CHECKING TIRE PRESSURE
The recommended cold tire pressures, tire size and the
vehicle capacity weight are given on the label inside the
glovebox lid.
You should check the tire pressures every two weeks, or at
least once a month. Arid don’t forget the spare! The air
pressure for the spare tire should be 30 kPa (0.3 kg / cm
2 or bar,
4 psi) above the recommended cold tire pressure. Incorrect tire
pressure can reduce tire life and make your vehicle less safe
to drive.
Low tire pressure results in excessive wear, poor handling,
reduced fuel economy, and the possibility of blowouts from
overheated tires. Also, low tire pressure can cause poor
sealing of the tire bead. If the tire pressure is excessively low,
there is the possibility of wheel deformation and / or tire
separation. So keep your tire pressures at the proper level. If
a tire needs frequent refilling, have it checked by your Lexus
dealer.High tire pressure produces a harsh ride, handling problems.
excessive wear at the center of the tire tread, and a greater
possibility of tire damage from road hazards.
The following instructions for checking tire pressure should be
observed:
The pressure should be checked only when the tires are
cold. If your vehicle has been parked for at least 3 hours and
has not been driven for more than 1.5 km or 1 mile since, you
will get an accurate cold tire pressure reading.
Always use a tire pressure gauge. The appearance of the
tire can be misleading. Besides, tire pressures that are even
just a few pounds off can degrade handling and ride.
Do not bleed or reduce tire pressure after driving. It is
normal for the tire pressure to be higher after driving.
Never exceed the vehicle capacity weight. The
passenger and luggage weight should be located so that the
vehicle is balanced.
Be sure to reinstall the tire valve caps. Without the valve
caps, dirt or moisture could get into the valve core and
cause air leakage. If the caps have been lost, have new
ones put on as soon as possible.

ROTATING TIRES
To equalize tire wear and help extend tire life, Lexus
recommends that you rotate your tires approximately
every 12000 km (7500 miles). However, the most
appropriate timing for tire rotation may vary according to
your driving habits and road surface conditions.
The wheel assemblies must be rotated only between the front
and rear as illustrated above.
When rotating tires, check for uneven wear and damage.
Abnormal wear is usually caused by incorrect tire pressure,
improper wheel alignment, out-of-balance wheels, or severe
braking.
Before storing radial, snow or studded tires, mark the direction
of rotation and be sure to install them in the same direction
when using them again. Tires should be stored in a cool dry
place.
CHECKING AND REPLACING TIRES
When to replace your tires
New treadTread wear indicatorWorn 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
show you 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.
The effectiveness of snow tires is lost if the tread wears
down below 4 mm (0.16 in.).

INSTALLING SNOW TIRES AND
CHAINS
When to use snow tires or chains
Snow tires or chains are recommended when driving on
snow or ice.
On wet or dry roads, conventional or radial tires provide better
traction than snow or studded tires.
Snow tire selection
If you need snow tires, select the same size, construction
and load capacity as the original tires on your Lexus.
Do not use tires other than stated above. Since your vehicle
has radial tires as original equipment, make sure your snow
tires also have radial construction. Do not install studded tires
without first checking local regulations for possible restrictions.
Snow tire installation
Snow tires should be installed on all wheels.
Installing snow tires on the front wheels only can lead to an
excessive difference in road grip capability between the front
and rear tires, which could cause loss of vehicle control.CAUTION:
Snow tires should be inflated to the same pressure as
the original tires.
Never drive over 120 km / h (75 mph) with any type of
snow tires.
Tire chain selection
Regulations regarding the use of tire chains vary
according to region and type of road. Always check the
local regulations before installing chains.
Use SAE Class “S” type radial tire chains, with the exception
of radial cable chains or V-bar type chains.
Chain installation
When installing chains on your tires, carefully follow the
instructions of the chain manufacturer.
Install the chains on the front tires as tightly as possible. Do not
use tire chains on the rear tires. Retighten chains after driving
0.5 − 1.0 km (1 / 4 − 1 / 2 mile).
CAUTION:
Do not exceed 50 km / h (30 mph) or the chain
manufacturer’s recommended speed limit, whichever
is lower.
Drive carefully avoiding bumps, holes, and sharp turns,
which may cause the vehicle to bounce.
Avoid sharp turns or locked-wheel braking, as use of
chains may adversely affect vehicle handling.
