4. After the tire is lowered completely to the ground,
remove the holding bracket.
CAUTION
Do not take out the spare tire from under the
vehicle until it is lowered completely to the
ground. When removing the spare tire, take care
that fingers are not pinched between the wheel
and holding bracket.
When storing the spare tire, place it with the outer
side of the wheel facing up. Then secure the tire,
taking care that the tire goes straight up without
catching on any other part, to prevent it from flying
forward during a collision or sudden braking.

Vehicles with kinetic dynamic suspension system Ð
When raising the spare tire, pull the tire toward the
rear of the vehicle. After raising the tire, visually check
that the tire does not interfere with the suspension
components. If interference occurs, lower the spare
tire and start again.
NOTICE
Tighten the spare tire clamp bolt to hold the
spare wheel carrier by the hook securely.
Vehicles with kinetic dynamic suspension
system Ð Make sure that the spare tire does
not interfere with the suspension components
when the spare tire is stowed. If interference
occurs, the suspension system will be
damaged.

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 extension
into the jack (it is a loose fit) and turn it clockwise
with the handle, making sure the handle remains firmly
fitted onto the jack handle extension. As the jack
touches the vehicle and begins to lift, double-check
that it is properly positioned.
CAUTION
Never get under the vehicle when the vehicle
is supported by the jack alone.
7. Remove the wheel nuts and remove the flat tire.
Lift the flat tire straight off and put it aside.
Roll the spare wheel into position and align the holes
in the wheel with the bolts. Then lift up the wheel
and get at least the top bolt started through its hole.
Wiggle the tire and press it back over the other bolts.

CHECKING TIRE INFLATION
PRESSURE
63PY020
The recommended cold tire inflation pressures,
tire sizes and the combined weight of occupants
and cargo (vehicle capacity weight) are described
on page 553 and 606. They are also described
on the tire and loading information label as
shown.
You should check the tire inflation pressure every two
weeks, or at least once a month. And do not forget
the spare!
The following instructions for checking tire
inflation 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 inflation pressure reading.
If you cannot adjust the tire pressure when the
tires are cold, add 20 to 30 kPa more to the front
tires and rear tires than the cold tire pressure, but
never exceed the maximum cold tire pressure
molded on the tire sidewall.
Always use a tire pressure gauge. The
appearance of a tire can be misleading. Besides,
tire inflation pressures that are even just a few
pounds off can degrade handling and ride.

CHECKING AND REPLACING TIRES
When to replace your tires

1New tread2Tread wear indicator
3Worn tread
Replace the tires when the tread wear indicators
show. The location of the tread wear indicators
is shown by the 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.
