The best time to check tire pressure is when the tires are cool. Have your tires rotated and balanced regularly. Rotating the tires is a way to get more even wear of the tires. The owner s manual, again, will give the recommended rotation period and pattern for rotation. If the tire is unbalanced, you will have vibration when you re driving the car and uneven tire wear.
Proper alignment is also important to prevent uneven tread wear.
Turn the air conditioner on for a few minutes every week during the cool months. This will keep the system lubricated. Make a habit of checking weekly to be sure your lights and signals and horn all work properly. Get to a service station and have it checked. Proper preventative maintenance will keep you several steps ahead of major car repair.
