Toyota 2006 Sienna Owner's Manual page 486

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.
06 SIENNA_U (L/O 0603)
D 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.
D Do not use tires other than the
manufacturer's recommended
size, as this may cause danger-
ous handling characteristics
resulting in loss of control.
D All- wheel drive models:
Do not use tires of different
brands, sizes, construction or
tread patterns, as this may
cause dangerous handling
characteristics resulting
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
with a new one.
in
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 208 in Section 1- 7.
