It is important to familiarize yourself with the following terms:
Cold tire pressure: • The measured pressure after the vehiclehas been parked for at least three hours, or • The measured pressure when the vehicleis 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 c
ontains a whitewall,
bears white letteri
ng 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 si
dewall of an asym-
metrical tire that has a particular sidethat 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 rati
ng (GVWR) of 10,000
pounds or less.
Light truck (LT) tire
: a tire designated by
its manufacturer as primarily intended foruse on lightweight tr
ucks or multipurpose
passenger vehicles. Tread: portion of a tire that comes into contact with the road. Tread rib: a tread se
ction 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 line
ar 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 tirebeads are seated. Rim diameter: nominal diameter of the bead seat.
Check to see that the battery is securely installed and cannot be moved. Also checkeach terminal for tightness. If you will not be driving your vehicle for a long period of time, remove the battery andstore 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
WA R N I N GDriving with tires that are worn, damaged or improperly inflated is dangerous. These type tire conditions will adverselyaffect vehicle performance. These type tire conditions can also cause a tread separation or blowout which mayresult in an accide
nt causing serious
injury or death. Tires, including spar
e tire, degrade over
time with age even when they are not being used. It is recommended that tires over 6 yearsgenerally be replaced even if damage is not obvious.NOTE
