely important to protect tire investment and tire life, maximize fuel economy and stop safely in wet weather conditions. Proper wheel alignment helps vehicles hold the road better and feel more stable.
Another difference between rims and wheels is how they operate; a wheel is a round device that rotates to allow a vehicle or other heavy equipment to move.

The rotating motion moves the vehicle forward or backward, depending on which direction the wheel rotates.
