Ackerman Geometry

The front-end setup that allows a vehicle to steer so that the tires track freely during a turn. During a turn, the inboard wheel on a steer axle has to track a tighter circle than the outer wheel. Ackerman geometry is also known as toe-out during turns and it allows the inner and outer wheels to turn at different angles so that both wheels can roll through a turn without tire scrubbing.
