CAUTION
Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to the
appropriate tire pressure level.
The ABS, VSC and TRC systems will not function correctly if different
tires are fitted on the vehicle.
Contact any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional, for further information when replacing tires or
wheels.
Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will
affect the driving assist systems, and may cause the system to malfunction.

When driving
IS250/220d/200d_EERetighten the chains after driving 0.5  1.0 km (1/4  1/2
mile).
Tire chains (models with 16- and 17-inch tires)
Observe the following precautions when installing and removing chains.
Install and remove tire chains in a safe location.
Install tire chains on the rear tires. Do not install tire chains on front tires.
Install tire chains following the instructions provided in the accompany-
ing manual.
CAUTION
Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in a loss of vehicle control and cause death or
serious injury.
Use tires of the specified size.
Maintain the recommended level of air pressure.
Do not drive at speeds in excess of the speed limit or the speed limit spec-
ified for the snow tires being used.
Driving with tire chains (models with 16- and 17-inch tires)
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in the vehicle being unable to be driven safely,
and may cause death or serious injury.
Do not drive in excess of the speed limit specified for the tire chains being
used or 50 km/h (30 mph), whichever is lower.
Avoid driving on bumpy road surfaces or over potholes.
Avoid sudden turns and braking.
Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.

Tire information
Increase the tire inflation pressure to 20.0 kPa (0.2 kgf/cm2 or bar, 3 psi)
greater than the recommended value when towing. (P. 548)
Increase the air pressure of the trailer tires in accordance with the total
trailer weight and according to the values recommended by the manufac-
turer of your trailer.
Trailer lights
Check that the turn signal lights and stoplights are operating correctly every
time you hitch up the trailer. Directly wiring up to your vehicle may damage
the electrical system and stop the lights from functioning correctly.

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 inflation pressure if not
rotated.
Tire rotation
Models with 16-inch tires (with a compact spare tire or an
emergency tire puncture repair kit)
Rotate the tires in the order
shown.
To equalize tire wear and
help extend tire life, Lexus
recommends that you rotate
your tires approximately
every 10000 km (6000
miles).
Models with 16-inch tires (with a full-size spare tire)

NOTICE
Driving on rough roads
Take particular care when driving on roads with loose surfaces or pot holes.
These conditions may cause losses in tire air 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 vehicle’s wheels and body.
Low profile tires and wheels (vehicles with 17- and 18- inch tires)
Wheels with profile tires may cause greater damage than usual to the tire
wheel when receiving 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 pot holes, uneven pavement, curbs and other road hazards.
Failure to do so may lead to severe tire and wheel damage.
If tire pressures become 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 refilling, have it checked by any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
Instructions for checking tire 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 and has not been
driven for more than 1.5 km or 1 mile, you will get an accurate cold tire
inflation pressure reading.
Always use a tire pressure gauge.
The appearance of the tire can be misleading. In addition, tire inflation
pressures that are even just a few pounds off can degrade ride and han-
dling.
Do not bleed or reduce tire inflation pressure after driving. It is normal
for the 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 the 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
weeks.
