324 6-3. Do-it-yourself maintenance
Replace the tires if the treadwear indica-
tors are showing on a tire.
■
When to replace your vehicle’s tires
Tires should be replaced if:
●
The treadwear indicators are showing on
a tire.
●
You have tire damage such as cuts, splits,
cracks deep enough to expose the fabric,
and bulges indicating internal damage
●
A tire goes flat repeatedly or cannot be
properly repaired due to the size or loca-
tion of a cut or other damage
If you are not sure, consult your Lexus
dealer.
■
Tire life
Any tire over 6 years old must be checked
by a qualified technician even if it has sel-
dom or never been used or damage is not
obvious.
■
Low profile tires
Generally, low profile tires will wear more
rapidly and tire grip performance will be
reduced on snowy and/or icy roads when
compared to standard tires. Be sure to use
snow tires or tire chains on snowy and/or icy
roads and drive carefully at a speed appro-
priate for road and weather conditions.
■
If the tread on snow tires wears down
below 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is
lost.
WARNING
■
When inspecting or replacing tires
Observe the following precautions to
prevent accidents.
Failure to do so may cause damage to
parts of the drivetrain as well as danger-
ous handling characteristics, which may
lead to an accident resulting in death or
serious injury.
●
Do not mix tires of different makes,
models or tread patterns.
Also, do not mix tires of remarkably
different treadwear.
●
Do not use tire sizes other than those
recommended by Lexus.
●
Do not mix differently constructed
tires (radial, bias-belted or bias-ply
tires).
●
Do not mix summer, all season and
snow tires.
●
Do not use tires that have been used
on another vehicle.
Do not use tires if you do not know
how they were used previously.
●
Vehicles with a compact spare tire: Do
not tow if your vehicle has a compact
spare tire installed.
●
Vehicles with an emergency tire punc-
ture repair kit: Do not tow anything if a
tire that has been repaired using the
emergency tire puncture repair kit is
installed. The load on the tire may
cause unexpected damage to the tire.
NOTICE
■
Low profile tires
Low profile tires may cause greater dam-
age than usual to the tire wheel when
sustaining impact from the road surface.
Therefore, pay attention to the following:
●
Be sure to use proper tire inflation
pressure. If tires are under-inflated,
they may be damaged more severely.
●
Avoid potholes, uneven pavement,
curbs and other road hazards. Failure
to do so may lead to severe tire and
wheel damage.
■
If tire inflation pressure of each tire
becomes low while driving
Do not continue driving, or your tires
and/or wheels may be ruined.
