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 a torque wrench to the fol-
lowing torques, as soon as
possible after changing
wheels. Retighten the wheel
nuts within 160 km (100 miles)
of driving. Otherwise, the nuts
may loosen and the wheels
may fall off, which could cause
a serious accident.
Due to the higher torque
specification for these wheel
nuts, if in doubt about the
correct tightness, have them
checked by your Toyota deal-
er or at a service station.

Torque specification:
Taper type (Steel wheels)—
209 N· m (21. 3 kgf · m , 154 ft · lbf )
Flat washer type
(Aluminum wheels)—
131 N·m (13.4 kgf·m, 97 ft·lbf)
∗
∗
: When temporarily used on spare tire/wheel, apply 209 N·m (21.3
kgf·m, 154 ft·lbf) 10.Check the air pressure of the re-
placed tire.
Adjust the air pressu re to the specifi-
cation designated on page 594 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.
11. Restow all the tools, jack and flat tire securely.
As soon after changing wheels as
possible, tighten the wheel nuts to the
torque specified on page 515 with a
torque wrench. Have a technician re-
pair the flat tire and replace the tem-
porary spare tire with it. Initial adjustment of the tire
pressure warning system is
necessary after your have replaced
your tires or wheels. See “Tire
pressure warning system” on page
254 in Section 17.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.

2008 TUNDRA from Apr. ’08 Prod. (OM 34477U)
As you might have difficulty in
identifying a flat or deflated tire, a tire
pressure 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. 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.
Replacing wheels

2008 TUNDRA from Apr. ’08 Prod. (OM 34477U)
When installing wheels, check that the
wheel nuts are tight after driving your
vehicle the first 160 km (100 miles).
If you have rotated, repaired, or
changed your tires, check that the
wheel nuts are still tight after driving
160 km (100 miles).
Wheel nut torque.
Steel wheel: 209 N·m (21.3 kgf·m, 154 ft·lbf)
Aluminum wheel:
131 N·m (13.4 kgf·m, 97 ft·lbf)
When using tire chains, be careful not
to damage the aluminum wheels.
Use only the Toyota wheel nuts and
wrench designed for your aluminum
wheels.
When balancing your aluminum wheels,
use only Toyota balance weights or
equivalent and a plastic or rubber ham-
mer.
As with any wheel, periodically check
your aluminum wheels for damage. If
damaged, replace immediately.
