Checking using tire inflation

pressure specifications in

the tire inflation pressure

table

The current tire inflation pres-

sure values and the intended

tire inflation pressure values for

the mounted tires can be dis-

played on the Control Display.

The tire inflation pressure speci-

fications in the tire inflation pres-

sure table only relate to cold

tires or tires at the same tem-

perature as the ambient tem-

perature.

To ensure that they are dis-

played correctly, the tire sizes

must be stored in the system

and must have been set, refer to

page 280, for the mounted tires.

Only check the tire inflation

pressure levels when the tires

are cold, i.e.:

• Driving range of max. 1.25

miles/2 km has not been

exceeded.

• If the vehicle has not moved

again for at least 2 hours after

a trip.

The current tire inflation pres-

sure value is located on each

tire.

The reference tire inflation pres-

sure value is located in the

lower area of the Control Dis-

play.

Check the tire inflation pressure

of the emergency wheel in the

cargo area regularly, and correct

it as needed.

Checking the tire inflation

pressure

General information

1 Determine, refer to page 264,

the intended tire inflation

pressure levels for the

mounted tires.

Tires heat up while driving. The

tire inflation pressure increases

with the tire temperature.

2 Check the tire inflation pres-

sure in all four tires, using a

pressure gauge, for example.

Tires have a natural, consistent

loss of tire inflation pressure.

The displays of inflation devices

may under-read by up to 0.1

bar/2 psi.

3 Correct the tire inflation pres-

sure if the actual tire inflation

pressure deviates from spec-

ified tire inflation pressure.

The traction grade assigned to

this tire is based on

All passenger vehicle tires must

conform to Federal Safety

Requirements in addition to

these grades

straight-ahead braking traction

tests, and does not include

acceleration, cornering, hydro-

planing, or peak traction charac-

teristics.

Treadwear

The treadwear grade is a com-

parative rating based on the

wear rate of the tire when tested

under controlled conditions on a

specified government test

course. E.g., a tire graded 150

would wear one and one-half, 1

g, times as well on the govern-

ment course as a tire graded

100. The relative performance

of tires depends upon the actual

conditions of their use, however,

and may depart significantly

from the norm due to variations

in driving habits, service prac-

tices and differences in road

characteristics and climate.

Temperature

The temperature grades are A,

the highest, B, and C, represent-

ing the tire's resistance to the

generation of heat and its ability

to dissipate heat when tested

under controlled conditions on a

specified indoor laboratory test

wheel. Sustained high tempera-

ture can cause the material of

the tire to degenerate and

reduce tire life, and excessive

temperature can lead to sudden

tire failure.

The grade C corresponds to a

level of performance which all

passenger vehicle tires must

meet under the Federal Motor

Vehicle Safety Standard No.

109. Grades Band A represent

higher levels of performance on

the laboratory test wheel than

the minimum required by law.

Traction

The traction grades, from high-

est to lowest, are AA, A, B, and

C.

Those grades represent the

tire's ability to stop on wet pave-

ment as measured under con-

trolled conditions on specified

government test surfaces of

asphalt and concrete. A tire

marked C may have poor trac-

Minimum tread depth

WARNING

The temperature grade for this tire

is established for a tire that is

properly inflated and not over-

loaded. Excessive speed, under-

inflation, or excessive loading,

either separately or in combina-

tion, can cause heat buildup and

possible tire failure.

M+S

Wear indicators are distributed

around the tire's circumference

and have the legally required

minimum height of 0.063

inches/1.6 mm.

Winter and all-season tires with

better cold weather performance

than summer tires.

Tire tread

The positions of the wear indica-

tors are marked on the tire side-

wall with TWI, Tread Wear

Indicator.

Summer tires

5

Do not drive with a tire tread of

less than 0.12 in/3 mm, other-

wise there is an increased risk

of hydroplaning.

Tire damage

General information

Winter tires

Inspect your tires regularly for

damage, foreign objects lodged

in the tread, and tread wear.

Do not drive with a tire tread of

less than 0.16 in/4 mm, as such

tires are less suitable for winter

operation.

Driving over rough or damaged

road surfaces, as well as debris,

curbs and other obstacles can

cause serious damage to

wheels, tires and suspension

parts. This is more likely to

occur with low-profile tires,

which provide less cushioning

between the wheel and the

road. Be careful to avoid road

hazards and reduce your speed,

especially if your vehicle is

Supra Owner's Manual_U (from Jul. '20 Prod.)

5-1. MOBILITY

equipped with low-profile tires.

WARNING

Indications of tire damage or

other vehicle malfunctions:

• Unusual vibrations.

• Unusual tire or running

noises.

• Unusual handling such as a

strong tendency to pull to the

left or right.

Tires can become damaged by

driving over obstacles, e.g., curbs

or road damage, at high speed.

Larger wheels have a smaller tire

crosssection. The smaller the tire

cross-section, the higher the risk

of tire damage. There is a danger

of accidents and property dam-

age. If possible, avoid driving over

objects or road conditions that

may damage tires, or drive over

them slowly and carefully.

Damage can be caused by the

following situations, for instance:

• Driving over curbs.

• Road damage.

• Tire inflation pressure too low.

• Vehicle overloading.

Changing wheels and

tires

Mounting and wheel bal-

ancing

• Incorrect tire storage.

Safety information

WARNING

Have mounting and wheel bal-

ancing carried out by your Toy-

ota dealer.

Damaged tires can lose tire infla-

tion pressure, which can lead to

loss of vehicle control. There is a

risk of an accident. If tire damage

is suspected while driving, imme-

diately reduce speed and stop.

Have wheels and tires checked.

For this purpose, drive carefully to

the nearest your Toyota dealer.

Have vehicle towed or trans-

ported as needed. Do not repair

damaged tires, but have them

replaced.

Wheel and tire combina-

tion

General information

You can ask your Toyota dealer

about the correct wheel/tire

combination and wheel rim ver-

sions for the vehicle.

Supra Owner's Manual_U (from Jul. '20 Prod.)

5-1. MOBILITY

Safety information

WARNING

Recommended tire brands

Wheels and tires which are not

suitable for your vehicle can dam-

age parts of the vehicle, for

instance due to contact with the

body due to tolerances despite

the same official size rating.

There is a risk of an accident. The

manufacturer of your vehicle

strongly suggests that you use

wheels and tires that have been

recommended by the vehicle

manufacturer for your vehicle

type.

For each tire size, the manufac-

turer of the vehicle recommends

certain tire brands. The tire

brands can be identified by a

star on the tire sidewall.

WARNING

Mounted steel wheels can cause

technical problems, for instance

unexpected loosening of the lug

bolts and damage to the brake

discs. There is a risk of accident.

Do not mount steel wheels.

New tires

5

Tire traction is not optimal due to

manufacturing circumstances

when tires are brand-new; they

achieve their full traction poten-

tial after a break-in time.

WARNING

Incorrect wheel/tire combinations

will have a negative impact on the

vehicle's handling and on the

function of a variety of systems,

such as the Anti-lock Brake Sys-

tem or Vehicle Stability Control

System. There is a risk of an acci-

dent. To maintain good handling

and vehicle response, use only

tires with a single tread configura-

tion from a single manufacturer.

The manufacturer of the vehicle

recommends that you use wheels

and tires that have been recom-

mended by the vehicle manufac-

turer for your vehicle type.

Drive conservatively for the first

200 miles/300 km.

Retreaded tires

WARNING

Retreaded tires can have different

tire casing structures. With

advanced age the service life can

be limited. There is a risk of an

accident. The manufacturer of

your vehicle does not recommend

the use of retreaded tires.

Following tire damage, have the

original wheel/tire combination

remounted on the vehicle as soon

as possible.

The manufacturer of your vehi-

cle does not recommend the

use of retreaded tires.

Winter tires

Storing tires

General information

Tire inflation pressure

Winter tires are recommended

for operating on winter roads.

Do not exceed the maximum tire

inflation pressure indicated on

the side wall of the tire.

Although so-called all-season

M+S tires provide better winter

traction than summer tires, they

usually do not provide the same

level of performance as winter

tires.

Storage

Store wheels and tires in a cool,

dry and dark place.

Always protect tires against all

contact with oil, grease, and sol-

vents.

Maximum speed of winter

tires

Do not leave tires in plastic

bags.

If the maximum speed of the

vehicle is higher than the per-

missible speed for the winter

tires, then attach a label show-

ing the permissible maximum

speed in the field of view. The

label is available from your Toy-

ota dealer.

Remove dirt from wheels or

tires.

be met for the system; other-

wise, reliable flagging of a loss

of tire inflation pressure is not

assured:

• After each tire or wheel

change, the system detects

and updates the mounted

tires and displays them after a

short trip on the Control Dis-

play.

5

The tire sizes of the mounted

tires can be gathered from the

tire inflation pressure details on

the vehicle, refer to page 264, or

directly on the tires.

The tire details do not need to

be re-entered when the tire infla-

tion pressure is corrected.

For summer and winter tires, the

tire details entered last are

stored. After a tire or wheel

replacement, the settings of the

tire sets used last can be

selected.

Enter the information about the

mounted tires in the tire settings

when the system does not automat-

ically detect the tires.

Temperature

Malfunction

Message

The tire inflation pressure

depends on the tire's tempera-

ture.

The yellow warning

light flashes and is then

illuminated continu-

ously. A vehicle mes-

sage is displayed. It

may not be possible to

identify tire pressure

losses.

Driving or exposure to the sun

will increase the tire's tempera-

ture, thus increasing the tire

inflation pressure.

The tire inflation pressure is

reduced when the tire tempera-

ture falls again.

Measure

• A wheel without TPM wheel

electronics, such as an emer-

gency wheel, is mounted:

have the wheels checked, if

needed.

These circumstances may

cause a warning when tempera-

tures fall very sharply.

Following a temperature-related

warning, the target pressures

are displayed on the Control

Display again after a short dis-

tance.

• Malfunction: have the system

checked.

tems or devices with the

same radio frequency: after

ference, the system automati-

cally becomes active again.

tale. Your vehicle has also

been equipped with a TPMS

malfunction indicator to indi-

cate when the system is not

operating properly. The TPMS

malfunction indicator is com-

bined with the low tire pres-

sure telltale. When the system

detects a malfunction, the tell-

tale will flash for approxi-

mately one minute and then

remain continuously illumi-

nated. This sequence will

continue upon subsequent

vehicle start-ups as long as

the malfunction exists. When

the malfunction indicator is

illuminated, the system may

not be able to detect or signal

low tire pressure as intended.

TPMS malfunctions may

occur for a variety of reasons,

including the installation of

replacement or alternate tires

or wheels on the vehicle that

prevent the TPMS from func-

tioning properly. Always

check the TPMS malfunction

more tires or wheels on your

vehicle to ensure that the

pressure recommended by

the vehicle manufacturer on

the vehicle placard or tire

inflation pressure label. (If

your vehicle has tires of a dif-

ferent size than the size indi-

cated on the vehicle placard

or tire inflation pressure label,

you should determine the

proper tire inflation pressure

for those tires.) As an added

safety feature, your vehicle

has been equipped with a tire

pressure monitoring system

(TPMS) that illuminates a low

tire pressure telltale when one

or more of your tires is signifi-

cantly under-inflated. Accord-

ingly, when the low tire

pressure telltale illuminates,

you should stop and check

your tires as soon as possi-

ble, and inflate them to the

proper pressure. Driving on a

significantly under-inflated tire

causes the tire to overheat

and can lead to tire failure.

Under-inflation also reduces

fuel efficiency and tire tread

life, and may affect the vehi-

cle's handling and stopping

ability. Please note that the

TPMS is not a substitute for

proper tire maintenance, and

it is the driver's responsibility

to maintain correct tire pres-

sure, even if under-inflation

has not reached the level to

trigger illumination of the

TPMS low tire pressure tell-
