Toyota AURION Owner's Manual page 276

Tyres deteriorate with age even if they have
never or seldom been used.
This applies also to the spare tyre and tyres
stored for future use.
REPLACING YOUR TYRES
When replacing a tyre, use a tyre of the
same size and construction, and the same
or greater load capacity as the originally
installed tyres.
Using any other size or type of tyre may seri-
ously affect handling, ride, speedometer/
odometer calibration, ground clearance, and
clearance between the body and tyres or
snow chains.
CAUTION
Observe the following instructions.
Otherwise, an accident may occur re-
sulting in death or serious injuries.
Do not mix radial, bias belted, or bias-
D
ply tyres on your vehicle, as this may
cause dangerous handling character-
istics resulting in loss of control.
Do not use tyres other than the manu-
D
facturer's recommended size, as this
may cause dangerous handling char-
acteristics resulting in loss of control.
Never use second-hand tyres on your
Toyota.
Using tyres whose previous history is un-
known is a risk.
Toyota recommends all four tyres, or at
least both front or rear tyres be replaced
at a time as a set.
See "If you have a flat tyre" on page 224 in
Section 4 for tyre change procedure.
When a tyre is replaced, the wheel should
always be balanced.
An unbalanced wheel may affect vehicle han-
dling and tyre life. Wheels can get out of bal-
ance with regular use and should therefore
be balanced occasionally.
DO-IT-YOURSELF MAINTENANCE -- ENGINE AND CHASSIS
When replacing a tubeless tyre, the air
valve should also be replaced with a new
one.
