●

Always use a tire pressure gauge.

It is difficult to judge if a tire is properly 

inflated based only on its appearance.

●

It is normal for the tire inflation pressure 

to be higher after driving as heat is gen-

erated in the tire. Do not reduce tire infla-

tion pressure after driving.

●

Never exceed the vehicle capacity 

weight.

Passengers and luggage weight should 

be placed so that the vehicle is balanced.

When replacing wheels, care should 
be taken to ensure that they are equiv-
alent to those removed in load capac-
ity, diameter, rim width and inset

*

.

Replacement wheels are available at 
your Lexus dealer.

*

: Conventionally referred to as offset.

Lexus does not recommend using the 
following:



Wheels of different sizes or types



Used wheels



Bent wheels that have been straight-
ened

■

When replacing wheels

The wheels of your vehicle are equipped 

with tire pressure warning valves and trans-

mitters that allow the tire pressure warning 

system to provide advance warning in the 

event of a loss in tire inflation pressure. 

Whenever wheels are replaced, tire pres-

sure warning valves and transmitters must 

be installed. (

WARNING

■

Proper inflation is critical to save tire 

performance

Keep your tires properly inflated.

If the tires are not properly inflated, the 

following conditions may occur which 

could lead to an accident resulting in 

death or serious injury:

●

Excessive wear

●

Uneven wear

●

Poor handling

●

Possibility of blowouts resulting from 

overheated tires

●

Air leaking from between tire and 

wheel

●

Wheel deformation and/or tire dam-

age

●

Greater possibility of tire damage 

while driving (due to road hazards, 

expansion joints, sharp edges in the 

road, etc.)

NOTICE

■

When inspecting and adjusting tire 

inflation pressure

Be sure to put the tire valve caps back on.

If a valve cap is not installed, dirt or mois-

ture may get into the valve and cause an 

air leak, resulting in decreased tire infla-

tion pressure.

Wheels

If a wheel is bent, cracked or heavily 
corroded, it should be replaced. 
Otherwise, the tire may separate 
from the wheel or cause a loss of 
handling control.

When replacing wheels

●

Do not use wheels that are a different 

size from those recommended in the 

Owner’s Manual, as this may result in a 

loss of handling control.
