have the legally prescribed mini-
mum height of 1.6 mm, approxi-
mately 0.06 in.
The positions of the wear displays
are identified on the tyre's side wall
by TWI, Tread Wear Indicator.
Inspect tyres regularly for damage,
the presence of foreign bodies and
wear.
Vehicle behaviour that may indicate
tyre damage or other faults:
• Unusual vibrations.
• Unusual tyre or running noises.
• Unusual vehicle response, such
as pronounced pulling to the left
or right.
Damage can be caused by the fol-
lowing situations, for example:
• Driving over kerbs.
• Road damage.
• Tyre inflation pressure insuffi-
cient.
• Vehicle overloading.
• Incorrect tyre storage.
Irrespective of the tyre tread depth,
change tyres after 6 years at the
latest.
The date of manufacture of the tyre
is indicated on the tyre sidewall.
Tyre damage
General
Safety notes
WARNING
If the tyres are damaged, the tyre
inflation pressure may be reduced,
which in turn could cause you to lose
control of the vehicle. There is a dan-
ger of accidents. If you suspect tyre
damage while you are driving, imme-
diately reduce speed and bring the
vehicle to a stop. Have the wheels
and tyres checked. To do so, carefully
drive to any authorized Toyota retailer
or Toyota authorized repairer, or any
reliable repairer. If necessary, have
the vehicle towed or transported
there. Do not repair damaged tyres,
but have them replaced instead.
WARNING
Tyres can become damaged by run-
ning over obstacles, for example
kerbs or road damage, at high speed.
Larger wheels have a smaller tyre
cross-section. The smaller the tyre
cross-section, the higher the risk of
tyre damage. There is a danger of
accidents and damage to property. If
possible, drive around obstacles or
drive over them slowly and carefully.

Information on the correct
wheel/tyre combination and rim
designs for the vehicle can be
obtained from any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
Certain makes of tyre are recom-
mended by the manufacturer of the
vehicle for each tyre size. The tyre
brands can be identified by a star
on the side wall of the tyre.

Safety notes
WARNING
Wheels and tyres that are not suitable
for your vehicle can damage parts of
the vehicle. For example they could
come into contact with the bodywork
on account of their dimensional toler-
ances, despite having the same nomi-
nal size. There is a danger of
accidents. The manufacturer of the
vehicle recommends using wheels
and tyres that have been categorised
as suitable for the respective vehicle
type.
WARNING
Mounted steel wheels can lead to
technical problems, for example
wheel studs may work loose or brake
discs may be damaged. There is a
danger of accidents. Do not install
steel wheels.
WARNING
Incorrect wheel/tyre combinations
impair the vehicle's handling charac-
teristics and interfere with the proper
functioning of various systems, such
as the Anti-lock Brake System or
Vehicle Stability Control. There is a
danger of accidents. To maintain good
vehicle handling, always fit tyres of
the same make and tread pattern to
all wheels. The manufacturer of the
vehicle recommends using wheels
and tyres that have been categorised
as suitable for the respective vehicle
type. After a tyre has been damaged,
refit the same wheel/tyre combination
as the original.

Due to the manufacturing process,
new tyres do not provide maximum
grip immediately.
Drive moderately for the first 300
km, 200 miles.
The manufacturer of your vehicle
advises against the use of
retreaded tyres.
Winter tyres are recommended if
driving in winter conditions.
Although so-called all-season tyres
with an M+S label have better win-
ter characteristics than summer
tyres, they do not normally match
the performance of winter tyres.
If winter tyres are fitted, observe
and do not exceed the respectively
permitted maximum speed.For your own safety, only use
run-flat tyres. There is no spare
wheel available in the event of a
breakdown. Additional information
is available from any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
Swapping the front wheels with the
rear wheels or vice versa is not per-
mitted on vehicles with different tyre
or rim dimensions on the front and
rear axles.
Do not exceed the maximum tyre
inflation pressure indicated on the
tyre's side wall.
Store wheels and tyres in a cool,
dry and dark place when not in use.
Protect the tyres against contami-
nation from oil, grease and sol-
vents.
Do not leave tyres in plastic bags.
Remove dirt from the wheels or
tyres. New tyres
Retreaded tyres
WARNING
Retreaded tyres may have different
tyre carcasses. Their durability may
be reduced with increasing age.
There is a danger of accidents. Do
not use retreaded tyres.

Supra Owner's Manual5-1. MOBILITY
In the event of a complete loss of
tyre inflation pressure, run-flat tyres
enable you to continue driving, with
certain restrictions.
The wheels are fitted with tyres
which are self-supporting to a lim-
ited degree. They may also have
special rims.
The reinforced side wall means that
the tyre keeps the vehicle mobile to
a degree even if tyre inflation pres-
sure has been lost.
Observe the notes on continuing to
drive with a flat tyre.The tyres are identified on the tyre's
side wall by RSC Runflat System
Component.
• Park the vehicle on a firm sur-
face and as far away from mov-
ing traffic as possible.
• Switch on the hazard warning
lights.
• Apply the parking brake to pre-
vent the vehicle rolling away.
• Engage the steering wheel lock
with the wheels in the
straight-ahead position.
• Have all vehicle occupants get
out of the vehicle and guide them
out of the danger area, for exam-
ple behind the crash barrier.
• Set up the warning triangle an
appropriate distance away.
Run-flat tyres
Principle
General
Safety notes
WARNING
A run-flat tyre which has low tyre infla-
tion pressure or no tyre inflation pres-
sure at all will change the vehicle's
handling characteristics, for example
there may be reduced directional sta-
bility when braking, longer braking
distances and different self-steering
characteristics. There is a danger of
accidents. Drive with care and do not
exceed a speed of 80 km/h, 50 mph.

With the Mobility System, minor
tyre damage can be quickly sealed,
to allow you to drive on. For this
purpose, liquid sealant is pumped
into the tyres which encloses the
damage from the inside when it
hardens.
• Please observe the notes on the
application of the Mobility Sys-
tem which are on the compres-
sor and the sealant container.
• Applying the Mobility System can
be ineffective for tyre damage
larger than approximately 4 mm.
• Contact any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer if
you are unable to put the tyre
back in operation.
• If possible, foreign matter that
has penetrated the tyre should
remain inside the tyre. Only
remove foreign objects if they
are visibly protruding from the
tyre.
• Remove the speed limit sticker
from the sealant container and
attach to the steering wheel.
• Using sealants can damage the
TPM wheel electronics. In this
case, have the electronics
replaced at the next opportunity.• The compressor can be used to
check the tyre inflation pressure.
The Mobility System is located in the
right storage compartment of the boot.

Safety notes
WARNING
A blocked exhaust pipe or inadequate
ventilation can allow harmful exhaust
fumes to enter the vehicle. The
exhaust fumes contain pollutants
which are colourless and odourless.
In enclosed spaces, the exhaust
fumes can also build up outside the
vehicle. There is a danger of fatal
injury. Keep the exhaust pipe clear
and ensure sufficient ventilation.
NOTICE
The compressor can overheat if oper-
ated for too long. There is a danger of
damage to property. Do not let the
compressor run for longer than 10
minutes.

2Pull filler hose completely from
the cover of the sealant con-
tainer. Do not kink the hose.
3Push the sealant container into
the bracket on the compressor
housing, until it audibly
engages.
4Screw the filler hose of the seal-
ant container onto the tyre valve
of the faulty wheel.5Insert the plug into the socket in
the vehicle interior while the
compressor is switched off.
6Switch on the compressor with
standby state switched on or the
engine running.
Let the compressor run for approxi-
mately 10 minutes to fill the sealing
compound and achieve a tyre infla-
tion pressure of approximately 2.0
bar.
The tyre inflation pressure may rise
to approximately 5 bar during the
filling process of the sealing com-
pound. Do not switch off the com-
pressor during this step.
