ROTATING TIRES
63X005
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.

1 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.).
