The Importance of Wheel Alignment

The purpose of wheel alignment is to adjust front-wheel handling while driving. If wheel alignment is off, tire life is shortened while car and mileage performance also decrease.

  • Caster

    Caster

    Definition of Caster is the angle created by steering axis and vertical line to the ground when viewed from the side. Caster is positive if the axis is angled backward, and negative if forward. Typically, positive caster will make the vehicle more stable at high speeds.

  • Camber

    Camber

    Definition of Camber is the angle created by steering axis and vertical line to the ground when viewed from the front or rear. If the top of the tire is farther out than the bottom (that is, away from the axle), it is called positive camber; if the bottom of the tire is farther out than the top, it is called negative camber; if the tire stands perfectly vertical, it is called neutral camber.

    With the development of suspension and vehicle technology, most vehicles today have negative camber, which increases outer tire’s contact area and provides stable cornering performance.

  • Toe

    Toe

    Definition of Tod is the angle created by tire direction and vehicle direction when viewed from the upper. If the tire’s front is inward, it’s called Toe-in; if outward, called Toe-out. Too much toe-out usually causes fast wear on tire’s inner surface of tread. And Too much toe-in causes fast wear on outer surface of tread in reverse. Both cases results in worse riding comfort and less fuel efficiency.

When to Check Wheel Alignment

Hankook Tire recommends to inspect wheel alignment every year or for every 20,000km.
The inspection is required
  • After a car accident.
  • After tire replacement.
  • when there is uneven wear on a shoulder.
  • when the steering wheel is unstable and/or vibrating
  • when riding is uncomfortable or fuel efficiency gets worse
