Types of tires
This vehicle is one of the class of ve-
hicles which have higher ground
clearance and narrower tread in rela-
tion to the height of their center of
gravity to make them capable of per- forming in a wide variety of off-road applications. Specific design charac-
teristics give it a hi
gher center or grav-
ity than ordinary cars. An advantage ofthe higher ground clearance is a better view of the road allowing you to antici-
pate problems. It is not designed for
cornering at the same speeds as con-
ventional two-wheel drive vehicles
any more than low-slung sports cars
are designed to perform satisfactorily under off-road conditions.
CAUTION!
Always observe the following pre-
cautions to m inimize the risk of seri-
ous personal injury or damage to
your vehicle: Avoid sharp turns or abrupt ma-
neuvers, if at all possible. As with
other vehicles of this type, failure
to operate this vehicle correctly
may result in loss of control or ve-
hicle rollover.
Avoid loading any items on the
roof that will make the center of
gravity even higher.
Always slow down in gusty cross-
winds. Because of its high center
of gravity, your vehicle is more
sensitive to side winds than an or-
dinary passenger car. Slowing
down will allow you to have much
better control.
Do not drive horizontally across steep slopes. Driving straight up
or straight down is preferred. Your
vehicle (or any similar off-road ve-
hicle) can tip over sideways much
more easily than forward or back- ward.

6. After making sure that no one is inthe vehicle, raise it high enough so
that the spare tire can be installed.
Remember you will need more ground
clearance when putting in the spare tirethan when removing the flat tire.
To raise the vehicle, insert the jack handle
into the jack (it is a loose fit) and turn it
clockwise. As the j ack touches the vehicle
and begins to lift, double-check that it is
properly positioned.
Never get under the vehicle when it is supported by the jack alone. CAUTION
!
7. Remove the wheel nuts and change
tires.
Lift the flat tire straight off and put it aside.
Roll the spare wheel into position and
align the holes in the wheel with the bolts.
Then lift up the wheel and get at least thetop bolt started through its hole. Wigglethe tire and press it back over the other bolts.Before putting on wheels, remove any
corrosion on the mounting surfaces with a
wire brush or such. Installation of wheels
without good metal-to-metal contact at
the mounting surface can cause wheel
nuts to loosen and eventually cause a
wheel to come off while driving. Therefore
after the first 1600 km (1000 miles), check
to see that the wheel nuts are tight.

CHECKING YOUR TIRES Check the tire tread for the tread wear
indicators. If the indicators show, re-
place the tires.
The tires on your Toyota have built-in tread wear indicators to help you know
when the tires need replacement. When
the tread depth wears to 1.6 mm (0.06 in.)
or less, the indicators will appear. If you
can see the indicators in two or more adja-
cent grooves, the tire should be replaced.
The lower the tread, the higher the risk of skidding. The effectiveness of snow tires is lost
if the tread wears down below 4 mm (0.16 in.).Check the tires regularly for damage
such as cuts, splits and cracks. If any
damage is found, consult with a tech-
nician and have the tire repaired or re- placed. Even if the damage does not appear seri-
ous, a qualified technician should ex-
amine the damage. Objects which have penetrated the tire may have caused in-ternal damage.
Any tires which are over six years old
must be checked by a qualified techni-
cian even if damage is not obvious.
Tires deteriorate with age even if they
have never or seldom been used.
This
also applies to the spare tire and tires
stored for future use. REPLACING YOUR TIRES
When replacing a tire, use only the
same size and construction as origi-
nally installed and with the same or
greater load capacity.
Using any other size or type of tire may se-
riously affect handling, ride, speedomeet-
er/odometer calibration, ground clear-
ance, and clearance between the body
and tires or snow chains.
CAUTION
Do not mix radial, bias belted, or
bias-ply tires on your vehicle. It
can cause dangerous handling
characteristics, r esulting in loss of
control.
Do not use tires or wheels other
than the manufacturer's recom-
mended size.!
Toyota recommends all four tires, or at
least both of the front or rear tires be
replaced at a time as a set.
See If you have a flat tireº in Part 4 for tire
change procedure.
When a tire is replaced, the wheel
should always be balanced.
An unbalanced wheel may affect vehicle
handling and tire life. Wheels can get out
of balance with regular use and should
therefore be balanced occasionally.
When replacing a tubeless tire, the air
valve should also be replaced with a
new one.
Checking and replacing tires

CAUTION
Do not drive with the snow tires in- correctly inflated.
Never drive over 120 km/h (75 mph)
with any type of snow tires.!
TIRE CHAIN SELECTION Use the tire chains of correct size.
Regulations regarding the use of tire
chains vary according to location or
type of r oad, so always check them be-
fore installing chains.
CHAIN INSTALLATION
Install the chains on the rear tires as
tightly as possible. Do not use tire
chains on the front tires. Retighten
chains after driving 0.5 '1.0 km
(1/4 '1/2 mile).
When installing chains on your tires, care- fully follow the instructions of the chain
manufacturer.
If wheel covers are used, they will be
scratched by the chain band, so removethe covers before putting on the chains.
Do not exceed 50 km/h (30 mph) or
the chain manufacturer's recom-
mended speed limit, whichever is
lower.
Drive carefully avoiding bumps,
holes, and sharp turns, which may cause the vehicle to bounce.
Avoid sharp turns or locked-wheel
braking, as use of chains may ad- versely affect vehicle handling.
CAUTION! WHEN TO REPLACE YOUR WHEELS
If you have wheel damage such as
bending, cracks or heavy corrosion,
the wheel should be replaced.
If you fail to replace damaged wheels, the
tire may slip off the wheel or they may cause loss of handling control. WHEEL SELECTION
When replacing wheels, care should
be taken to ensure that the wheels are
replaced by ones with the same load
capacity, diameter, rim width, and off- set.
Correct
replacement wheels are available
at your Toyota dealer.
A wheel of a different size or type may ad-
versely affect handling, wheel and bear-
ing life, brake cooling, speedometer/
odometer calibration, stopping ability,
headlight aim, bumper height, vehicle
ground clearance, and tire or snow chain clearance to the body and chassis.
Replacement with used wheels is not rec-
ommended as they may have been sub- jected to rough treatment or high mileageand could fail without warning. Also, bent
wheels which have been straightened
may have structural damage and there-
fore should not be used. Never use an in-
ner tube in a leaking wheel which is de-
signed for a tubeless tire.
