ROTATING TIRES

63E005–1

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.

Worn tread

Replace the tires when the tread wear indicators show. The

location of the tread wear indicators is shown by the marks such

as ”TWI” or ”

∆” 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.).
