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 four wheel drive
models, all the tires must be the
same brand and have the same
tread patterns.
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 sidewall of the
tire and the Certification Label, see
“Tire information” on page 457 in
S ec t ion 2 and “Your Toy ot a’s
identification” on page 455 in Section
2.
CAUTION
Observe the following instruc-
tions. Otherwise, an accident
may occur resulting in death or
serious injuries.
Do not mix radial, bias belted,
or bias ply 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.
Do not use tires of different
brands, sizes and construc-
tions. This may damage the
drive system and prevent the
vehicle stability control system
from functioning correctly.
Four wheel 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
503 in Section 4 for tire change proce-
dure.
When a tire is replaced, the wheel
should always be balanced.

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).

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.
