pyöränkulmien

Pyöränkulmien refers to the angles of a vehicle's wheels relative to the road surface and to each other. These angles are crucial for a vehicle's handling, stability, and tire wear. The primary adjustment points are camber, caster, and toe.

Camber is the angle of the wheel's tilt from the vertical when viewed from the front. Positive camber means the top of the wheel is tilted outward, while negative camber means it's tilted inward. Zero camber means the wheel is perfectly vertical.

Caster is the angle of the steering axis from the vertical when viewed from the side. Positive caster means the steering axis is tilted backward, and negative caster means it's tilted forward. This angle influences steering stability and returnability.

Toe, or track, is the angle of the wheels relative to each other when viewed from above. If the front of the wheels are closer together than the back, it's toe-in. If the back of the wheels are closer together, it's toe-out. Correct toe settings are vital for straight-line stability and even tire wear.

These angles are collectively known as wheel alignment or steering geometry. Improper wheel alignment can lead to the vehicle pulling to one side, uneven tire wear, increased fuel consumption, and compromised steering response. Adjustments are typically made by trained technicians using specialized equipment. Regular checks of pyöränkulmien are recommended, especially after hitting potholes or curbs, or if any changes in vehicle handling are noticed.
