To remove the spare tire:
1Remove the spare tire cover.
2Loosen the bolt and remove it.
When storing the spare tire, place it with the inner side
of the wheel facing up. Then bolt the tire in place and
install the spare tire cover to prevent the tire from flying
forward during a collision or sudden braking.

6. After making sure no one is in the vehicle, raise
it high enough so that the spare tire can be installed.
Allow for the fact that you need more ground clearance
when putting on the spare tire than when removing the
flat tire.
To raise the vehicle, insert the jack handle into the jack
(it is a loose fit) and turn it clockwise. As the jack touches
the vehicle and begins to lift, double±check that it is
properly positioned.

422The recommended cold tire pressures, tire size and
the vehicle capacity weight are given on the label
inside the glove box lid.
You should check the tire pressures every two weeks, or
at least once a month. And don't forget the spare! The
pressure for the spare tire should be 220 kPa (2.2
kgf/cm
2 or bar, 32 psi). 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 pr essures 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
passengers 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.

1New tread 2Tread wear indicator
3Worn tread
Replace the tires when the tread wear indicators
show. The location of the tread wear indicators is
shown by the ºTWIº or º
Dº marks molded on the
sidewall of each tire.
The tires on your Lexus have built±in tread wear
indicators to help you know 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.). If you have tire damage such as cuts, splits, cracks
deep enough to expose the fabric, or bulges
indicating internal damage, the tire should be
replaced.
If a tire often goes flat or cannot be properly repaired due
to the size or location of a cut or other damage, it should
be replaced. If you are not sure, consult with your Lexus
dealer.
If an air loss occurs while driving, do not continue driving
with a deflated tire. Driving even a short distance can
damage a tire beyond repair.
Any tires which are over 6 years old must be
checked by a qualified technician even if damage is
not obvious.
Tires deteriorate with age even if they have never or
seldom been used.
This also applies to the spare tire and tires stored for
future use.
