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 degrade over time with age even
when they are not being used. It is recom-
mended that tires over 6 years generally
be replaced even if damage is not obvious.
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 inflation pressure: the maxi-
mum permissible cold tire inflation pres-
sure 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-
N00939201619
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.
 Groove: the space between two adjacent
tread ribs.
