When to replace your tires
62L023

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
∆
"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.

Vehicles equipped with 225/55R17 97W tires: Your Lexus
has been fitted with specially developed tires which provide
exceptional dynamic performance under general road
conditions. However your riding comfort may worsen a little
and road noise may increase during driving. You may also
notice that your tires will wear more rapidly and tire grip
performance will be reduced on the snowy and/or icy roads
when compared to standard tires. Be sure to have snow tires
or tire chains on the snowy and/or icy roads and drive carefully
with the speed appropriate for road conditions.
NOTICE
Avoid driving onto high, sharp–edged objects and other
road hazards. Failure to do so can lead to severe tire
damage.
The effectiveness of snow tires is lost if the tread wears
down below 4 mm (0.16 in.).
If you have tire damage such as cuts, splits, cracks deep
enough to expose the fabric, or bulges indicating internal
damage, the tire should be replaced.
If a tire often goes flat or cannot be properly repaired due to the
size or location of a cut or other damage, it should be replaced.
If you are not sure, consult with your Lexus dealer.
If an air loss occurs while driving, do not continue driving with
a deflated tire. Driving even a short distance can damage a tire
beyond repair.
