Regular lubrication prevents or defers wear to these components. Not only is it important to lubricate the front suspension at correct intervals, but it is also very important to use the correct type of lubricant. This misalignment may be a result of either poor alignment settings or worn parts that create a misaligned front suspension. Tire scrub, a lateral force that pushes the tire sideways, adds to the rolling resistance of the vehicle. As a result, more energy is required to move the vehicle in its intended path of travel.
Unbalanced tires bounce and lose contact with the road.
Underinflating wears out the edges of the tire and adds to tire drag. Fuel is wasted due to increased drag. Overinflation wears the tire in the center. An improperly set camber caused this tire wear.
