What are the key wheel alignment parameters and their effects?

Key alignment parameters are: Camber (wheel tilt from vertical) affects tire wear and cornering grip. Toe (pointing inward or outward) affects straight-line stability and tire wear. Caster (steering axis tilt) provides self-centering and stability. Proper alignment ensures even tire wear, stable handling, and good steering feel. Misalignment causes uneven tire wear, pulling, and poor handling.
