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 with 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.
■
If the tread on snow tires wears down
below 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is
lost.
Rotate the tires in the order shown.

Vehicles with front and rear tires of
the same size

Vehicles with front and rear tires of
differing sizes
WARNING
■
When inspecting or replacing tires
Observe the following precautions to
prevent accidents.
Failure to do so may cause damage to
parts of the drive train 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.
NOTICE
■
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.
