Tires
Replace or rotate tires in accordance with maintenance schedules and
treadwear.

Wo r n t r e a d
The location of treadwear
indicators is shown by the
“TWI” or “” marks, etc.,
molded on the sidewall of
each tire.
Check spare tire condition
and pressure if not rotated.
Tire rotation
Rotate the tires in the order
shown.
To equalize tire wear and
help extend tire life, Lexus
recommends that tire rotation
is carried out approximately
every 10000 km (6000

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
cushioning ability of the tires. In addition, driving on rough roads may cause
damage to the tires themselves, as well as the vehicle’s wheels and body.
Low profile tires (vehicles with 17 inch tires)
Low profile tires may cause greater damage 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.

Tire inflation pressure
Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
Reduced fuel efficiency
Reduced driving comfort and tire life
Reduced safety
Damage to the drive train
If a tire needs frequent inflating, have it checked by any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours or has not been driven
for more than 1.5 km or 1 mile, you will get an accurate cold tire infla-
tion pressure reading.
Always use a tire pressure gauge.
The appearance of the tire can be misleading. In addition, tire inflation
pressure that is even just a few pounds off can affect ride quality and
handling.
Do not reduce tire inflation pressure after driving. It is normal for tire
inflation pressure to be higher after driving.
Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is
balanced.
Make sure to maintain proper tire inflation pressure. Tire inflation
pressure should be checked at least once per month. However, Lexus
recommends that tire inflation pressure be checked once every two

CAUTION
Proper inflation is critical to save tire performance
Keep your tires properly inflated. Otherwise, the following conditions may
occur and result in an accident causing death or serious injury:
Excessive wear
Uneven wear
Poor handling
Possibility of blowouts resulting from overheated tires
Poor sealing of the tire bead
Wheel deformation and/or tire separation
A greater possibility of tire damage from road hazards
NOTICE
When inspecting and adjusting tire inflation pressure
Be sure to put the tire valve caps back on.
Without the valve caps, dirt or moisture could get into the valve and cause
air leakage, which could result in an accident. If the caps are lost, replace
them as soon as possible.

The compact spare tire
The compact spare tire is identified by the label “TEMPORARY USE
ONLY” on the tire sidewall.
Use the compact spare tire temporarily, and only in an emergency.
Make sure to check the tire inflation pressure of the compact spare tire.
(P. 661)
If you have a flat front tire on a road covered with snow or ice
Install the compact spare tire on one of the rear wheels of the vehicle. Per-
form the following steps and fit tire chains to the front tires:
Replace a rear tire with the compact spare tire.
Replace the flat front tire with the tire removed from the rear of the
vehicle.
Fit tire chains to the front tires.

valve of the punctured tire.
Remove the air release cap
from the hose.
Connect the hose to the valve.
Screw the end of the hose
clockwise as far as possible.

When trouble arises
CT200h_OM_OM76067E_(EE)To inject the sealant and inflate
the tire, turn the compressor
switch on.
Use the kit with the top facing
upward.
Inflate the tire until the recom-
mended pressure is reached.
The sealant will be injected
and the pressure will spike
to 300 kPa (3.0 kgf/cm
2
or bar, 44 psi) or 400 kPa
(4.0 kgf/cm2 or bar, 58 psi),
then gradually decrease.
The air pressure gauge will
display the actual tire infla-
tion pressure about 1 minute
after the switch is turned on.
• Turn the compressor switch
off and then check the tire
inflation pressure. Being
careful not to over inflate,
check and repeat the infla-
tion procedure until the rec-
ommended tire inflation
pressure is reached.
