Fourwheel drive models and
PreRunner10.Lower the vehicle completely
and tighten the wheel nuts.
Turn the jack handle end with the ex-
tension counterclockwise with handle
to lower the vehicle, making sure the
handle remains firmly fitted onto the
jack handle extension.
Use only the wheel nut wrench and
turn it clockwise to tighten the nuts.
Do not use other tools or any addition-
al leverage other than your hands,
such as a hammer, pipe or your foot.
Make sure the wrench is securely en-
gaged over the nut.
Tighten each nut a little at a time in
the order shown. Repeat the process
until all the nuts are tight.
CAUTION
 When lowering the vehicle,
make sure all portions of your
body and all other persons
around will not be injured as
the vehicle is lowered to the
ground.
 Have the wheel nuts tightened
with torque wrench to 113 N·m
(11.5 kgf·m, 85 ft·lbf), as soon
as possible after changing
wheels. Otherwise, the nuts
may loosen and the wheels
may fall off, which could cause
a serious accident.

11. Reinstall the wheel ornament.
Put the wheel ornament into position
and then tap it firmly with the side or
heel of your hand to snap it into place.
CAUTION
Take due care in handling the
ornament to avoid unexpected
personal injury.
 Do not attach a heavily dam-
aged plastic wheel ornament.
It may fly off the wheel and
cause accidents while the ve-
hicle is moving.
12.Check the air pressure of the re-
placed tire.
Adjust the air pressu re to the specifi-
cation designated on page 410 in
Section 8. If the pressure is lower,
drive slowly to the nearest service
station and fill to the correct pressure.
Do not forget to reinstall the tire infla-
tion valve cap as dirt and moisture
could get into th e valve core and
possibly cause air leakage. If the cap
is missing, have a new one put on as
soon as possible.
13.Restow all the tools, jack and flat tire securely.
With a spare tire of the same wheel
type as the installed tires—
As soon after changing wheels as
possible, tighten the wheel nuts to the
torque specified on page 410 in Sec-
tion 8 with a torque wrench. Have a
technician repair the flat tire.
With a spare tire of different wheel
type from the installed tires—

2008 TACOMA from Apr. ’08 Prod. (OM35898U)
As soon after changing wheels as
possible, tighten the wheel nuts to the
torque specified on page 410 in Sec-
tion 8 with a torque wrench. Have a
technician repair the flat tire and re-
place the spare tire with it.
CAUTION
Before driving, make sure all the
tools, jack and flat tire are se-
curely in place in their storage
location to reduce the possibility
of personal injury during a colli-
sion or sudden braking.
If your vehicle becomes stuck in snow,
mud, sand, etc., then you may attempt
to rock the vehicle free by moving it
forward and backward.
If your vehicle is equipped with the
“AUTO LSD” system, you can use it in
this situation. (For details, see “AUTO
LSD system” on page 182 in Section
17.)
If your vehicle is equipped with the
rear differential lock system, you can
use it in this situation. (For details, see
“Rear differential lock system” on page
192 in Section 17.)
CAUTION
Do not attempt to rock the vehicle
free by moving it forward and back-
ward if people or objects are any-
where near the vehicle. During the
rocking operation the vehicle may
suddenly move forward or backward
as it becomes unstuck, causing injury
or damage to nearby people or ob-
jects.
NOTICE
If you rock your vehicle, observe the
following precautions to prevent dam-
age to the transmission and other
parts.
Do not depress the accelerator ped-
al while shifting the selector lever
(automatic transmission) or gear
shift lever (manual transmission), or
before the transmission is com-
pletely shifted to forward or reverse
gear.
 Do not race the engine and avoid
spinning the wheels.
 If your vehicle remains stuck after
rocking the vehicle several times,
consider other ways such as tow-
ing.

2008 TACOMA from Apr. ’08 Prod. (OM35898U)
CAUTION
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 lockedwheel
braking, as use of chains may ad-
versely affect vehicle handling.
When driving with chains installed,
be sure to drive carefully. Slow
down before entering curves to
avoid losing control of the vehicle.
Otherwise an accident may occur.
NOTICE
Snow tires or chains may affect the
tire pressure warning system. See
“Tire pressure warning system” on
page 194 in Section 17.
As you might have difficulty in identify-
ing a flat or deflated tire, a tire pres-
sure warning system is provided on
this vehicle.
When replacing the wheels, be sure to
install tire pressure warning valves and
transmitters on the wheels. Consult your
Toyota dealer about how to set up the tire
pressure warning valves and transmitters.
CAUTION
Have the tires, wheels or tire pres-
sure warning valves and transmit-
ters replaced and ID codes regis-
tered by Toyota dealer. If you need
tire pressure warning valves and
transmitters, purchase from Toyota
dealer.
The tire pressure warning valve and
transmitter nuts should always be
tightened to a torque of 4 N·m (0.4
kgf·m, 2.9 ft·lbf).
The use of nongenuine wheels may
result in the tire pressure warning
system failure or airleak.
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 a damaged wheel,
the tire may slip off the wheel or cause
loss of handling control.
WHEEL SELECTION
When replacing wheels, care should be
taken to ensure that the wheels are re-
placed by ones with the same load ca-
pacity, diameter, rim width, and offset.
Correct replacement wheels are available
at your Toyota dealer.
A wheel of a different size or type may
adversely affect handling, wheel and bear-
ing life, brake cooling, speedometer/odom-
eter calibration, stopping ability, headlight
aim, bumper height, vehicle ground clear-
ance, and tire or snow chain clearance to
the body and chassis.
Replacing wheels

385
2008 TACOMA from Apr. ’08 Prod. (OM35898U)
Replacement with used wheels is not rec-
ommended as they may have been sub-
jected to rough treatment or high mileage
and could fail without warning. Also, bent
wheels which have been straightened may
have structural damage and therefore
should not be used. Never use an inner
tube in a leaking wheel which is designed
for a tubeless tire.
CAUTION
Observe the following instructions.
Otherwise, an accident may occur re-
sulting in death or serious injuries.
Do not use wheels other than the
manufacturer ’s recommended size,
as this may cause dangerous han-
dling characteristics resulting in
loss of control.
Fourwheel drive models:
Do not use wheels of different
brands, sizes and types, as this
may cause dangerous handling
characteristics resulting in loss of
control.
The tire pressure warning system must
be initialized when the specified tire
inflation pressure is changed due to
wheel replacement. See “Tire pressure
warning system” on page 194 in
Section 17.
NOTICE
The use of nongenuine wheels will
cause the air pressure sensors to
transmit the electronic code in differ-
ent manner, resulting in the system
failure.
When installing aluminum wheels,
check that the wheel nuts are tight
after driving your vehicle the first 1600
km (1000 miles). Retorque the wheel
nuts to 113 N·m (11.5 kgf·m, 85 ft·lbf).
If you have rotated, repaired, or
changed your tires, check that the
wheel nuts are still tight after driving
1600 km (1000 miles). Retorque the
wheel nuts to 113 N·m (11.5 kgf·m, 85
ft·lbf).
When using tire chains, be careful not
to damage the aluminum wheels.
Use only Toyota wheel nuts and
wrench designed for your aluminum
wheels.
When balancing your wheels, use only
Toyota balance weights or equivalent
and a plastic or rubber hammer.
As with any wheel, periodically check
your aluminum wheels for damage. If
damaged, replace immediately.

1: If you affix the spare tire to a front position, please make sure to adjust the tire to the correct inflation pressure
as soon as possible.
For sustained high speeds above 160 km/h (100 mph), in countries where such speeds are permitted by law, add
the tire inflation pressure give n below to the front tires and rear tires, but never exceed the maximum cold tire inflation
pressure molded on the tire sidewall.
