Proper alignment needs to be maintained in order to preserve both your car’s safety and its tread life. Wheel alignments make sure that all four wheels are consistent with one another and are optimized for maximum contact with the road surface. The wheel alignment is an important suspension-tuning tool that influences the operation of the vehicle's tires. The wheel orientation is broken down to three major components; camber, caster, and toe. Out-of-alignment situations happen when the suspension and steering systems are not operating at their desired angles. They are most times caused by spring sag or suspension wear on an older vehicle. They can also be as a result of entering a pothole, or a change in vehicle ride height on any vehicle regardless of age. Incorrect alignment will rapidly result in more tire wear. Therefore, alignment should be checked whenever new tires or suspension components are installed, and any time strange tire wear patterns are noticed. The alignment should also be checked if the vehicle has had a major road accident.
Alignment Caster is the angle created by the steerings pivot point from the front to back of the vehicle. Caster is always positive if the line is angled forward, and negative if backward. A positive caster ensures the vehicle has more stability at high speeds, and will increase tire lean when cornering. This can also enhances steering effort as well. One good example of positive caster is a motorcycle's front steering forks. The forks point forward at the bottom and slope backward at the top. This backward slope causes the front tire to remain stable when riding straight ahead.
Furthermore, most road vehicles have cross-caster. Cross castered vehicles their caster and camber a bit different which cause it to drift slightly to the right while rolling. This is a safety measure in that un-manned vehicles or drivers who lose steering control will drift toward the side of the road instead of into oncoming traffic. Caster angle settings lets the vehicle manufacturer to balance steering effort, high speed stability and front end cornering efficiency. Vehicles are built with manufacturer’s settings for a reason. An accurate wheel alignment is crucial to balance the treadwear and performance a vehicle's tires deliver. Regular wheel alignments will usually save you as much in tire wear as they cost, and should be considered routine, preventative maintenance.
