Tips and Tricks for Tires
Each tire wears differently because of its position on the car. For even wear on all tires, they must be "rotated" or their positions must be swapped regularly. Rule of thumb: you should rotate your tires every other oil change or approximately every 8,000 - 12,000 km.
When tightening the lug nuts of a wheel, make sure to always use a star pattern. This ensures that the wheel is tightly secured and flush against its mount. In a 5 nut wheel, tighten one nut, skip one, tighten the next nut, skip another, and so on until all are tight. On a 4 nut wheel, tighten them in opposing pairs.
Increase tire life 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, go to a NAPA AUTOPRO shop equipped to handle alignment problems and have your alignment adjusted.
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.
