ROTATING TIRES
63L020a
To equalize tire wear and help extend tire life, Lexus
recommends that you rotate your tires according to the
maintenance schedule. (For scheduled maintenance
information, please refer to the “Owner’s Manual
Supplement / Scheduled Maintenance”.) However, the
most appropriate timing for tire rotation may vary
according to your driving habits and road surface
conditions.
The wheel assemblies must be rotated as illustrated above.
When rotating tires, check for uneven wear and damage.
Abnormal wear is usually caused by incorrect tire pressure,
improper wheel alignment, out−of balance wheels, or severe
braking.
Before storing radial, snow or studded tires, mark the direction
of rotation and be sure to install them in the same direction
when using them again. Tires should be stored in a cool dry
place.
CHECKING AND REPLACING TIRES
When to replace your tires

New tread
2
Tread wear indicator
3
Worn tread
Replace the tires when the tread wear indicators show.
The location of the tread wear indicators is shown by the
marks molded on the sidewall of each tire.
The tires on your Lexus have built−in tread wear indicators to
help you know when the tires need replacement. When the
tread depth wears to 1.6 mm (0.06 in.) or less, the indicators
will appear. If you can see the indicators in two or more
adjacent grooves, the tire should be replaced.
The effectiveness of snow tires is lost if the tread wears
down below 4 mm (0.16 in.).
