(5) Rim Diameter:Diameter of
the wheel in inches.
(6) Service Description
:These
characters represent the load
index and speed rating of the
tire. The load index represents
the load carrying capacity a tire
is certified to carry. The speed
rating is the maximum speed a
tire is certified to carry a load.
Light Truck (LT-Metric) Tire
(1) Light Truck (LT-Metric)
Tire
:The United States version
of a metric tire sizing system.
The letters LT as the first two
characters in the tire size mean
a light truck tire engineered to
standards set by the U.S. Tire
and Rim Association. (2) Tire Width
:The three-digit
number indicates the tire section
width in millimeters from
sidewall to sidewall.
(3) Aspect Ratio
:A two-digit
number that indicates the tire
height-to-width measurements.
For example, if the tire size
aspect ratio is 75, as shown in
item 3 of the light truck
(LT-Metric) tire illustration, it
would mean that the tire's
sidewall is 75 percent as high as
it is wide.
(4) Construction Code
:A letter
code is used to indicate the type
of ply construction in the tire.
The letter R means radial ply
construction; the letter D means
diagonal or bias ply
construction; and the letter B
means belted-bias ply
construction.
(5) Rim Diameter
:Diameter of
the wheel in inches.
(6) Load Range
:Load Range. (7) Service Description
:The
service description indicates the
load index and speed rating of a
tire. If two numbers are given as
in the example, 120/116, then
this represents the load index for
single versus dual wheel usage
(single/dual). The speed rating is
the maximum speed a tire is
certified to carry a load.
Tire Terminology and
Definitions
Air Pressure:The amount of
air inside the tire pressing
outward on each square inch of
the tire. Air pressure is
expressed in kPa (kilopascal)
or psi (pounds per square inch).
Accessory Weight
:The
combined weight of optional
accessories. Some examples of
optional accessories are
automatic transmission, power
windows, power seats, and air
conditioning.

304 Vehicle Care
terminal if the vehicle has one.
Do not let the other end touch
metal. Connect it to the
positive (+) terminal of the good
battery. Use a remote
positive (+) terminal if the
vehicle has one.
7. Now connect the black negative (−) cable to the
negative (−) terminal of the
good battery. Use a remote
negative (−) terminal if the
vehicle has one.
Do not let the other end touch
anything until the next step.
The other end of the
negative (−) cable does not go
to the dead battery. It goes to a
heavy, unpainted metal engine
part or to a remote negative (−)
terminal on the vehicle with the
dead battery. On your van, use
the unpainted radio antenna
bracket as a remote
negative (−) terminal.
8. Connect the other end of the
negative (−) cable to the
negative (−) terminal location
on the vehicle with the dead
battery. On your van, use the
unpainted radio antenna
bracket as a remote
negative (−) terminal.
Caution
The vehicle uses the unpainted
radio antenna bracket as a
remote negative (-) terminal.
Move the antenna coaxial cable

out of the way before clamping
the negative jumper cable to the
fixed antenna bracket. Avoid
touching the negative cable clamp
to the air conditioning line. Failure
to do either of these could
damage the vehicle. The repairs
would not be covered by the
vehicle warranty.
9. Now start the vehicle with the good battery and run the
engine for a while.
10. Try to start the vehicle that had the dead battery. If it will not
start after a few tries, it
probably needs service.
Caution
If the jumper cables are
connected or removed in the
wrong order, electrical shorting
may occur and damage the
