Light Truck (LT‐Metric) Tire
(A) 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.
(B) Tire Width
:The three‐digit
number indicates the tire section
width in millimeters from
sidewall to sidewall.
(C) 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 C 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.
(D) 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.
(E) Rim Diameter
:Diameter of
the wheel in inches.
(F) Load Range
:Load Range.
(G) 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
steering, power brakes, power
windows, power seats, and air
conditioning.
Aspect Ratio
:The relationship
of a tire's height to its width.

Vehicle Care 10-95
remain on the surface being
cleaned for extended periods
of time.
Cleaners may contain solvents that
can become concentrated in the
interior. Before using cleaners, read
and adhere to all safety instructions
on the label. While cleaning the
interior, maintain adequate
ventilation by opening the doors and
windows.
To prevent damage, do not clean
the interior using the following
cleaners or techniques:
.Never use a razor or any other
sharp object to remove a soil
from any interior surface.
.Never use a brush with stiff
bristles.
.Never rub any surface
aggressively or with excessive
pressure.
.Do not use laundry detergents or
dishwashing soaps with
degreasers. For liquid cleaners,use approximately 20 drops per
3.78 L (1 gal) of water.
A concentrated soap solution will
leave a residue that creates
streaks and attracts dirt. Do not
use solutions that contain strong
or caustic soap.
.Do not heavily saturate the
upholstery when cleaning.
.Do not use solvents or cleaners
containing solvents.
Interior Glass
To clean, use a terry cloth fabric
dampened with water. Wipe droplets
left behind with a clean dry cloth.
Commercial glass cleaners may be
used, if necessary, after cleaning
the interior glass with plain water.
Notice:
To prevent scratching,
never use abrasive cleaners on
automotive glass. Abrasive
cleaners or aggressive cleaning
may damage the rear window
defogger. Notice:
Cleaning the windshield
with water during the first three to
six months of ownership will
reduce tendency to fog.
Speaker Covers
Vacuum around a speaker cover
gently, so that the speaker will not
be damaged. Clean spots with just
water and mild soap.
Coated Moldings
Coated moldings should be cleaned.
.When lightly soiled, wipe with a
sponge or soft lint-free cloth
dampened with water.
.When heavily soiled, use warm
soapy water.

10-96 Vehicle Care
Fabric/Carpet/Suede
Start by vacuuming the surface
using a soft brush attachment. If a
rotating brush attachment is being
used during vacuuming, only use it
on the floor carpet. Before cleaning,
gently remove as much of the soil
as possible using one of the
following techniques:
.Gently blot liquids with a paper
towel. Continue blotting until no
more soil can be removed.
.For solid soils, remove as much
as possible prior to vacuuming.
To clean:
1. Saturate a clean lint-free colorfast cloth with water or club
soda. Microfiber cloth is
recommended to prevent lint
transfer to the fabric or carpet.
2. Remove excess moisture by gently wringing until water does
not drip from the cleaning cloth. 3. Start on the outside edge of the
soil and gently rub toward the
center. Rotate the cleaning cloth
to a clean area frequently to
prevent forcing the soil in to the
fabric.
4. Continue gently rubbing the soiled area until there is no
longer any color transfer from
the soil to the cleaning cloth.
5. If the soil is not completely removed, use a mild soap
solution followed only by club
soda or plain water.
If the soil is not completely
removed, it may be necessary to
use a commercial upholstery
cleaner or spot lifter. Test a small
hidden area for colorfastness before
using a commercial upholstery
cleaner or spot lifter. If ring
formation occurs, clean the entire
fabric or carpet.
Following the cleaning process, a
paper towel can be used to blot
excess moisture.
Cleaning High Gloss Surfaces
and Vehicle Information and
Radio Displays
For vehicles with high gloss
surfaces or vehicle displays, use a
microfiber cloth to wipe surfaces.
Before wiping the surface with the
microfiber cloth, use a soft bristle
brush to remove dirt that could
scratch the surface. Then use the
microfiber cloth by gently rubbing to
clean. Never use window cleaners
or solvents. Periodically hand wash
the microfiber cloth separately,
using mild soap. Do not use bleach
or fabric softener. Rinse thoroughly
and air dry before next use.
Notice: Do not attach a device
with a suction cup to the display.
This may cause damage and
would not be covered by the
warranty.
