6-3. Do-it-yourself maintenance
Replace the tires if the treadwear indica-
tors are showing on a tire.
Q When to replace your vehicle’s tires
O 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 any authorized
Lexus retailer or Lexus authorized repairer,
or any reliable repairer.
O Vehicles with 17-inch tires:
The wheel angle differs from vehicles
equipped with 18-inch/19-inch tires.
Therefore, 18-inch/19-inch tires cannot
be installed, as sufficient gaps with sur-
rounding parts cannot be ensured.
Q 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.
Q Low profile tires (18-inch/19-inch 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 on snowy and/or icy roads and
drive carefully at a speed appropriate for
road and weather conditions.
Q If the tread on snow tires wears down
below 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is
lost.
Q 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.
O Do not mix tires of different makes,
models or tread patterns.
Also, do not mix tires of remarkably
different treadwear.
O Do not use tire sizes other than those
recommended by Lexus.
O Do not mix differently constructed
tires (radial, bias-belted or bias-ply
tires).
O Do not mix summer, all season and
snow tires.
O 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.
Q Driving on rough roads
Take particular care when driving on
roads with loose surfaces or potholes.
These conditions may cause losses in tire
inflation pressure, reducing the cushion-
ing ability of the tires. In addition, driving
on rough roads may cause damage to
the tires themselves, as well as the vehi-
cle’s wheels and body.
Q Low profile tires (18-inch/19-inch
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:
