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.
Your vehicle is equipped with 245/40ZR18 or 245/40ZR18
93Y 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.
Riding comfort and road noise with the run–flat tires may be a
little worse than that with the standard tires. 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 high aspect ratio tires, etc. 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
Low profile tire like 245/40ZR18 or 245/40ZR18 93Y may
have greater damage than usual tires to its tire wheel
when receiving impact from the road surface.
Therefore, pay attention to the following.
Be sure to use with proper tire pressure. If the tire
pressure is low, the tire may have greater damage.
For detailed information about tire pressure, see
page 318 or 321.
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.
