Increase the life of your tires by making sure your wheels are in alignment. Wheels will go out of alignment under normal driving conditions, but this will be accelerated by excessively running into bumps and curbs. If you are experiencing uneven tire wear, schedule an appointment to have your alignment adjusted.
Each tire wears differently because of its position on the car. To ensure even wear on all tires, they must be “rotated”—their positions must be swapped regularly. A good rule of thumb: you should rotate your tires every other oil change or approximately every 5,000−8,000 miles.
For best performance and longest life, keep your tires properly inflated based on the manufacturers specifications (32 psi on average). Overinflation causes excessive wear down the center of the treads while underinflation causes excessive wear at the edges. You can usually find the proper inflation level on the inside of the driver’s side door of your car.
