If air loss occurs while driving, do not
continue driving. Driving even a short
distance can damage a tire beyond
repair.
An y ti res wh i ch are over 6 years
old must be checked by a qualified
technician even if damage is not
obvious.
Tires deteriorate with age even if they
have never or seldom been used.
This applies also to the spare tire and
tires stored for future use.
REPLACING YOUR TIRES
When replacing a tire, use a tire of
the same size and construction,
and the same or greater maximum
load as the originally installed
tires. Also, on allwheel drive mod-
els, all the tires must be the same
brand and have the same tread pat-
terns.Using any other size or type of tire
may seriously affect handling, ride,
speedometer/odometer calibration,
ground clearance, and clearance be-
tween the body and tires or snow
chains.
Check that the maximum load of the
replaced tire is greater than 1/2 of the
Gross Axle Weight Ratings (GAWR)
of either the front axle or the rear
axle, whichever is greater. As for the
maximum load of the tire, see the load
limit at maximum cold tire inflation
pressure mentioned on the sidewall
of the tire, and as for the Gross Axle
Weight Ratings (GAWR), see the Cer-
tification Label.
For details about the side wall of the
tire and the Certification Label, see
pages 386 and 388.
CAUTION
Observe the following instruc-
tions. Otherwise, an accident
may occur resulting in death or
serious injuries.

Do not mix radial, bias belted,
or biasply tires on your ve-
hicle, as this may cause dan-
gerous handling characteris-
tics resulting in loss of control.
 Do not use tires other than the
manufacturer’s recommended
size, as this may cause danger-
ous handling characteristics
resulting in loss of control.
 Allwheel drive models:
Do not use tires of different
brands, sizes, construction or
tread patterns, as this may
cause dangerous handling
characteristics resulting in
loss of control.

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 tire” on page
421 in Section 4 for tire change proce-
dure.
When a tire is replaced, the wheel
should always be balanced.
An unbalanced wheel may affect ve-
hicle 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
w i t h a new on e.
Initial adjustment of the tire pres-
sure warning system is necessary
after you have rotated your tires.
See “Tire pressure warning sys-
tem” on page 196 in Section 17.
To equalize the wear and help ex-
tend tire life, Toyota recommends
that you rotate your tires accord-
ing to the maintenance schedule.
(For scheduled maintenance infor-
mation, please refer to the “Sched-
uled Maintenance Guide” or “Own-
er’s Manual Supplement”.)
However, the most appropriate tim-
ing for tire rotation may vary ac-
cording to your driving habits and
road surface conditions.
See “If you have a flat tire” on page
421 in Section 4 for tire change proce-
dure. When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire pres-
sure, improper wheel alignment, out
−
of −balance wheels, or severe braking.
CAUTION
Do not include a compact spare
tire when rotating the tires. It is
designed for temporary use only.
Initial adjustment of the tire pres-
sure warning system is necessary
after you have rotated your tires.
See “Tire pressure warning sys-
tem” on page 196 in Section 17.
Rotating tires

Some vehicles are equipped with
runflat (RFT) tires. The runflat
tire allows you to continue driving
for up to 160 km (100 miles) at a
speed below 90 km/h (55 mph)
even if any tire goes flat. However,
in some conditions (such as high
temperatures), you could not con-
tinue driving for up to 160 km (100
miles).
When the tire goes flat or when the
tire pressure is below 100 kPa (1.0
kgf/cm
2 or bar, 15 psi), the tire
must be replaced. If you are not
sure, consult your Toyota dealer.
Do not use the repaired tire. There is an “RFT” or “DSST” mark on
the sidewall of the run
−flat tire.
If you cannot distinguish between the
standard tire and run −flat tire, consult
your Toyota dealer.
The tire warranty book provides de-
tailed information on the run −flat tires.
For details, see the tire warranty
book.
CAUTION
 Do not use nongenuine
wheels, as this may cause dan-
gerous handling characteris-
tics resulting in loss of control.
 Do not use the runflat tires
equipped on your vehicle on
another model. These tires are
especially for this model.
 Do not mix runflat tires with
standard tires.
If the tire pressure warning light
co mes on :
Decelerate at a speed below 90
km/h (55 mph), then adjust the tire
pressure to the specified level as
soon as possible. Do not drive
more than 160 km (100 miles).
 When the tire pressure is below
140 kPa (1.4 kgf/cm
2 or bar, 20
psi), consult your Toyota deal-
er. If the tire is flat or the tire
pressure is below 100 kPa (1.0
kgf/cm
2 or bar, 15 psi), the tire
must be replaced. Do not use
the repaired tire.
 When the tire pressure is 140
kPa (1.4 kgf/cm
2 or bar, 20 psi)
or more, adjust it to specified
level. (See “Tires” on page 499
in Section 8.)
For details about the tire pressure
warning system, se e “Tire pressure
warning system” on page 196 in Sec-
tion 1 −7.

Vehicles with compact spare tire—
When you replace the tire, see
“—Compact spare tire” through “—Af-
ter changing wheels”, pages 423
through 435 in Section 4.
CAUTION
As the runflat tire allows you to
continue driving if any tire goes
flat, the tire performance is not
the same as normal condition. If
the runflat tire goes flat, take
your vehicle to the nearest Toyo-
ta dealer or authorized tire dealer
as soon as possible, observing
the following instructions:
Decelerate as soon as possible
to the lowest appropriate
speed that conditions permit.
Do not drive for longer than
160 km (100 miles) or over 90
km/h (55 mph).
Avoid abrupt steering wheel
maneuvering and braking. If
t h e veh i cl e ti res det eri o rat e,
you could lose control of the
steering wheel or the brakes,
causing death or serious inju-
ry.
 Do not replace or repair the tire
by yourself. When the tires
must be replaced or repaired,
consult your Toyota dealer or
authorized tire dealer.NOTICE
 Take due care not to go over
a curb stone and be careful
of the holes in the road be-
cause deflated tire pressure
affects tire cushion perfor-
mance. The wheels, tires,
body, suspension and other
components could be dam-
aged.
 Your ground clearance is re-
duced if the runflat tire
goes flat so avoid driving
over obstacles and drive
slowly on rough, unp aved
roads and speed bumps.
Also, do not attempt to go
through an automatic car
wash as the vehicle may get
caught, resulting in damage.

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.
Allwheel drive models:
Do not use wheels of different
brands, sizes and types, as this
may cause dangerous handling
characteristics resulting in loss of
control.
Initial adjustment of the tire pressure
warning system is necessary after you
have replaced your wheels. See “Tire
pressure warning system” on page 196
in Section 17.When installing aluminum wheels,
check that the wheel nuts are tight
after driving your vehicle the first 1600
km (1000 miles).
If you have rotated, repaired, or
changed your tires, check that the
wheel nuts are still tight after driving
1600 km (1000 miles).
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.
