ROTATING TIRES
To equalize tire wear and help extend tire life, Lexus
recommends that you rotate your tires approximately
every 12000 km (7500 miles). 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 treadTread wear indicatorWorn tread
Replace your tires when the tread wear indicators show.
The location of the tread wear indicators is shown by
the ªTWIº or ªDº 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.).
