Wheel Alignment: Explained

The process of tyre rotation is important to improve their durability and maintain consistent wearing of each tyre. It is necessary to rotate them from one position to another.

When you look at the wheels, they might seem to be properly aligned. However, they could be misaligned in reality. You need to have proper information about wheel positioning methods to figure this out, and being familiar with such strategies would be quite useful.

Principles of wheel alignment:

Below are the principals involved in attaining proper wheel alignment:

Toe-in and toe-out

Toe is an angle that can be determined from the top of the car by drawing a straight line along the horizontal middle of each wheel compared to the centerline of the car. When all front wheels are in place, the toe will be zero. If the wheels face each other, it’s a toe-in. Toe out is when they’re facing outwards. To boost the lifespan of the tyre, what you need to do is fix the toe angle.

Positive and negative camber angles

It is the degree of inclination of the wheel which is calculated from the front side of the car. The wheel inclined towards the piston is considered the negative angle of the camber. Whereas, a wheel inclined outward is considered a positive angle of camber. Right wheel camber increases tyre life and reliability and reduces tension on suspension components.

Positive and negative caster angles

The caster angle is the inclination between the lines traced along the steering axis and the vertical line as seen from the sides of the car. If the axis is tilted back at the top, the angle is a positive caster. If it’s inclined left, it’s considered a negative caster. The angle of the caster improves stability and improves cornering.

Chassis height

Often vehicle owners get the height of their vehicle chassis increased for greater road clearance. It might be counterproductive for the tyre’s life if the chassis height doesn’t meet the manufacturer’s specification. The reason for this is that altering the height doesn’t only change the height of the vehicle; it also alters the toe, caster, and camber angles. If the chassis height is out of specification, it can contribute to poor handling of the vehicle and lead to tyre wear.

Turning radius

While taking a curve, the steering arms enable the front wheels to turn at different angles. If both wheels turn at the same angle, the outer wheel suffers severe wear. To avoid this, the turning radius of the inner wheel must always be greater than that of the outer wheel.

Steering axis inclination

It’s also known as the Kingpin inclination. It allows the wheels to return to the normal straight-up location while bearing the load. It also increases stability under the conditions of braking. Similar to the angle of the camber, the inclination of the steering axis is calculated from the top.
