The main angles for wheel alignment

Wheel alignment angles are the relative angles between the vehicle’s chassis components that contribute to the stability of the car’s movement and reduce tire wear. The main wheel alignment angles include: Camber angle, Toe-in angle, Caster angle, and Steering Axle Inclination angle.

Camber Angle

The camber angle is the angle made by the wheel relative to the vertical line when viewed from the front or rear.

• Negative Camber: If the wheel tilts toward the chassis, the angle is considered negative.
• Positive Camber: If the wheel tilts away from the chassis, the angle is considered positive.

Importance of Camber Angle

• Determining contact points and force between the wheel and road: The camber angle directly affects the contact point between the wheel and road, impacting tire grip and wear.
• Reducing uneven wear: Proper camber adjustment distributes the load on the axle, reducing uneven tire wear and preventing excessive bearing wear.
• Compensating for suspension system distortion: The camber angle helps correct angles caused by mechanical distortions in the suspension system or changes resulting from high loads.
• Improving steering stability: Similar to a motorcycle, where the body tilts to define direction, the camber angle helps improve steering stability.
• Enhancing stability during straight-line driving: Together with the Toe-in angle, camber adjustment improves stability during straight-line driving and reduces uneven tire wear.
• Prolonging tire and bearing life: Without camber, wheels may tilt inward under full load, increasing the likelihood of uneven tire and bearing wear. Adjusting the camber angle helps extend the lifespan of both.

The camber angle is one of the primary angles that must be adjusted to achieve vehicle stability and reduce tire wear. Proper adjustment of this angle enhances driving experience and overall vehicle performance.

Toe-in Angle

The Toe-in angle is the angle at which the front wheels tilt when viewed from above. If the front edges of the wheels tilt slightly toward each other, this is called Toe-in, expressed as a positive value. If the edges tilt outward away from each other, it is called Toe-out, expressed as a negative value.

Toe-in Angle Calculation

The total Toe-in value is the sum of the Toe-in angles for each wheel and is defined as the angle between the center lines of the tires.

Importance of Toe-in Angle

• Improving stability during straight-line driving: The Toe-in angle helps compensate for tire tilting inward or outward caused by camber angle and road resistance, ensuring stability during straight-line driving.
