2E-4 TIRES AND WHEELS
Caster is the tilting of the uppermost point of the
steering axis either forward or backward from the
vertical when viewed from the side of the vehicle. A
backward tilt is positive and a forward tilt negative.
Caster influences directional control of the steering but
does not affect tire wear.
Weak springs or overloading a vehicle will affect
caster. One wheel with more positive caster will pull
toward the center of the car. This condition will cause
the car to move or lean toward the side with the least
amount of positive caster. Caster is measures in
degrees and is not adjustable.
The condition of driving a vehicle fast on the road
surface covered with water can cause tires to fail to
rotate with a good contact on the surface, so results in
remaining them a float. This is so-called hydroplaning.
It causes brake failure, lower tractive force and losing
the steering performance so it is very vulnerable
condition.
WHEEL ALIGNMENT
The first responsibility of engineering is to design safe
steering and suspension systems. Each component
must be strong enough to with stand and absorb
extreme punishment. Both the steering system and
the front and the rear suspension must function
geometrically with the body mass.
The steering and suspension systems require that the
front wheels self-return and that the tire rolling effort
and the road friction be held to a negligible force in
order to allow the customer to direct the vehicle with
the least effort and the most comfort.
A complete wheel alignment check should include
measurements of the rear toe and camber.
Toe-in
Toe-in is the turning in of the tires, while toe-out is the
turning out of the tires from the geometric centerline or
thrust line. The toe ensures parallel rolling of the
wheels.
The toe serves to offset the small deflections of the
wheel support system which occur when the vehicle is
rolling forward.
The specified toe angle is the setting which achieves-
degrees “0¡Æ” of toe when the vehicle is moving.
Incorrect toe-in or toe-out will cause tire wear and
reduced fuel economy. As the individual steering and
suspension components wear from vehicle mileage,
additional toe will be needed to compensate for the
wear. Always correct the toe dimension last.
Camber
Camber is the tilting of the top of the tire from the
vertical when viewed from the front of the vehicle. When
the tires tilt outward, the camber is positive. When the
tires tilt inward, the camber is negative. The camber
angle is measured in degrees from the vertical. Camber
influnces both directional control and tire wear.
If the vehicle has too much positive camber, the
outside shoulder of the tire will wear. If the vehicle has
too much negative camber, the inside shoulder of the
tire will wear. Camber is measured in degrees and is
not adjustable.
