The geometric and vehicle center lines are one in the same in a
properly aligned vehicle - shown in
If the rear axle is offset to one side the geometric and vehicle
center lines will be at an angle.
If the rear axle or wheels are toed to one side , the thrust line
will not match up with the center line and the vehicle will pull—in
this case—to the left.
Out-of-alignment conditions occur when the suspension and
steering systems are not operating at their desired angles. Out-of-
alignment conditions are most often caused by spring sag or
suspension wear (ball joints, bushing, etc.) on an older vehicle.
They can also be the result of an impact with a pothole or curb or
a change in vehicle ride height (lowered or raised) on any vehicle
regardless of age. Incorrect alignment settings will usually result
in more rapid tire wear.
CONTROLLING A VEHICLE WHEN TIRE FAILURE OCCURS
If a tire failure occurs, you may hear a loud noise, feel a vibration,
and/or the vehicle may pull toward the side of the failed tire. It is
most important that you. DO NOT BRAKE OR ABRUPTLY TURN
THE STEERING WHEEL. Slowly remove your foot from the
accelerator and hold the steering wheel firmly while steering to
remain in your lane. Once the vehicle has slowed and is fully under
control, apply the brakes gently; safely pull over to the shoulder
and come to a stop. Inspect the tires. If one or more looks flat or
low, shows detachment or other damage, remove tire assembly
and replace it with a properly inflated spare. Bumps or bulges may
indicate detachment within the tire body and require inspection
by a qualified tire technician.
TIRE SPINNING
Spinning a tire to extract a vehicle stuck in mud, ice, snow, or wet
grass can be dangerous. A tire spinning at a speedometer reading
above 35 mph (55 km/h) can in a matter of seconds, reach a
rotation speed capable of disintegrating a tie with explosive force.
Under some conditions, a tire may be spinning at a speed twice
that shown on the speedometer. This could cause serious personal
injury or death to a bystander or passenger. Never spin a tire
above a speedometer reading of 35 mph (55 km/h).
WINTER DRIVING
Tire which meet the U.S. Tire Manufacturers Association definition
of snow tires are marked M/S, M+S, or M&S. On such tires, this
designation is molded into the sidewall. Tires without this notation
are not recommended for winter driving. While All-Season tires are
designed to provide reliable performance in some winter
conditions, the use of 4 winter tires is recommended for optimal
performance. Tires designated for use in severe winter conditions
are marked on at least one sidewall with the letter “M” and “S” plus
a pictograph of a mountain with a snowflake on it.
TIRE STORAGE
Tires should be stored indoors in a cool, dry place. Water should
not be allowed to collect inside them. Tires should be placed away
from electric generators/motors and sources of heat such as hot
pipes. Storage surfaces should be clean and free of grease,
gasoline or other substances which can deteriorate the rubber.
Tires should not be kept on a vehicle if the vehicle is not being
used for a long period of time.
Improper storage can damage your tires in ways
that may not be visible and can lead to a failure resulting in serious
injury or death.
