The same is true for steering the car. As you turn the steering wheel, the steering mechanism will cause the wheels to turn, but once again your tires are at work gripping the pavement and causing the car to follow the angle of the wheels to round a corner.
Another function of your tires is to act as a cushion between you and the rough pavement. Have you ever noticed how smooth your car feels after new tires are installed? That’s because the increased tread thickness of the new tires will absorb and smooth-out the minor cracks, bumps, grooves and pebbles that are on most of our roads.
The life of your tires can be greatly extended by regularly checking the air and keeping them at the specified pressure. Also, your tires should be rotated and balanced every 6000 miles.
