(2) Tire Width:The three-digit
number indicates the tire section
width in millimeters from
sidewall to sidewall.
(3) Aspect Ratio:Atwo-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:Aletter
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.
Aspect Ratio:The relationship
of a tire's height to its width.
Belt:Arubbercoatedlayerof
cords between the plies and the
tread. Cords may be made from
steel or other reinforcing
materials.
Bead:The tire bead contains
steel wires wrapped by steel
cords that hold the tire onto
the rim.
Bias Ply Tire:Apneumatictire
in which the plies are laid at
alternate angles less than
90 degrees to the centerline of
the tread.
Cold Tire Pressure:The
amount of air pressure in a tire,
measured in kPa (kilopascal)
or psi (pounds per square inch)
before a tire has built up heat
from driving. SeeTire
Pressure0405.
Curb Weight:The weight of a
motor vehicle with standard and
optional equipment including the

406 Vehicle Care
Caution
Neither tire underinflation nor
overinflation is good.
Underinflated tires, or tires
that do not have enough air,
can result in:
.Tire overloading and
overheating which could
lead to a blowout.
.Premature or
irregular wear.
.Poor handling.
.Reduced fuel economy.
Overinflated tires, or tires that
have too much air, can
result in:
.Unusual wear.
.Poor handling.
.Rough ride.
.Needless damage from
road hazards.
The Tire and Loading
Information label on the vehicle
indicates the original equipment
tires and the correct cold tire
inflation pressures. The
recommended pressure is the
minimum air pressure needed to
support the vehicle's maximum
load carrying capacity.
For additional information
regarding how much weight the
vehicle can carry, and an
example of the Tire and Loading
Information label, seeVehicle
Load Limits0259.Howthe
vehicle is loaded affects vehicle
handling and ride comfort. Never
load the vehicle with more
weight than it was designed to
carry.
When to Check
Check the tires once a month
or more.
Do not forget the spare tire,
if the vehicle has one. See
Full-Size Spare Tire0431for
additional information.
How to Check
Use a good quality pocket-type
gauge to check tire pressure.
Proper tire inflation cannot be
determined by looking at the tire.
Check the tire inflation pressure
when the tires are cold, meaning
the vehicle has not been driven
for at least three hours or no
more than 1.6 km (1 mi).
Remove the valve cap from the
tire valve stem. Press the tire
gauge firmly onto the valve to
get a pressure measurement.
If the cold tire inflation pressure
matches the recommended
pressure on the Tire and
Loading Information label, no
further adjustment is necessary.
If the inflation pressure is low,
add air until the recommended
pressure is reached. If the

416 Vehicle Care
{Warning
Mixing tires of different sizes,
brands, or types may cause
loss of control of the vehicle,
resulting in a crash or other
vehicle damage. Use the
correct size, brand, and type
of tires on all wheels.
This vehicle may have a
different size spare than the
road tires originally installed
on the vehicle. When new, the
vehicle included a spare tire
and wheel assembly with a
similar overall diameter as the
road tires and wheels, so it is
all right to drive on it. The
spare tire was developed for
use on this vehicle and will not
affect vehicle handling.
{Warning
Using bias-ply tires on the
vehicle may cause the wheel
rim flanges to develop cracks
after many miles of driving.
Atireand/orwheelcouldfail
suddenly and cause a crash.
Use only radial-ply tires with
the wheels on the vehicle.
Winter tires with the same speed
rating as the original equipment
tires may not be available for H,
V, W, Y a n d Z R s p e e d r a t e d
tires. Never exceed the winter
tires’maximum speed capability
when using winter tires with a
lower speed rating.
If the vehicle tires must be
replaced with a tire that does not
have a TPC Spec number, make
sure they are the same size,
load range, speed rating, and
construction (radial) as the
original tires.
Vehicles that have a tire
pressure monitoring system
could give an inaccurate
low-pressure warning if non-TPC
Spec rated tires are installed.
SeeTire Pressure Monitor
System0407.
The Tire and Loading
Information label indicates the
original equipment tires on the
vehicle. SeeVehicle Load Limits
0259for the label location and
more information about the Tire
and Loading Information label.
Different Size Tires and
Wheels
If wheels or tires are installed thatare a different size than the originalequipment wheels and tires, vehicleperformance, including its braking,ride and handling characteristics,stability, and resistance to rollovermay be affected. If the vehicle haselectronic systems such as antilockbrakes, rollover airbags, roll bars,traction control, electronic stability

Warning (Continued)
without the proper amount of
clearance can cause damage to
the brakes, suspension, or other
vehicle parts. The area damaged
by the tire chains could cause you
to lose control of the vehicle and
you or others may be injured in a
crash.
Use another type of traction
device only if its manufacturer
recommends it for use on the
vehicle and tire size combination
and road conditions. Follow that
manufacturer's instructions. To
help avoid damage to the vehicle,
drive slowly, readjust, or remove
the device if it is contacting the
vehicle, and do not spin the
vehicle's wheels.
If you do find traction devices that
will fit, install them on the rear
tires.
Caution
If the vehicle does not have dual
wheels and has a tire size other
than 265/65R18, P265/65R18,
P275/55R20, LT265/70R17,
LT 2 6 5 / 7 0 R 1 8 , LT 2 6 5 / 6 0 R 2 0 ,
LT 2 7 5 / 6 5 R 1 8 , P 2 8 5 / 5 0 R 2 0 ,
285/45R22, or P285/45R22, use
tire chains only where legal and
only when you must. Use chains
that are the proper size for the
tires. Install them on the tires of
the rear axle. Do not use chains
on the tires of the front axle.
Tighten them as tightly as
possible with the ends securely
fastened. Drive slowly and follow
the chain manufacturer's
instructions. If you can hear the
chains contacting the vehicle,
stop and retighten them. If the
contact continues, slow down
until it stops. Driving too fast or
spinning the wheels with chains
on will damage the vehicle.
If a Tire Goes Flat
It is unusual for a tire to blowoutwhile driving, especially if the tiresare maintained properly. If air goesout of a tire, it is much more likely toleak out slowly. But if there ever is ablowout, here are a few tips aboutwhat to expect and what to do:
If a front tire fails, the flat tirecreates a drag that pulls the vehicletoward that side. Take your foot offthe accelerator pedal and grip thesteering wheel firmly. Steer tomaintain lane position, and thengently brake to a stop, well off theroad, if possible.
Arearblowout,particularlyonacurve, acts much like a skid andmay require the same correction asused in a skid. Stop pressing theaccelerator pedal and steer tostraighten the vehicle. It may bevery bumpy and noisy. Gently braketo a stop, well off the road,if possible.

four-wheel drive and a different sizespare tire is installed, drive only intwo-wheel drive.
After installing the spare tire on thevehicle, stop as soon as possibleand check that the spare tire iscorrectly inflated.
Have the damaged or flat road tirerepaired or replaced and installedback onto the vehicle as soon aspossible so the spare tire will beavailable in case it is needed again.
Do not mix tires and wheels ofdifferent sizes, because they will notfit. Keep your spare tire and itswheel together. If the vehicle has aspare tire that does not match theoriginal road tires and wheels in sizeand type, do not include the spare inthe tire rotation.
