It is important to familiarize yourself with the
following terms:
Cold tire pressure:
• The measured pressure after the vehicle
has been parked for at least three hours,
or
• The measured pressure when the vehicle
is driven less than 1 mile (1.6 km) after
having been parked for three hours.
Maximum pressure: the maximum per-
missible cold tire inflation pressure for
this tire.
Recommended inflation pressure: the
inflation pressure for optimum tire perfor-
mance.
Intended outboard sidewall:
• The sidewall that contains a whitewall,
bears white lettering or bears manufac-
turer, brand, and/or model name molding
that is higher or deeper than the same
molding on the other sidewall of the tire,
or
• The outward facing sidewall of an asym-
metrical tire that has a particular side
that must always face outward when
mounted on a vehicle.
Passenger car tire: a tire intended for use
on passenger cars, multipurpose passen-
ger vehicles, and trucks that have a gross
vehicle weight rating (GVWR) of 10,000
pounds or less.
Light truck (LT) tire: a tire designated by
its manufacturer as primarily intended for
use on lightweight trucks or multipurpose
passenger vehicles.
Tread: portion of a tire that comes into
contact with the road.
Tread rib: a tread section running circum-
ferentially around a tire.
Tread separation: pulling away of the
tread from the tire carcass.
Carcass: the tire structure, except tread
and sidewall rubber which, when inflated,
bears the load.
Sidewall: portion of a tire between the
tread and bead.
Section width: the linear distance between
the exteriors of the sidewalls of an
inflated tire, excluding elevations due to
labeling, decoration, or protective bands.
Bead: the part of the tire that is made of
steel wires, wrapped or reinforced by ply
cords and that is shaped to fit the rim.
Ply: a layer of rubber-coated parallel
cords.
Cord: the strands forming the plies in the
tire.
Rim: a metal support for a tire or a tire
and tube assembly upon which the tire
beads are seated.
Rim diameter: nominal diameter of the
bead seat.
Check to see that the battery is securely
installed and cannot be moved. Also check
each terminal for tightness.
If you will not be driving your vehicle for a
long period of time, remove the battery and
store it in a place where the battery fluid will
not freeze. The battery only should be stored
with a full charge.
Before cleaning the battery, tighten all the
filler port caps to keep dirt and moisture out.
Tires
WARNING
Driving with tires that are worn, damaged
or improperly inflated is dangerous.
These type tire conditions will adversely
affect vehicle performance.
These type tire conditions can also cause a
tread separation or blowout which may
result in an accident causing serious
injury or death.
Tires, including spare tire, degrade over
time with age even when they are not
being used.
It is recommended that tires over 6 years
generally be replaced even if damage is
not obvious.
