95Load index
A numerical code associated with the maximum
load a tire can carry.
HSpeed symbol
A symbol indicating the range of speeds at which
a tire can carry a load corresponding to its load
index under certain operating conditions.
The maximum speed corresponding to the speed
symbol should only be achieved under specified
operating conditions. (i.e. tire pressure, vehicle
loading, road conditions and posted speed limits).
Maximum Load
Maximum load indicates the maximum load this tire is
designed to carry
Maximum Pressure
Maximum Pressure indicates the maximum permissible
cold tire inflation pressure for this tire.
Tire Identification Number (TIN)
The TIN may be found on one or both sides of the tire,
but the date code may only be on one side. Tires with
white sidewalls will have the full TIN including date
code located on the white sidewall side of the tire. Look
for the TIN on the outboard side of black sidewall tires as
mounted on the vehicle. If the TIN is not found on the
outboard side then you will find it on the inboard side of
the tire.

Treadwear, Traction and Temperature Grades
Traction
The treadwear grade is a comparative rating based on the
wear rate of the tire when tested under controlled con-
ditions on a specified government test course. For ex-
ample, a tire graded 150 would wear one and one half
(1 1/2) times as well on the government course as a tire
graded 100. The relative performance of tires depends
upon the actual conditions of their use, however, andmay depart significantly from the norm due to variations
in driving habits, service practices and differences in road
characteristics and climate.
Traction
The traction grades, from highest to lowest, are AA, A, B
and C. Those grades represent the tire's ability to stop on
wet pavement as measured under controlled conditions
on specified government test surfaces of asphalt and
concrete. A tire marked C may have poor traction perfor-
mance.
Temperature
The temperature grades are A (the highest), B and C,
representing the tire's resistance to the generation of heat
and its ability to dissipate heat when tested under
controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the
material of the tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire failure. The
grade C corresponds to a level of performance which all
passenger car tires must meet under the Federal Motor
MAINTENANCE 339

Vehicle Safety Standard No. 109. Grades B and A repre-
sent higher levels of performance on the laboratory test
wheel than the minimum required by law.
Tire inflation pressures
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Three primary
areas are affected by improper tire pressure:
1. Safety
Under-inflation increases tire flexing and can result in tire
failure. Over-inflation results in a tire losing its ability to
cushion shock. Objects on the road and potholes could
cause tire damage that may result in tire failure.
2. Economy
Improper inflation pressures can cause uneven wear
patterns to develop across the tire tread. These abnormal
wear patterns will reduce tread life, resulting in a need
for earlier tire replacement.
Under-inflation also increases tire rolling resistance and
results in higher fuel consumption.
3. Ride comfort and vehicle stability
Proper tire inflation pressures contribute to the excellentride quality built into your vehicle. Over-inflation pro-
duces an uncomfortable and jarring ride.
Under-inflation can produce a feeling of sluggish response.
Unequal inflation pressures can produce erratic and
unpredictable vehicle response to steering maneuvers.
The proper tire pressure for your vehicle is listed on a
placard attached near the door sill striker on the driver's
side ``B''-Pillar.
The recommended inflation pressures should be followed
when the specified tires are installed.
Item Tire size Front Rear
Normal tire P205/60R16 91H 32 psi (220 kpa)
P215/50R17 90H 32 psi (220 kpa)
Compact spare tire T125/70D16 60 psi (420 kpa)
The pressures should be checked and adjusted, if neces-
sary, at least once a month.
Tire pressures should be checked more often when weather
temperatures vary widely, because tire pressures vary with
outdoor temperatures. Inflation pressures specified on the
placard are always ªcold inflation pressureº.
Cold inflation pressure can be measured after the vehicle has
been stationary for at least three hours or driven less than
340 MAINTENANCE

one mile (1.6 km) after being stationary for three hours.
Cold inflation pressure must not exceed the maximum
values molded into the tire sidewall. After driving several
miles, tire inflation pressure may increase 2 to 6 psi (14 to 41
kPa) over the cold inflation pressure; do NOT let air out of
the tires to match the specified cold pressure, or your tires
will be underinflated.
Check your tires each time you refuel. If one tire looks lower
than the others, check the tire inflation pressure for all of
them. The following precautions also should be observed:
1. Keep your tires inflated to the pressures that are
recommended. (See the tire and loading information
placard attached the driver's side ``B''-Pillar.)
2. Stay within the load limits that are recommended.
3. Make sure that the weight of your vehicle load is
evenly distributed.
4. Drive at safe speeds.
5. After the tire inflation pressure has been adjusted,
check the tires for damage and air leaks. Be sure to
replace the rubber caps on the valve stems.
Radial ply tires
Radial ply tires provide improved tread life, road hazard
resistance and smoother high speed ride. The radial ply
factory-installed tires on this vehicle are of belted con-
struction and are selected to complement the ride and
handling characteristics of your vehicle.
Radial ply tires have the same load carrying capacity as
bias or bias-belted tires of the same letter size, and use the
same recommended inflation pressures.
Mixing of radial ply tires with bias or bias-belted tires is
not recommended. Combining radial ply and bias or
bias-belted tires on one vehicle will negatively affect
vehicle handling. It is recommended that radial ply tires
should always be used as a set of four.
As longer wearing tires can be more susceptible to
irregular tread wear, it is very important to follow the tire
rotation interval shown in the section ªTire rotationº to
achieve full tread life potential in these tires.
Cuts and punctures in radial ply tires are repairable only
in the tread area, because of sidewall flexing. Consult
your tire dealer for radial ply tire repairs.

Tire pressure for sustained high-speed driving
For sustained high-speed driving, increase inflation pres-
sure 4 psi (28 kPa) above the recommended pressure but
do not exceed the maximum cold inflation pressure
molded into the tire sidewall.
Replacing tire and wheels
CAUTION!
²Avoid using different size tires from the one listed
and the combined use of different types of tires,
as this can affect driving safety.
Refer to the(TIRES AND WHEELS(on page 377.
²Even if a wheel has the same rim size and offset as
the specified type of wheel, its shape may prevent
it from being fitted correctly. Consult an autho-
rized dealer before using wheels that you have.
Tire maintenance
The following maintenance steps are recommended:
1. Check pressure regularly.
2. Maintain wheel balance and front suspension align-
ment.3. Rotate tires regularly in accordance with the recom-
mendation in the section ªTire rotationº on page 347.
Loading information
WARNING!
Overloading of your tire is dangerous. Overloading can
cause tire failure, affect vehicle handling, and increase
your stopping distance. Use tires of the recommended
load capacity for your vehicle. Never overload them.
It is important to familiarize yourself with the following
terms before loading your vehicle:
²Vehicle maximum load on the tire : load on an indi-
vidual tire that is determined by distributing to each
axle its share of the maximum loaded vehicle weight
and dividing by two.
342 MAINTENANCE

²Vehicle normal load on the tire : load on an individual
tire that is determined by distributing to each axle its
share of the curb weight, accessory weight, and nor-
mal occupant weight and dividing by two.
²Maximum loaded vehicle weight : the sum of ±
(a) Curb weight;
(b) Accessory weight:
(c) Vehicle capacity weight; and
(d) Production options weight.
²Curb weight : the weight of a motor vehicle with
standard equipment including the maximum capacity
of fuel, oil, and coolant, and, if so equipped, air
conditioning and additional weight optional engine.
²Accessory weight : the combined weight (in excess of
those standard items which may be replaced) of auto-
matic transmission, power steering, power brakes,
power windows, power seats, radio, and heater, to the
extent that these items are available as factory-
installed equipment (whether installed or not).
²Vehicle capacity weight : the rated cargo and luggage
load plus 150 lbs (68kg) times the vehicle's designated
seating capacity.
²Production options weight : the combined weight of
those installed regular production options weighing
over 5 lbs (2.3kg) in excess of those standard items
which they replace, not previously considered in curb
weight or accessory weight, including heavy duty
brakes, ride levelers, roof rack, heavy duty battery, and
special trim.
²Normal occupant weight : 150 lbs (68kg) times the
number of specified occupants. (In your vehicle the
number is 3).
²Occupant distribution : distribution of occupants in a
vehicle as specified. (In your vehicle the distribution is
2 in front, 1 in second seat).
Steps for Determining Correct Load Limit
1. Locate the statement9The combined weight of occu-
pants and cargo should never exceed XXX pounds9on
your vehicle's placard.
MAINTENANCE 343
9

2. Determine the combined weight of the driver and
passengers that will be riding in your vehicle.
3. Subtract the combined weight of the driver and pas-
sengers from XXX kilograms or XXX pounds.
4. The resulting figure equals the available amount of
cargo and luggage load capacity. For example, if the
9XXX9amount equals 1400 lbs. and there will be five 150
lb. passengers in your vehicle, the amount of available
cargo and luggage load capacity is 650 lbs. (1400-750 (5 x
150) = 650 lbs.)
5. Determine the combined weight of luggage and cargo
being loaded on the vehicle. That weight may not safely
exceed the available cargo and luggage load capacity
calculated in Step 4.
6. If your vehicle will be towing a trailer, load from your
trailer will be transferred to your vehicle. Consult this
manual to determine how this reduces the available
cargo and luggage load capacity of your vehicle.
NOTE: The above steps for determining correct load
limit were written in accordance with U.S.A. regulations.
Your vehicle cannot tow a trailer, so step 6 is irrelevant.
NOTE:
(1) The following table shows examples on how to
calculate total cargo/load capacity of your vehicle with
varying seating configurations and number and size of
occupants. This table is for illustration purposes only and
may not be accurate for the seating and load capacity of
your vehicle.
(2) For the following example the combined weight of
occupants and cargo should never exceed 865 lbs.
(392kg).
(3) Under a maximum loaded vehicle condition, gross
axle weight ratings (GAWR's) for the front and rear axles
must not be exceeded. For further information on
GAWR's, vehicle loading and trailer towing, see the
9Specifications9section of this manual.
