With Lafayette's perfect roads it is crucial for your vehicle to be aligned once a year. As your vehicle steers itself into one of many potholes we have, with every jolt to the suspension your alignment numbers move. This is why once a year you should have your vehicles alignement checked. Toe Angle is about 90% of premature tire wear.
